Fam Pract Manag. 2004;11(10):31-32

As a family physician, you probably have a lot of questions about Medicare, the answers to which may affect whether you get paid for your services. The Centers for Medicare & Medicaid Services (CMS) Web site has an amazing number of answers – if you know where to look.

Getting started

The best place to start is the site’s main page at Along the left side of the page, you will find links to each of CMS’s major program areas – such as Medicare, Medicaid, the Health Insurance Portability and Accountability Act (HIPAA) and Clinical Laboratory Improvement Amendments (CLIA) – as well as key topics such as “Coverage” and “Quality Initiatives.” Along the top of the home page, you will find, among other things, a link to a Frequently Asked Questions (FAQ) database and a search feature powered by Google. You’ll also see pulldown menus for various CMS audiences. Under the “Professionals” tab is a link for “Physicians,” which is our next stop on the tour.

Speaking of ABNs, knowing when you need one often depends on knowing whether Medicare covers the service in question and under what conditions. Fortunately, CMS has provided an online, searchable database of both national and local (i.e., carrier-specific) coverage policy.
