What is the Difference Between Preventive Services and Diagnostic Services?Many preventive services are provided with diagnostic treatment or health care services.

A service is considered preventive if you have no prior symptoms. In some cases, Medicare only covers preventive care if you possess certain risk factors.

This is unlike diagnostic services, which address symptoms or conditions you already have. The classification of services as preventive versus diagnostic is important because it affects your out-of-pocket costs.

With diagnostic services, you will typically need to pay a copay, coinsurance, and/or deductible.

The Annual Wellness Visit is a Medicare-covered preventive service that does not require cost sharing. However, if during your wellness visit your provider investigates or treats a symptom you are experiencing, this additional care is not included. Therefore, cost sharing in the form of a coinsurance or copay will apply.
