What 17004 covers

This service covers destroying 15 or more premalignant skin lesions in one session. A typical case involves numerous actinic keratoses on the face, scalp, ears, forearms, or hands. Dermatologists, primary care physicians, and advanced practice clinicians perform it, most often in the office. Liquid nitrogen cryosurgery is the usual method. Curettement, electrosurgery, chemical destruction, and laser are also methods of destruction. Count the premalignant lesions treated during the session, regardless of their locations.

When 15 or more lesions are treated, report one unit of 17004, not 17000 or 17003. For fewer lesions, report 17000 for the first and one unit of 17003 for each additional lesion through the fourteenth. Documentation should state the count, anatomic locations, diagnosis, and destruction method. The procedure has a 10-day global period, which includes related postoperative visits during those 10 days. Modifier 50 is inappropriate even when lesions are treated on both sides of the body. CMS does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

17004 billing questions

How many units of 17004 are reported if 30 actinic keratoses are destroyed?

One unit. This code covers 15 or more lesions in a single session regardless of how many above that threshold are treated.

Can 17000 and 17003 be reported along with 17004?

No. At 15 or more premalignant lesions in a session, 17004 replaces the 17000 and 17003 combination. Reporting them together would duplicate the lesion destruction.

Can an E/M visit be billed on the same day?

Yes, if the E/M service is significant and separately identifiable from the usual assessment for this minor procedure, such as evaluation of an unrelated problem. Append modifier 25 to the E/M code; the routine decision to destroy the lesions is included in the procedure.

Is a biopsy of a different lesion separately reportable?

Yes, when a separate suspicious lesion is biopsied rather than destroyed. Report the appropriate biopsy code, such as 11102 for a tangential biopsy; use modifier 59 or XS when an edit requires a distinct-service modifier, and document both lesions.

Should the treated lesions be listed by location?

Yes. Record the total count and anatomic sites, such as the face, scalp, and dorsal hands, so the 15-lesion threshold can be verified.

What if photodynamic therapy is used instead of conventional destruction?

For physician- or qualified-health-care-professional-performed photodynamic therapy with application and activation of a photosensitizing drug, report 96573 instead. Report 96574 when that service also includes debridement of hyperkeratotic premalignant lesions.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
