It is apparent that preventive care will take on greater importance in the "reformed " health care system and while Medicare historically did not cover routine or preventive screening services, the list of preventive services now covered by Medicare has grown in recent years.  Physicians should familiarize themselves with the applicable coverage and billing rules so as not to miss an opportunity to capture revenue for these services where appropriate.  To help physicians in this regard, CMS has published a guide to preventive and screening services for physicians and other providers.  Also, for a good overview on the OIG’s current thinking on offering free screening services, physicians and other providers should have a look at the recent OIG Advisory Opinion 09-11 addressing free blood pressure screenings to walk-in visitors at a hospital.
