Me. Rev. Stat. tit. 24-A, § 2436 (2026)

1.  A claim for payment of benefits under a policy or certificate of insurance delivered or issued for delivery in this State is payable within 30 days after proof of loss is received by the insurer and ascertainment of the loss is made either by written agreement between the insurer and the insured or beneficiary or by filing with the insured or beneficiary of an award by arbitrators as provided for in the policy. For purposes of this section, "insured or beneficiary" includes a person to whom benefits have been assigned. A claim that is neither disputed nor paid within 30 days is overdue. If, during the 30 days, the insurer, in writing, notifies the insured or beneficiary that reasonable additional information is required, the undisputed claim is not overdue until 30 days following receipt by the insurer of the additional required information; except that:  

1-A.  A claimant, including a health care provider, may submit simultaneously a claim for payment with all carriers potentially liable for payment of the claim whether primary or secondary. Payment or denial of a claim by each carrier must be made within 30 calendar days after the carrier has received all information needed to pay or deny the claim whether or not another carrier with which it is attempting to coordinate has acted on the claim. Upon request by a health care provider, a carrier shall provide the health care provider a method for making a claims payment using an electronic funds transfer through the automated clearinghouse network. Any payment made must be in accordance with rules adopted by the superintendent relative to coordination of benefits. For the purposes of this subsection, "health care provider" includes a person licensed to provide dental care services under Title 32, chapter 143, subchapter 3 and "carrier" includes an insurer that provides dental insurance.  

2.  An insurer may dispute a claim by furnishing to the insured or beneficiary, or a representative of the insured or beneficiary, a written statement that the claim is disputed with a statement of the grounds upon which it is disputed. The statement must be based upon a reasonable investigation of the claim and must include sufficient detail to permit the insured or beneficiary to understand and respond to the insurer's position. For purposes of this subsection, a claim for payments under a policy or certificate providing health care coverage is disputed if the insurer has denied the claim or has requested further information that is consistent with Bureau of Insurance Rule Chapter 850.  

2-A.  For a claim submitted by a health care provider or health care facility with respect to a carrier as defined in section 4301‑A, subsection 3, for purposes of this section, a timely claim for payment of covered health care expenses must be submitted to a carrier in conformity with the requirements for standardized claim forms set forth in section 2753.  

2-B.  If a claim does not conform to the requirements specified in subsections 2‑A and 2‑C and payment is denied to a health care provider or health care facility by a carrier, the health care provider or health care facility may not request payment from the insured or beneficiary and shall attempt to rectify the deficiencies with the claim and resubmit the claim to the carrier.  

2-C.  For a claim submitted by a health care provider or health care facility with respect to a carrier as defined in section 4301‑A, subsection 3, for purposes of this section, "undisputed claim" means a manually or electronically submitted claim from a health care provider or health care facility that:  

3.  If an insurer fails to pay an undisputed claim or any undisputed part of the claim when due, the amount of the overdue claim or part of the claim bears interest at the rate of 1 1/2% per month after the due date. Notwithstanding this subsection, the superintendent shall adopt rules that establish a minimum amount of interest payable on an overdue undisputed claim to a health care provider before a payment must be issued. Rules adopted pursuant to this subsection are routine technical rules as defined in Title 5, chapter 375, subchapter 2‑A.  

4.  A reasonable attorney's fee for advising and representing a claimant on an overdue claim or action for an overdue claim must be paid by the insurer if overdue benefits are recovered in an action against the insurer or if overdue benefits are paid after receipt of notice of the attorney's representation.  

5.  Nothing in this section prohibits or limits any claim or action for a claim that the claimant has against the insurer.  

6.  This section does not apply to a claim for payment of benefits under a policy or certificate of long-term care insurance delivered or issued for delivery in this State.
