Does Medicare cover the new Alzheimer's blood test?
Answer:
Medicare Part B covers certain cognitive assessment services and generally covers medically necessary diagnostic laboratory tests ordered by qualified health care providers. However, FDA clearance does not automatically guarantee Medicare coverage. As of Aug. 25, 2026, LTC News found no CMS coverage determination specifically addressing the newly cleared Elecsys pTau217 test. Patients should check with their doctor, laboratory, and health plan about coverage and possible out-of-pocket costs.
