Other Factors to Consider When Choosing Between -52 and -53

In addition to asking "Why did the physician halt the service?" consider these two questions when selecting between modifiers -52 (Reduced services) and -53 (Discontinued procedure).

  • Did the patient receive anesthesia (if applicable) prior to the discontinuance of the procedure? If no, choose modifier -52. If yes, choose modifier -53.

  • Did the patient receive any benefit from the "partial" procedure? If yes, select modifier -52. If no, select modifier -53.
