To use modifier -59 (Distinct procedural service), make sure the incident meets three key components of the modifier's definition.

First, the modifier is intended to describe separate, distinct procedures or services that are performed on the same day by the same physician, says John Lavere, MBA, CPC, director of compliance for Charlotte Eye Ear Nose & Throat Associates in North Carolina.
