Medicare Part A and hospital care
To use a lifetime reserve day, first you must be eligible for inpatient hospital care that is covered by Medicare Part A.
To qualify for inpatient hospital care, your hospital doctor must make an official order stating that “you need 2 or more midnights of medically necessary inpatient hospital care to treat your illness or injury and the hospital formally admits you.” Medicare.gov provides a guide to determine if you are a hospital outpatient or inpatient.
You must use Medicare Part A hospital inpatient services for more than 90 days in a benefit period in order for a Medicare lifetime reserve day to be used.
Inpatient hospital health care costs
The Medicare program will charge you deductibles and co-insurance for Part A inpatient hospital stays and health care costs, including a $816 co-insurance payment per lifetime reserve day in 2024. The table below outlines the 2024 costs associated with inpatient hospital stays.
