OPINION

In this appeal by allowance, we granted allocatur to consider, inter alia, the collateral order doctrine and whether a plaintiff in a civil personal injury action has the right to have counsel present and to record a neuropsychological examination of that plaintiff by a defendant’s neuropsychologist under Pennsylvania Rule of Civil Procedure 4010. For the reasons set forth below, we find that Appellants have not satisfied the collateral order doctrine, and, thus, we quash the present appeal as an unauthorized interlocutory appeal, vacate the' order of the Superior Court, and remand the matter- to the court of common pleas for further proceedings.

The facts underlying this matter are not in. dispute. On July 15, 2010, Appellee Scott Hafer was operating a motor vehicle owned by his mother, Appellee Paulette Ford. .Appellant Diana Shearer (hereinafter “Mrs. Shearer”) alleged that Hafer pulled- his- vehicle into the path of the vehicle that- she was. driving, causing an accident. As a result of the collision, Mrs. Shearer and her husband Jeff Shearer (collectively, “Appellants”) commenced a personal injury action against Hafer and Ford (collectively, “Appellees”) in the Lebanon County Court of Common Pleas. Appellants’ claims included damages for cognitive harm to Mrs. Shearer caused by the accident, including a closed head injury that resulted in headaches, cognitive impairment, and memory deficits. In preparation for trial, Appellants hired a neurop-sychologist, Dr. Paul Eslinger, who was associated with the Hershey Medical Center, to perform a cognitive evaluation. This evaluation, which employed standardized testing procedures, was conducted without Appellants’ counsel or any other third party present.

In response to the evaluation, Appellees hired Dr. Victor Malatesta, also a neurop-sychologist, to perform an independent neuropsychological evaluation as part of their defense. Appellants did not oppose the- request for an independent neuropsy-chological .examination, but demanded that the evaluation be audiotaped, and that their counsel, or other representative, be present during all stages of the examination.

Upon learning of Appellants’ preconditions, Dr. Malatesta objected based on asserted ethical grounds, and because he believed such observation could result in the introduction of bias to the process, distortion of the data, and distraction of Mrs. Shearer. Specifically, he claimed that he was bound by the ethical principles of psychologists and the Code of Conduct of the American Psychological Association (“APA”)' and the National Academy of Neuropsychology (“NAN”) to protect the integrity of the examination and the security of the test materials. Dr. Malatesta indicated, however, that, as a compromise, he would permit Appellants” counsel to be present during the interview portion of the examination, but would not permit the presence of counsel or audiotaping during the standardized testing phase of his evaluation.

Appellants’ counsel rejected the doctor’s proposed compromise and sought the trial court’s intervention, Following briefing by both parties, including additional information .concerning the alleged practical and ethical restraints on the presence of third parties, the trial court entered an order granting Appellees’ request for a protective order; however, the court stipulated that Appellants’ counsel could be present during the preliminary interview phase of the exam, but that no individual would be permitted in the evaluation room with Mrs. Shearer and the doctor during the standardized test, nor could the evaluation be recorded. The trial court reached this determination after considering Pennsylvania Rule of Civil Procedure 4010, which, as we discuss below, governs defense requested physical and mental examinations, and provides that the person to be examined shall have the right to have counsel or other representative present during an ex-animation, as well as- Pennsylvania Rule of Civil Procedure 4012, which allows for protective orders, for good cause shown, to protect a party or person from whom discovery is sought from unreasonable conduct. ■

Appellants moved for reconsideration of the trial court’s order, and for certification of the matter as appealable pursuant to Pa.R.A.P. 1311(b) (concerning interlocutory appeals by permission). The trial court denied the motions, and Appellants appealed to the Superior Court. ^[1]

■ A three-judge panel of the Superior Court affirmed the trial court’s order. Shearer v. Hafer, 135 A.3d 637 (Pa. Super. 2016). Writing for the court, Judge Jack Panella first considered whether the court had jurisdiction under the collateral order doctrine. See Pa.R.A.P. 313(b). The court recognized that discovery orders generally are deemed interlocutory, and not immediately appealable, because they do not finally dispose of the litigation; however, the court recognized that, pursuant to Rule 313, a non-final order may be reviewed if: (1) it is separable from and collateral to the main cause of action; (2) the right involved is too important to be denied review; and (3) the question presented is such that, if review is postponed until final judgment in the case, the claim will be irreparably' lost. The Superior Court reasoned that the order granting the protective order prohibiting the presence of third parties' .during the neuropsychological exam was separable from, and collateral to, the main cause of action; that any matter implicating a litigant’s right to have counsel present is, too important to be denied review; and that, if the question presented were postponed until final judgment, Appellants’ claim concerning ‘ their right to have counsel present would be irreparably lost. Accordingly, the court found the order was a collateral order pursuant, to Rule 313.

Proceeding to the merits of the appeal, the Superior Court examined Pa.R.C.P. 4010, which pertains to the physical and mental examination .of persons, and. was amended in 1998 to explicitly include the examinee’s right to have counsel present •during such examination. The Rule provides, in relevant part, that a person “to be examined shall have the.right to have counsel or other representative, present during the examination,”,.and that “[t]he party who is being examined ... may have made upon reasonable notice and at the party’s’ expense a stenographic, or audio recording of the examination.” Pa.R.C.P. 4010(a)(4), (a)(5) (emphasis added). The court rejected Appellants’ argument that the plain language, of Rule .4010, granting the .right to. have counsel present during the examination, is absolute. Rather, the court reasoned that, while use of the term “shall” is usually mandatory, it may nevertheless be discretionary depending upon the intent of the drafter of the rule, and that such intent, .is discerned from considering various factors of statutory construction. . .

The Superior Court next looked to Pa. R.C.P. 4012, concerning protective orders, and reasoned that Rule 4012 was intended to give the trial court the discretion, to issue protective orders in various discovery scenarios, including the power to limit the number of individuals present. Thus, absent any. indication, that Rule 4010 was intended to curb the powers granted by Rule 4012, the panel concluded the trial court’s power to issue protective' orders expressly encompasses the ability to limit the number of individuals present during all discovery, including psychological examinations. Shearer, 135 A.3d at 643-44.

The court went on to conclude, however, that Rule 4012 does not empower a trial court to issue protective orders carte blanche; and that the rule places on the party seeking the protective order the burden of showing “good cause.” To determine what constitutes “good cause,” the court looked to its en banc decision in Dougherty v. Heller, 97 A.3d 1257 (Pa. Super. 2014), in which', at the time of the Superior Court’s decision in the instant case, this Court had granted review, in part. ^[2] Finding no basis to disturb the trial court’s determination that Appellees had established good cause to warrant a protective order, the Superior Court herein echoed the trial court’s finding that the official statements from NAN, and the APA’s Ethical Principles of Psychologists and its Code of Conduct, were persuasive that third-party observers should be excluded from the standardized test portion of the examination to keep the test free from distraction and bias caused by such observers. The panel further agreed with the trial court’s conclusion that forcing Dr. Malatesta to conduct the examination' in the presence of counsel would place him at odds with his ethical duties.

Finally, the Superior Court also concurred with the trial court’s concern that permitting a third-party observer into the examination room would afford Appellants’ counsel an ‘‘irrefutable impeachment tool,” and, given the potential that tests conducted with a third-party observer might not yield a valid result, the doctor’s own statements could be used for impeachment if the court forced him to conduct his examination in the presence of a third party against his will. Shearer, 135 A.3d at 644. Noting that the concerns expressed by the doctor and the trial court were neither abstract nor unsubstantiated, the court concluded that the trial court’s proposed resolution — permitting Appellants’ counsel to be present during Mrs. Shearer’s preliminary interview, but not during the standardized testing portion of the exam-represented a thoughtful balance of’ the patient’s interest in the presence of counsel, and the court’s obligation to prevent abuse of the discovery process.

Appellants filed a petition for allowance of appeal with our Court, and we granted allocatur to address (1) whether Mrs. Shearer has the right to have counsel present and to audio record the defense’s neu-ropsychological examination of her pursuant to Pa.R.C.P, 4010; and (2) whether the trial court properly granted a protective order excluding counsel and the recording of the standardized portion of the examination. We also instructed the parties to address whether the Superior Court erred in holding the appeal was properly before our Court under the collateral order doctrine pursuant to Pa.R.A.P. 313. Shearer v. Hafer, 157 A.3d 477 (Pa. 2016) (order).

As it is a threshold inquiry, we first address the propriety of appellate review under the collateral order doctrine. Whether an order is appealable under the collateral order doctrine under Pa.R.A.P. 313 is a question of law, subject to a de novo standard of review, and the scope of review is plenary. Rae v. Pa. Funeral Director’s Association, 602 Pa. 65, 977 A.2d 1121, 1126 n.8 (2009).

Appellants contend that the trial court’s order is reviewable as a collateral order under Pa.RA.P. 313. First, Appellants claim that the order is separable from and collateral to the main cause of action, as the order at issue — a non-party defense examiner’s claim that counsel may not be present during certain portions of his’examination — is clearly separable from Mrs. Shearer’s negligence claim. As to the second prong, Appellants argue that the ability of an injured plaintiff to have counsel present and to record all portions of a defense neuropsychological examination is too important to be denied review as it has not been previously considered by an appellate court, implicates a right deeply rooted in public policy beyond the litigants, and outweighs any efficiency interest in discouraging piecemeal litigation. Finally, as to the third prong, Appellants argue that compelling a psychological examination would render the claim irreparably lost, as, once the examination is conducted, Mrs. Shearer’s protections under Rule 4010 would be gone, and, according to Appellants, no subsequent relief could be afforded.

For their part, Appellees offer that, generally, discovery orders are interlocutory, and they note that they initially questioned the Superior - Court’s jurisdiction in this matter. However,' Appellees now agree with Appellant that the issues regarding a party’s right to counsel during a medical examination under Pa.R.C.P 4010 and 4012 were properly before the Superior Court pursuant to Pa.R.A.P. 313. '

While the parties agree that the underlying issues satisfy Rule 313, and that the current appeal is properly before our Court, the question of whether the collateral order doctrine has been met is jurisdictional in nature. Therefore, we must independently consider whether the collateral order doctrine has been satisfied. See Dougherty, 138 A.3d at 627 n.9 (noting “jurisdictional dynamic” of collateral order doctrine insulating issue from waiver, and finding issue “within the scope of appropriate sua sponte judicial review”); Commonwealth v. Blystone, 632 Pa. 260, 119 A.3d 306, 311 (2015) (“Although the Commonwealth has not raised a question regarding our jurisdiction over the trial court’s interlocutory order ... we may nevertheless raise the issue of jurisdiction sua sponte.").

We first consider the evolution of the final order rule and the collateral order doctrine in the federal and state systems. Generally speaking, an appellate court’s jurisdiction extends only to review of final orders. See Pa.R.A.P. 341 (“[A]n appeal may be' taken as of right from any final order.”). The'final order rule reflects the long-held limitation on review by both federal and state appellate courts. Considering issues only after a final order maintains distinctions between trial and appellate review, respects- the traditional role of the trial judge, and promotes formality, completeness, and efficiency. See generally Michael E. Harriss, Rebutting the Roberts Court: Reinventing the Collateral Order Doctrine Through Judicial Decision-Making, 91 Wash. U. L. Rev. 721, 725 (2014) (“Preventing piecemeal litigation is often seen as a means of promoting judicial efficiency and respecting the traditional role of the trial judge. According to this rationale, the cost of a wrong, decision by a trial judge is typically outweighed by either the benefit provided by uninterrupted trial proceedings or the assurance, that the issue is adequately reviewable through alternatives to an immediate appeal.”); Riyaz A. Kanji, The Proper Scope of Pendent Appellate Jurisdiction in the Collateral Order Context, 100 Yale L.J. 511, 512-13 (1990) (offering that the final order rule “serves to maintain the appropriate relationship between the district and appellate courts ... by ensuring that [trial judges’] every determination is hot subject to the immediate review of an appellate tribunal ' .... The consolidation of all contested rulings into a single appeal provides the circuit courts with an opportunity, furthermore, to consider atrial judge’s actions in light of the entire proceedings below, thereby enhancing the likelihood of sound appellate review.”). Further, the United States- Supreme Court has suggested that allowing non-final orders to be immediately appeal-able could be used as a tool of harass-, ment, by extending the litigation process and increasing the opposing party’s expenses. Cobbledick v. United States, 309 U.S. 323, 325, 60 S.Ct. 540, 84 L.Ed. 783 (1940). In Pennsylvania, final orders are those which (1) dispose of all claims and all parties, (2) are explicitly. defined as: final orders by statute, or (3) are certified as final orders by the trial court or other reviewing body. See Pa.R.A.P. 341.

■However, recognizing the harshness of the final order rule in certain circumstances, Justice Jackson,, writing for the United States Supreme Court in Cohen v. Beneficial Industrial Loan Corp., 337 U.S. 541, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949), explicitly recognized an exception to the rule through the collateral order doctrine, which permitted the appeal of a narrow class of orders which address claims of right “separable from, and collateral to, rights asserted in the action, too important to be denied review and too independent-of the cause [of action] itself to require that appellate consideration be deferred until the whole case is adjudicated.” Id. at 546, 69 S.Ct. 1221.

Approximately 25 years later, in Bell v. Beneficial Consumer Discount Co., our Court embraced the collateral order doctrine as a matter of Pennsylvania law, finding “a pre-trial order dismissing the class aspects of a suit, but allowing the case to proceed as an individual action, is an appealable final order.” 465 Pa. 225, 348 A.2d 734, 734 (1975). Shortly thereafter, the Court followed the United States Supreme Court, embracing a “practical rather than a technical construction” of what constitutes an appealable order, adopting the three-part federal formulation, and, thus, permitting immediate appellate review of certain collateral orders. Pugar v. Greco, 483 Pa. 68, 394 A.2d 542, 545 (1978) (quoting Cohen, supra). Over the subsequent 15 years, Pennsylvania’s intermediate courts expressed a “need for clarification and reform” in the area, resulting in the 1992 adoption of Rule of Appellate Procedure 313. Bollinger v. Obrecht, 122 Pa.Cmwlth. 562, 552 A.2d 359, 360 n.2 (1989); see generally Carl A. Solano and Bruce P.. Merenstein, Interim Issues Requiring Appellate Review — Pennsylvania’s Collateral Order Doctrine: Lessons From., the Barnes Foundation Case and the 30 Years of Jurisprudence Preceding It, 77 Pa. Bar Assn. Quarterly 145 (Oct. 2006).

Rule 313 provides,, in pertinent part:

(a) General rule. An appeal may be taken as of right from a collateral order of an administrative agency or lower court. . .

(b) Definition. A collateral order is an order [1] separable from and collateral to the main cause of action where [2] the right involved is too important to be denied review and [3] the question presented is such that if review is postponed until final judgment in the case, the claim will be irreparably lost.

Pa.R.A.P.' 313 (numerical listing added). Accordingly, where an order satisfies Rule 313’s three-pronged test, an appellate court' may exercise jurisdiction even though the order is not final. If the test is no't met, however, and in the absence of another exception to the final órder rule, there is no jurisdiction to consider an appeal of such an order. See Commonwealth v. Kennedy, 583 Pa. 208, 876 A.2d 939, 943, (2005) (finding a Rule 313 issue is “an issue of [an appellate court’s] jurisdiction to entertain an appeal”).

More recently, however, and in response to perceived overly-generous use of the collateral order doctrine by federal intermediate courts, the United. States Supreme Court began imposing “severe limitations” on the'ability of litigants to be granted review of a non-final order. ^[3] For example, in Coopers & Lybrand v. Livesay, 437 U.S. 463, 98 S.Ct. 2454, 57 L.Ed.2d 351 (1978), the Court rejected the determination by the United States Court of Appeals for the Second Circuit that a denial of class certification justified .collateral review. The Court reasoned, inter alia, that the factual issues underlying the denial of certification were enmeshed with the merits of the underlying litigation and the decision could be effectively reviewed after final judgment. Id. at 468-69, 98 S.Ct. 2454; see also Digital Equip. Corp. v. Desktop Direct, Inc., 511 U.S. 863, 114 S.Ct. 1992, 128 L.Ed.2d 842 (1994) (holding the federal collateral order doctrine must be interpreted narrowly). Consistent with this bounded approach to the collateral order doctrine, in 2009, the high Court, focusing solely on the third , prong of the collateral order analysis, determined that a ruling regarding the- disclosure of certain materials putatively protected by the attorney-client privilege was hot eligible for collateral order appeal, as such orders were reviewable after a final judgment in the matter, and, thus, not irreparably lost as to justify collateral order review. Mohawk Industries, Inc. v. Carpenter, 558 U.S. 100, 108-09, 130 S.Ct. 599, 175 L.Ed.2d 458 (2009).

Our Court, however, recognizing that the Mohawk decision was at odds with our own jurisprudence, declined to follow, the federal approach. Commonwealth v. Harris, 612 Pa. 576, 32 A.3d 243 (2011). Respectfully disagreeing with the- ‘high Court’s decision in Mohawk, our Court reasoned that, once disclosed, privileged material can be repeated to others, losing its confidentiality. As we explained, “the bell has been rung,- and cannot be unrung by a later appeal.” Id. 32 A.3d at 249.

Additionally, as set forth in Harris, our Court embraced a more category-wide approach to discovery orders that are alleged to violate the attorney-client privilege or the work product doctrine. See id.; see also Commonwealth v. Williams, 624 Pa. 405, 86 A.3d 771, 780 (2014); Commonwealth v. Dennis, 580 Pa. 95, 859 A.2d 1270, 1278. (2004). Indeed, the Harris Court broadly stated that “orders overruling claims of privilege and requiring disclosure are immediately appealable under Pa.R.A.P. 313.” 32 A.3d at 251.

Nevertheless, Harris’ categorical approach must be tempered by an appreciation that the collateral order doctrine is to be narrowly construed in order to buttress the final order doctrine, and by the recognition that a party may seek an interlocutory appeal by permission pursuant to Pa. R.A.P. 312. ^[4] See Williams, 86 A.3d at 780; Rae, 977 A.2d at 1126. Thus, even post-Harris, in cases where the propriety of an appeal involving the attorney-client privilege or the work product doctrine is contested, we have still required the appealing party to establish each of the three prongs of the collateral order test to ensure that Rule 313 has been satisfied. Dougherty, 138 A.3d at 628-29; Commonwealth v. Flor, 635 Pa. 314, 136 A.3d 150, 155-56 (2016).

In sum, then, while our Court has diverged from the federal approach in some regards, we nonetheless construe the collateral order doctrine narrowly, and insist that each one of its three prongs be “clearly present” before collateral appellate review is allowed. Melvin v. Doe, 575 Pa. 264, 836 A.2d 42, 47 (2003); Geniviva v. Frisk, 555 Pa. 589, 725 A.2d 1209, 1214 (1999). Indeed, “[w]e construe the collateral order doctrine narrowly so as to avoid ‘undue corrosion of the final order rule,’ ... and to prevent delay resulting from ‘piecemeal review of trial court decisions.’ ” K.C. v. L.A., 633 Pa. 722, 128 A.3d 774, 778 (2015) (quoting Pridgen v. Parker Hannifin Corp., 588 Pa. 405, 905 A.2d 422, 427 (2006)). As colorfully explained by then-Justiee, later Chief Justice, Henry X. O’Brien, “[i]t is more important to prevent the chaos inherent in bifurcated, trifurcat-ed, and multifurcated appeals than it is to correct each mistake of a trial court the moment it occurs.” Calabrese v. Collier Township Municipal Authority, 432 Pa. 360, 248 A.2d 236, 238 (1968) (O’Brien, J., dissenting). Moreover, as parties may seek allowance of appeal from an interlocutory order by permission, we have concluded that that discretionary process would be undermined by an overly permissive interpretation of Rule 313. Geniviva, 725 A.2d at 1214 n.5.

With this background in mind, we turn to application of the three-prong collateral order test in this appeal. As noted above, the collateral order doctrine permits an appeal as of right from a non-final collateral order if the order satisfies the three requirements set forth in Rule 313(b) — separability, importance, and irre-parability.

With regard to the first prong of the collateral order doctrine, an order is separable from the main cause of action if “it can be resolved without an analysis of the merits of the underlying dispute” and if it is “entirely distinct from the underlying issue in the case.” Blystone, 119 A.3d at 312 (internal quotation marks omitted). The discovery-based issue of whether a plaintiff in a civil personal injury action has the right to counsel or other representative during a neuropsychological examination is a distinct legal question which has no bearing on the underlying issues in this negligence action. Consequently, we find that Appellants have established that the trial court’s order is separable from the main cause of action, and, thus, have satisfied the first prong of the collateral order doctrine.

Turning to the second prong of the collateral order doctrine, the importance prong, a right is important if “the interests that would go unprotected without immediate appeal are significant relative to the efficiency interests served by the final order rule.” Williams, 86 A.3d at 782. Ftír-ther, the rights involved must implicate interests “deeply rooted in public policy [and] going beyond the particular litigation at hand.” Blystone, 119 A.3d at 312 (internal quotation marks omitted).

We find that Appellants’ appeal does not satisfy this prong. First, the right to counsel in this instance does not implicate a constitutional .right, but, rather, is rule-based. Indeed, Appellants’ counsel at oral argument confirmed that the issue before us is not constitutional in nature. Additionally, the right asserted is not solely one implicating legal representation, as the rule provides that counsel “or other representative” may be present during an examination. Pa.R.C.P. 4010(a)(4). -Indeed, at oral argument, Appellants’ counsel explained that his practice was-to have a nurse attend such examinations, thereby eliminating the potentiality of counsel having to testify at trial as a witness. ^[5] Finally, it appears that only a discrete part of the broader .psychological examination is at issue, as Dr. Malatesta indicated he would allow Appellants’ representative to be present during the interview portion of the evaluation, and would only preclude a representative at, or taping of, the standardized testing phase of his examination, and the trial court so ordered.

Rather than concerning a constitutional, per se, right to an attorney, the issue before our Court involves counsel and layperson representation, and is largely limited, individualized, and fact-based. Thus, we find that, while the contours of a right to representation during certain aspects of a neuropsychological evaluation give rise to a significant question, it is not of the magnitude of those issues-which are “deeply rooted in public policy going beyond the particular litigation at hand.” Blystone, 119 A.3d at 312. ^[6] Therefore, we find that Appellants have not satisfied the importance prong of the collateral order doctrine. ^[7]

Lastly, even if we were to' determine that Appellants satisfied the second prong, we conclude that Appellants’ claimed right to the presence of counsel or a representative at the standardized portion of a neu-ropsychological evaluation will not be irreparably lost if review is postponed until after final judgment, and, thus, that Appellants have failed to establish the third prong of the collateral order doctrine. Specifically,. Appellants seek to have counsel or a representative present at any examination and claim the proverbial “bell cannot be unrung” such that relief would not be available after final judgment. We disagree.

If Mrs. Shearer is examined by Dr. Ma-latesta per the trial court’s ruling — -with representation during the interview portion of the neuropsychology examination, but not during the standardized testing phase of his evaluation, and without recording — and, subsequently on appeal, it is determined that she was legally entitled to the presence of a representative or the audiotaping of the entire evaluation, then a new trial could be awarded, and a new standardized test examination could be conducted with such representation and/or recording. The results of and any information obtained during, or derived from, the first unrepresented standardized testing, if found to be objectionable or prejudicial, could be excluded in toto for purposes of the new trial. See, e.g., Vaccone v. Syken, 587 Pa. 380, 899 A.2d 1103, 1107 (2006) (finding “orders disqualifying counsel in civil cases are not collateral orders subject to appeal”), superseded on other grounds by Pa.R.A.P. 1114(b)(7); Commonwealth v. Wells, 553 Pa. 424, 719 A.2d 729, 731 (1998) (determining criminal defendant’s appeal of trial court’s denial of counsel’s petition to withdraw due to an alleged conflict' of interest did not satisfy collateral order doctrine as defendant could be granted a new trial and new counsel on appeal). Indeed, Appellants offer no example of information or other matters that could not, in this fashion, be “unrung.’■’ Nor do they not contend that Mrs. Shearer would suffer any specific harm by taking the standardized portion of neuropsycho-logical examination ivithout the presence of counsel or- other représentative, which is the relevant focus. Rather, they simply assert that, if not permitted an interlocutory appeal, she would have to retake what could be a lengthy standardized examination; yet, this is the type of inconvenience which, any litigant might suffer if they prevail on appeal-and are, for. example, granted a new trial. Thus, in our view, the rights that Appellants now assert, unlike privileges or immunities, are not irreparably lost if we do not allow an immediate interlocutory appeal in. this matter. ^[8] Accordingly, we find that Appellants have not met the third prong of the collateral order test. ^[9]

As Appellants have not satisfied .the second and third prongs of the collateral order doctrine, and, as each and every prong must be “clearly present,” we find that the requirements of the. collateral order doctrine are not met. Thus, we conclude that the trial court’s order disallowing representation during the standardized portion of the neuropsychological examination was not an appealable collateral order as of right under Rule 313 and, consequently, that the Superior Court erred in considering Appellants’ appeal. As a result, we do not reach the merits of the underlying issues on which we granted allocatur; rather, the order of the Superior Court is vacated, the present appeal is quashed as an unauthorized interlocutory appeal, and the matter is remanded to the Lebanon County Court of Common Pleas for further-proceedings.

Jurisdiction relinquished.

- Chief Justice Saylor and Justices Baer, Donohue, Dougherty and Wecht join the opinion.

Justice Wecht files a concurring opinion.

Justice Mundy files a dissenting opinion.

I join the learned Majority in full. I write separately to express concerns regarding some aspects of this case.

The trial court issued a protective order disallowing Appellants’ counsel or representative from attending the standardized testing based upon Pa.R.C.P. 4012’s grant of authority to a trial court to enter protective orders as justice requires when good cause is shown. The trial court’s determination that Appellees showed good cause was based, in part, upon the ethical grounds that Dr. Malatesta asserted. I express no judgment on the -merits of the trial court’s finding. Nonetheless, I would caution courts to subject such claims to careful scrutiny. ^[1] Otherwise,. expert witnesses,-rather than judges, will define the scope and process of discovery. .

Relatedly, I detect a palpable risk that reliance upon standards written by nongovernmental Organizations, such as the APA and NAN in this case, may run afoul of the non-delegation doctrine. Dr. Ma-latesta was concerned about the APA guidelines, not only for their ethical implications, but because the Commonwealth of Pennsylvania’s State Board of Psychology has made compliance with the APA’s ethical guidelines and code of conduct mandatory by incorporating those provisions into its Code of Ethics. See 49 Pa. Code— 41.61(3)(e). Non-compliance is grounds for disciplinary action. See 63 Pa.C.S.— 1208(a)(9); Brief of Appellees at 30; Ami-cus Brief of the Pennsylvania Psychological Association at 16-18.

The General Assembly may authorize a board to develop ethical guidelines or codes. See Pa. State Assoc. of Twp. Supervisors v. Thornburgh, 45 Pa.Cmwlth. 361, 405 A.2d 614, 617 (1979). However, the General Assembly or the Board may not delegate that responsibility to a third party without providing clear guidelines. See State Bd. of Chiropractic Examiners v. Life Fellowship, 441 Pa. 293, 272 A.2d 478, 481 (1971); see also Protz v. W.C.A.B. (Derry Area Sch. Dist.), 161 A.3d 827, 835 (Pa. 2017) (holding that statute designating the “most recent edition” of the American Medical Association guide as the source for determining percentage of disability for workers’ compensation purposes was an impermissible delegation because the legislature did not set any particular policy or “prescribe any standards to guide and restrain the AMA’s discretion”). While we have neither the record nor the advocacy in this case to resolve the delegation issue or even reach its merits, boards and agencies should be cognizant of the issue and should attend diligently to its implications. ^[2]

I agree with the Majority that the re-viewability of the issues in this case turns on the application of the collateral order doctrine. Further, I take no issue with its discussion of the historical development balancing the competing policy concerns of the final order and collateral order doctrines. Where I differ is in the Majority’s application of that balance as reflected in Pennsylvania Rule of Appellate Procedure 313(b) to the order in this case.

I agree with the Majority that the order is separable from the main cause of action. However, I depart from the Majority’s discussion of the second prong of the collateral order doctrine, that is, whether the right affected by the order at issue is “too important to be denied review.” Pa.R.A.P. 313(b), The Majority correctly identifies the criteria our courts apply when addressing this prong.

[Relative to] the importance prong, a right is important if “the interests that would go unprotected without immediate appeal are significant relative to the efficiency interests served by the final order rule.” [Commonwealth v.] Williams, [624 Pa. 405] 86 A.3d [771,] 782 [ (Pa. 2014) ]. Further, the rights involved must implicate interests “deeply rooted in public policy [and] going beyond the particular litigation at hand.” [Commonwealth v.] Blystone, [632 Pa. 260] 119 A.3d [306,] 312 [(Pa. 2015)] (internal quotation marks omitted).”

Majority Opinion at 858-59.

The Majority Opinion goes on to emphasize that the right at issue in this case is not constitutionally derived, but the product of a rule. Id. at 859. This distinction should not be interpreted as being part of the above-quoted standard. Rule-based rights may well be significant relative to the final order rule and be deeply rooted in public policy. See Ben v. Schwartz, 556 Pa. 475, 729 A.2d 547, 552 (1999) (recognizing issues pertaining to disclosure of privileged information as important for collateral order doctrine purposes); Spanier v. Freeh, 95 A.3d 342, 346 (Pa. Super. 2014) (recognizing right to remove a case to federal court as important for collateral order doctrine purposes). Contrastingly, constitutionally-derived rights, in certain contexts, may not meet the standard. For example, suppression issues in criminal cases, often based on alleged violations of constitutional rights, are generally not deemed to extend beyond the particular facts of the case, or to overcome the policies underlying the final order doctrine. It is not the source of the right but the effect an order denying that right may have on our system of justice and issues deeply rooted in public policy that matters.

Like the Superior Court, I deem the right to counsel, including the right afforded by Rule 4010(a)(4)(i), to be “undeniably too important to be denied review.” Shearer v. Hafer, 135 A.3d 637, 642 (Pa. Super. 2016). The Majority discounts the significance of the right afforded because the Rule also authorizes the presence of a representative in lieu of counsel. However, that choice belongs to the party subject to the neuropsychological evaluation. The fact that a right may potentially be waived to avail oneself of an alternative, does not, in my view, implicate the importance of the right in the first instance.

I also disagree with the Majority’s conclusion that Appellants’ claim will not be irreparably lost. The Majority concludes that if the standardized portion of the evaluation proceeds unrecorded and without presence of counsel, and it is later determined such exclusion was error, Appellant could be granted a new trial where a new examination in compliance with Rule 4010(a)(4)(i) could be performed, and any use of the noncompliant evaluation excluded. The relevance of a medical or neurop-sychological evaluation to issues in an underlying litigation may well be dependent upon when the examination takes place. The passage of time may result in an inability to adequately measure or ascertain the pertinent conditions, deficiencies, or diagnoses, resulting in a loss of the benefit from a properly and timely conducted evaluation. In this sense, the Superior Court’s reliance on our decision in Commonwealth v. Shearer, 584 Pa. 134, 882 A.2d 462 (2005) is apt. In Shearer, the concern was over a trial court order compelling a psychological examination of a minor victim in a criminal case and the attendant right to privacy implicated thereby. We found that deferring review of the order would result in the underlying claim being lost with no way to “turn back the clock” if it was later determined that the examination should not have been ordered. Shearer, 882 A.2d at 469. Similarly, there will be no way to turn back the clock and conduct a timely evaluation with a representative present if review of the issue is deferred until the appellate stage of the underlying trial matter. ^[1]

For these reasons, I conclude the third prong of Rule 313 has been met- in this case, and I would proceed to address the merits.
