What 11000 covers

This service involves actively removing extensive eczematous or infected skin, such as adherent crusted or diseased surface material, rather than simply cleansing or applying medication. Dermatologists, surgeons, and other clinicians performing skin procedures may provide it in an office, hospital, or other treatment setting. The indication and extent of the skin involvement distinguish this service from wound debridement selected by depth of tissue removed or treatment of a small benign callus.

Report 11000 for the initial area involving up to 10% of body surface; 11001 is an add-on for each additional 10%. Document the skin condition, the debridement performed, and the percentage of body surface treated so the initial and additional portions are supported. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and 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.

11000 billing questions

When is 11001 reported with 11000?

Use 11000 for the initial area involving up to 10% of body surface. Report 11001 for each additional 10% treated.

How does 11000 differ from wound debridement codes such as 11042?

11000 describes extensive debridement of eczematous or infected skin measured by percentage of body surface. Wound debridement codes such as 11042 are selected by the deepest tissue removed and the treated area.

What documentation supports reporting 11000?

Document the eczematous or infected skin condition, the debridement performed, and the percentage of body surface treated. The documented extent supports whether 11000 alone or an additional 11001 is appropriate.

Can modifier 50 be appended when both sides are treated?

No. The descriptor and anatomy make bilateral adjustment inappropriate for 11000.

Can same-day evaluation or postoperative care be billed separately?

The code has a 0-day global period, which includes same-day preoperative and postoperative care.

How does Medicare handle multiple procedures in the same session?

The highest-valued procedure is paid in full, and other procedures performed in that session are subject to the standard 50% multiple-procedure reduction.

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.
