Take this new checklist to your doctor or other health care provider to find out what preventive services are right for you. This comprehensive check-list spells out the Medicare covered preventive services and allows you to keep track of when you received a particular test, screening, or service, as well as when you are due for your next one. Thanks to the Affordable Care Act, these preventive services ranging from mammograms and flu shots to a yearly “wellness” visit, are offered free of charge to patients covered by Medicare.
