(a) As used in this section:

(b) A health insurance entity offering employer-based plans must offer to employers no less than one (1) plan option in which the copayment and coinsurance amounts for services rendered during an office visit to a chiropractic physician licensed under title 63, chapter 4, or to a physical therapist or occupational therapist licensed under title 63, chapter 13, are no greater than the copayment and coinsurance amounts for the services rendered during an office visit to a primary care physician licensed under title 63, chapter 6 or title 63, chapter 9.

(c) Compliance with this section shall not be required with respect to a particular insurance plan if it is determined that compliance would cause that plan to lose its status as a grandfathered health plan within the meaning of § 1251 of the federal Patient Protection and Affordable Care Act, P.L. 111-148, as amended, and § 2301 of the federal Health Care and Education Reconciliation Act of 2010, P.L. 111-152, as amended, both compiled in 42 U.S.C. § 18011.
