Calculating an enrollee's cost-sharing obligation for

prescription drug coverage. A. When calculating an enrollee's cost-sharing obligation for covered prescription drugs, pursuant to group health coverage, including any form of self-insurance, offered, issued or renewed under the Health Care Purchasing Act, the insurer shall credit the enrollee for the full value of any discounts provided or payments made by third parties at the time of the prescription drug claim. B. Beginning on or after January 1, 2024, an insurer shall not charge a different cost-sharing amount for: (1) prescription drugs or pharmacy services obtained at a non-affiliated pharmacy; or (2) administration of prescription drugs at different infusion sites; provided that an insurer may communicate with an insured regarding lower-cost sites of service. C. Beginning on or after January 1, 2024, an insurer shall not require an insured to make a payment at the point of sale for a covered prescription drug in an amount greater than the least of the: (1) applicable cost-sharing amount for the prescription drug; (2) amount an insured would pay for the prescription drug if the insured purchased the prescription drug without using a health benefits plan or any other source of prescription drug benefits or discounts; (3) total amount the pharmacy will be reimbursed for the prescription drug from the insurer, including the cost-sharing amount paid by an insurer; or (4) value of the rebate from the manufacturer provided to the insurer or its pharmacy benefits manager for the prescribed drug. D. Beginning on or after January 1, 2024, if a prescription drug rebate is more than the amount needed to reduce the insured's copayment to zero on a particular drug, the remainder shall be credited to the insurer. E. Beginning on or after January 1, 2024, any rebate amount shall be counted toward the insured's out-of-pocket prescription drug costs. F. For purposes of this section, "cost sharing" means any: (1) copayment; (2) coinsurance; (3) deductible; (4) out-of-pocket maximum amount; (5) other financial obligation, other than a premium or share of a premium; or (6) combination thereof. G. The provisions of this section do not apply to excepted benefit plans as provided pursuant to the Short-Term Health Plan and Excepted Benefit Act [Chapter 59A, Article 23G NMSA 1978], catastrophic plans, tax-favored plans or high-deductible health plans with health savings accounts until an eligible insured's deductible has been met, unless otherwise allowed pursuant to federal law.
