In this section, “fertility awareness–based methods” means methods of identifying times of fertility and infertility by an individual to avoid pregnancy, including: cervical mucus methods; sympto–thermal or sympto–hormonal methods; the standard days method; and the lactational amenorrhea method. This section applies to: insurers and nonprofit health service plans that provide hospital, medical, or surgical benefits to individuals or groups on an expense–incurred basis under health insurance policies or contracts that are issued or delivered in the State; and health maintenance organizations that provide hospital, medical, or surgical benefits to individuals or groups under contracts that are issued or delivered in the State. An entity subject to this section shall provide coverage for instruction by a licensed health care provider on fertility awareness–based methods. Except with respect to a health benefit plan that is a grandfathered health plan, as defined in § 1251 of the Affordable Care Act, an entity subject to this section may not apply a copayment, coinsurance requirement, or deductible to the coverage required under this section.
