It’s one of Medicare’s most confusing—and expensive—rules. You can be lying in a hospital bed for days, hooked up to monitors, receiving tests and treatment, yet still not be considered an “inpatient.” That tiny distinction between observation and inpatient status can decide whether Medicare—and your Medigap plan—pays for your next level of care. For thousands of retirees, this technical label has led to unexpected bills of thousands of dollars for skilled nursing stays they assumed were covered. Understanding this rule before it happens could save you a small fortune.
