Modifier 62



Modifier 62 is used when two surgeons (each in a different specialty) are working together as primary surgeons to perform distinct parts of a single reportable procedure/surgery simultaneously.

Correct Use

  • Append to each Method II Critical Access Hospital (CAH) procedure code line on type of bill (TOB) 85X
  • Append when both surgeons have not signed billing rights to CAH
    • One surgeon will bill procedure code, with modifier 62, on 85X TOB
    • Other surgeon will bill procedure code to Part B on a CMS-1500 Claim Form with 62 modifier

Incorrect Use

  • Do not forget to append this modifier. If left off, Medicare will allow one surgeon at 100% and will deny the other surgeon's claim.
