What 11001 covers
This add-on represents debridement of extensive eczematous or infected skin beyond the area captured by the primary service. A dermatologist or another physician managing widespread skin disease may perform the service in an office, hospital, or other treatment setting. The relevant measure is the percentage of total body surface area debrided, not the wound’s depth or its area in square centimeters.
Report 11001 only with 11000, which accounts for the initial body-surface portion; use one unit for each additional 10% or part of 10%. Documentation should identify the condition treated, the skin debrided, and the percentage of body surface area involved so the additional units are supported. CMS classifies 11001 as an add-on code, with payment handled 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.

11001 billing questions
Can 11001 be reported by itself?
No. It is an add-on to 11000 and represents body-surface area beyond the portion captured by that primary code.
How many units should be reported?
Report one unit for each additional 10% of body surface area, or part of 10%, debrided beyond the area represented by 11000.
What documentation supports the additional units?
Document the eczematous or infected skin treated and the percentage of total body surface area debrided, including the additional area beyond the primary portion.
Should 11001 be used for a deep wound debridement?
Not based on wound depth. Codes such as 11042–11044 describe wound debridement by the deepest tissue removed and use square-centimeter measurements; 11001 measures additional body-surface area for extensive eczematous or infected skin.
How does the global period affect 11001?
CMS treats this add-on within the global period of its primary procedure. Report it with 11000 rather than as a separate 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.
