Like most health insurance, Medicare covers a variety of preventive care services. The reason? Preventive care is less expensive than treatment. Luckily, what's good for Medicare's bottom line is also good for your health.

This page looks at the most common preventive care services covered by Medicare. For a complete list, please see the Medicare site. 

Welcome to Medicare Preventive Visit and Yearly Wellness Exam

Once you sign up for Medicare Part B, you are eligible for the Welcome to Medicare preventive visit. Assuming your provider accepts assignment, your out-of-pocket cost for this service is zero. 

This screening gives your doctor a baseline reading of your current health. Your provider measures a variety of vitals, including height, weight, and blood pressure. They also take a complete medical history and discuss behavioral health issues. The screening also includes a basic vision test and a body mass index calculation. 

Your doctor should also offer flu and pneumococcal shots if appropriate and explain advance directives. The visit should end with a written plan that lists other preventive screenings your doctor recommends. 

After your first 12 months, Part B covers a Yearly Wellness Exam. This is essentially the same visit and, again, your out-of-pocket cost is zero. Medicare covers this visit every 12 months. 

Cancer Screenings Covered by Medicare

Medicare Part B covers numerous cancer screenings, including:

• Colorectal cancer screenings, including multi-target stool DNA test, fecal occult blood test, colonoscopy, and barium enema 
• Lung cancer screenings for qualified patients 
• Mammograms 
• Pap test
• Pelvic exam, including clinical breast exam 
• Prostate cancer screenings, including digital rectal exam and prostate specific antigen blood test 

Patients may need to meet certain criteria regarding age and health status. For example, to qualify for the lung cancer screening, you must be aged 50 to 77 and have smoked an average of one pack per day for 30 years. Out-of-pocket costs vary, from zero to the standard co-insurance amount of 20 percent. Frequency of the screening varies as well. 

Screenings for Chronic Conditions

Chronic conditions are much easier to treat if you catch them early. In fact, you may be able to avoid them altogether.
