| 59 | Distinct Procedural Service – Under certain circumstances, the physician may need to indicate that a procedure or service was distinct or independent from other services performed on the same day.

This may represent a different session or patient encounter, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same physician. However, when another already established modifier is appropriate it should be used rather than modifier -59. Only if a more descriptive modifier is not available, and the use of modifier –59 best explains the circumstances should modifier -59 be used.

Use only when more than two modifiers are needed to describe a service. No effect on payment; however, the individual modifiers listed will apply, including any potential effect they may on payment. |
