The Preserving Patient Access to Long-Term Care Pharmacies Act would temporarily provide additional payments to pharmacies that specialize in long-term care settings for dispensing certain drugs to Medicare patients. Specifically, insurance plans under Medicare's drug coverage program would be required to pay long-term care pharmacies a $30 supply fee per prescription in 2026, with the fee adjusted upward in 2027, on top of existing reimbursements for ingredient costs and dispensing fees. The federal government would then reimburse insurance plans for these supply fees, ensuring plans bear no net cost. The bill includes enforcement penalties of at least $10,000 for plans that fail to pay these fees and requires the Government Accountability Office to study the financial sustainability of long-term care pharmacies in Medicare within 12 months to inform future policy decisions. The temporary measure, if enacted, would apply only to plan years 2026 and 2027.
