Free preventive care under Medicare: what you can get at $0

The preventive services Part B covers with no cost sharing, the difference between a wellness visit and a physical, and how to avoid surprise bills.

Part B covers many preventive services with no deductible and no coinsurance, as long as your provider accepts assignment. Most people use only a fraction of them.

Wellness visit vs physical exam

The Annual Wellness Visit is a planning conversation: health risk assessment, medication review, a personalised prevention plan. It is not a head-to-toe physical. Medicare does not cover routine physical exams. If your doctor examines a new problem during the wellness visit, that part can be billed separately with normal cost sharing.
