Improving Access to Medicare Coverage Act of 2023

This bill changes how Medicare counts hospital stays for coverage of skilled nursing care. It treats time spent in outpatient observation (not admitted as an inpatient) as part of the required 3-day inpatient hospital stay. This means beneficiaries who received outpatient observation services will have that time counted toward the 3-day requirement, potentially making them eligible for skilled nursing facility coverage they might otherwise have lost. The change applies to services beginning January 1, 2024, with limited retroactive appeal options for services completed before the law's enactment. It directly affects Medicare beneficiaries needing skilled nursing care after hospital treatment.
