Which modifier should be used to indicate that a service code was reduced from its original description?

• A. -53
• B. -73
• C. -74
• D. -52

Answer: (D)

When a service is performed but not to its full described scope, you signal that by using the reduced services modifier. This modifier shows the base CPT code is still the right code, but the actual work done was less than what the code’s description covers. It’s used specifically to reflect partial completion of a service due to circumstances, not a complete cancellation or discontinuation of the procedure. The other modifiers you might see are for situations where the procedure is started but not completed or is canceled before or after anesthesia. Those describe discontinuations or cancellations, not a partial reduction in what was performed, so they don’t apply when the provider did perform a service—just to a lesser extent. So, the best choice to indicate that the service code was reduced from its original description is the reduced services modifier.
