45 C.F.R. § 155.1045

(a) Timeline. The Exchange must establish a uniform period following certification of a QHP within which a QHP issuer that is not already accredited must become accredited as required by § 156.275 of this subchapter, except for multi-state plans. The U.S. Office of Personnel Management will establish the accreditation period for multi-state plans.

(b) Federally-facilitated Exchange. The accreditation timeline used in federally-facilitated Exchanges follows:

(1) During certification for an issuer's initial year of QHP certification (for example, in 2013 for the 2014 coverage year), a QHP issuer without existing commercial, Medicaid, or Exchange health plan accreditation granted by a recognized accrediting entity for the same State in which the issuer is applying to offer coverage must have scheduled or plan to schedule a review of QHP policies and procedures of the applying QHP issuer with a recognized accrediting entity.

(2) Prior to a QHP issuer's second year and third year of QHP certification (for example, in 2014 for the 2015 coverage year and 2015 for the 2016 coverage year), a QHP issuer must be accredited by a recognized accrediting entity on the policies and procedures that are applicable to their Exchange products, or a QHP issuer must have commercial or Medicaid health plan accreditation granted by a recognized accrediting entity for the same State in which the issuer is offering Exchange coverage and the administrative policies and procedures underlying that accreditation must be the same or similar to the administrative policies and procedures used in connection with the QHP.

(3) Prior to the QHP issuer's fourth year of QHP certification and in every subsequent year of certification (for example, in 2016 for the 2017 coverage year and forward), a QHP issuer must be accredited in accordance with § 156.275 of this subchapter.
