What 97598 covers
97598 represents additional selective removal of devitalized tissue and wound debris from open wounds, beyond the area covered by the primary service. The clinician works to remove nonviable tissue while preserving viable tissue; the service may involve sharp instruments or other selective methods. Physicians and wound-care clinicians, including physical or occupational therapists, may perform it in settings such as an outpatient wound clinic, hospital outpatient department, or office.
Report 97598 only with its primary code, 97597. Count the additional area debrided in increments of 20 cm² or less; the final increment may be a fraction of 20 cm². Documentation should identify the wound area actually treated, the selective debridement performed, and the tissue removed. CMS classifies 97598 as an add-on code and pays it within the primary procedure's global period.
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.

97598 billing questions
Can 97598 be reported by itself?
No. It is an add-on code and must be reported with the primary selective debridement service, 97597.
How many units should be reported?
Report one unit for each additional 20 cm² or portion thereof debrided after the area covered by 97597. Base units on the area actually treated, not simply the wound's overall dimensions.
What documentation supports 97598?
Document the wound or wounds treated, the area selectively debrided, and the procedure and tissue removed. The record should support the additional area beyond the primary service.
When should 11042 be considered instead?
Use 11042 when the service is excisional debridement extending into subcutaneous tissue. 97598 describes additional selective debridement and is reported with 97597.
How does the global-period rule affect payment?
CMS treats 97598 as an add-on paid within the global period of its primary procedure. It is not a standalone primary service.
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.
