(a) The Department shall, subject to federal approval, mirror the Medical Assistance hospital reimbursement methodology for Affordable Care Act adults who are enrolled under a fee-for-service or capitated managed care program, including hospital access payments as defined in Section 5A-12.2 of this Article and hospital access improvement payments as defined in Section 5A-12.4 of this Article, in compliance with the equivalent rate provisions of the Affordable Care Act.

(b) If the fee-for-service payments authorized under this Section are deemed to be increases to payments for a prior period, the Department shall seek federal approval to issue such increases for the payments made through the period ending on June 30, 2018, or as provided in Section 5A-16, even if such increases are paid out during an extended payment period beyond such date. Payment of such increases beyond such date is subject to federal approval. If the Department receives federal approval of such increases, the Department shall pay such increases on the same schedule as it had used for such payments prior to June 30, 2018.
