What is the Medicare Conversion Factor?

The conversion factor is the dollar amount CMS uses to turn a code's total RVUs into a Medicare payment. This page uses the CY 2026 conversion factor of $33.4009. CMS updates it every year in the Physician Fee Schedule final rule.

Facility vs. Non-Facility?

The non-facility rate applies in a physician office, where the practice pays for its own staff, supplies, and equipment, so the rate is usually higher. The facility rate applies in hospital outpatient departments and ASCs, where the facility bills for those costs separately.

How do I decide which administration code to use?

Pick the code that matches the type of drug, the route, and how long the administration takes. Start from the highest-ranking service you performed, then add the appropriate add-on codes for extra time or extra drugs. Manufacturer billing and coding guides often list suggested administration codes.
