CPT for ENT: Modifier- 59 Scrutinized
Modifier -59 Distinct Procedural Service is described by the American Medical Associations CPT 2004 Professional Edition as, For procedure(s)/services(s) not ordinarily performed or encountered on the same day by the same physician, but appropriate under certain circumstances (eg, different site or organ system, separate excision or lesion.) Plainly stated, modifier -59 is used to bill procedures performed on the same date of service that represent a:
- different session or patient encounter
- different procedure or surgery
- different site or organ system
- separate incision/excision or lesion
- separate injury (or area of surgery in extensive injuries)
Physicians should only use -59 modifier when there is no other modifier more appropriate. You may only append modifier -59 to the lesser service(s). There has been some controversy over proper use of the -59 modifier and otolaryngology offices have had trouble determining when it is appropriate to use the -59 modifier. Adding to this trouble is recent monitoring of the use of this modifier by private insurance carriers and the Centers for Medicare and Medicaid Services (CMS). In 2004, the OIG is joining other carriers in scrutinizing modifier -59 claims.
All all have reported increased use of modifier -59 by physician offices, usually to override bundling edits and Medicares Correct Coding Initiative. Make sure that when filing claims with the -59 modifier, your documentation supports its usage as a separate and distinct procedure. Remember, modifier -59 is not intended to report procedures that took extra time or were performed to faciliatate or provide access to a primary procedure that was done. If you've met all of the above requirements, modifier -59 can be used to differentiate services.

CPT for ENT articles are a collaborative effort between the Academy’s team of CPT Advisors, members of the Physician Payment Policy (3P) workgroup, and health policy staff. Articles are developed to address common coding questions received by the health policy team, as well as to clarify coding changes and correct coding principles for frequently reported ENT procedures. These articles are not intended as legal, medical, or business advice and are not a guarantee of reimbursement. The information is also not meant to serve as the definitive or sole authority on billing and coding issues. The applicability of AAO-HNS billing and coding guidance for a particular procedure, must be determined by the responsible physician in light of all the circumstances presented by the individual patient. You should consult with your own advisors as well as Medicare or private carriers in making any decisions about how to bill and code particular services or procedures.
