Let NCCI Steer Your Modifier -59/-51 Use

Question: When should I use modifier -59 instead of modifier -51?


California Subscriber


Answer: You should use modifier -59 (Distinct procedural service) when the National Correct Coding Initiative bundles the two codes that you are reporting. If the codes are not bundled, report modifier -51 (Multiple procedures).

Warning: Make sure that modifier -59 appropriately describes the relationship between the two procedures and that the edits allow a modifier to override the bundle.

Remember, modifier -59 is not a license to unbundle. You may use modifier -59 only when the circumstances match one of these descriptions:
 

  • different session or patient encounter
     
  • different procedure or surgery
     
  • different site or organ system
     
  • separate incision/excision
     
  • separate lesion
     
  • separate injury.

    Modifier -59 example: An otolaryngologist controls epistaxis in a patient (30903, Control nasal hemorrhage, anterior, complex [extensive cautery and/or packing], any method]). Later the same day, the patient has break-through bleeding, requiring endoscopic hemorrhage control (31238, Nasal/sinus endoscopy, surgical; with control of nasal hemorrhage).

    To override the 30903-31238 bundle, you should append modifier -59 to the bundled procedure - the epistaxis control (30903). The modifier tells the payer that the otolaryngologist performed the hemorrhage control in a separate session from the endoscopic nasal hemorrhage control. Therefore, he deserves payment for the epistaxis control.

    Modifier -51 example: The otolaryngologist excises two lesions from two different locations: one from the vestibule of the mouth, 40810 (Excision of lesion of mucosa and submucosa, vestibule of mouth; without repair), and one from the tongue, 41110.
     
    In this case, you should append modifier -51 (Multiple procedures) to the lesser-valued procedure - 40810. Because you have two separate CPT codes that are not bundled, you can report both codes.

    Exception: Do not automatically use modifier -51 on Medicare claims. Some Medicare carriers will append it for you.
