Inpatient Care

Care you receive when you are formally admitted to a hospital. Medicare Part A covers inpatient hospital care after you meet your deductible. Being in a hospital as an inpatient is different from outpatient observation status, which is covered under Part B.

IRMAA (Income-Related Monthly Adjustment Amount)

An extra amount added to your Part B and Part D premiums if your income is above a certain threshold, based on the tax return from two years earlier. IRMAA is reassessed annually and can be appealed after certain life-changing events like retirement.
