Modifier -59 Comes in Handy for Multiple Excisions

Question: The dermatologist excised two sebaceous cysts from the patient's back. One cyst measured 4.7 cm and the other was 3.3 cm. How should I code this?

Answer: For the 4.7-cm cyst excision, you should report 11406 (Excision, benign lesion including margins, except skin tag [unless listed elsewhere], trunk, arms or legs; excised diameter over 4.0 cm). You should report 11404-59 (... excised diameter 3.1. to 4.0 cm; distinct procedural service) for your dermatologist's removal of the 3.3-cm cyst.

Both 11406 and 11404 are appropriate for three reasons: 
 

  • the lesions were benign
     
  • they were located on the patient's "trunk"
     
  • the cysts' measurements match the specified lesion diameters in the codes' descriptors.

    You need to attach modifier -59 (Distinct procedural service) to 11404 to show the insurer that the second excision was separate and distinct from the first procedure.
