From the Medicare Inpatient Hospitals - by Provider and Service (data year 2024): the published hospital-by-DRG averages of Medicare fee-for-service inpatient discharges in 2024. Cells with fewer than 11 discharges are not published, so a hospital with a handful of cases is not counted. Average Medicare payment excludes the patient’s deductible and coinsurance.
