Medicare Part A will cover blood tests done as an inpatient in a hospital or skilled nursing or rehab facility, and Part B will cover blood tests done as an outpatient in any setting, when the blood tests are ordered to diagnose or monitor a condition or disease.
Medicare Part A and B does not ordinarily cover routine blood screening. However, some preventative screenings have recently been added to the blood tests that are covered under Medicare part B: diabetes screening for those who are high risk for diabetes, one blood test every 5 years to test cholesterol, HIV tests for those who are high risk or pregnant, and prostate cancer screening yearly.
