What 11046 covers

This add-on represents debridement of additional wound area when the clinician removes nonviable tissue through muscle or fascia. It commonly accompanies wound care for pressure injuries, diabetic foot ulcers, or traumatic wounds, in a wound clinic, office, or operating room. The code selection follows the deepest tissue actually removed, not simply the wound’s appearance or diagnosis.

Report 11046 with 11043, the primary code for the initial area at this tissue depth. Each unit covers another 20 square centimeters or part of that increment beyond the first 20; document the total area debrided at muscle or fascia depth and the tissue removed. When multiple wounds are treated at the same depth, their areas are combined for code selection; do not combine areas debrided to different depths. As an add-on, 11046 is billed only with a primary procedure and paid within that 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.

11046 billing questions

Which primary code must accompany 11046?

Report 11046 with 11043, which represents the initial area debrided at muscle or fascia depth. It is not a stand-alone code.

How many units should be reported?

Count each additional 20 square centimeters or part of that increment beyond the initial 20 square centimeters. For example, a total treated area of 41 square centimeters at this depth supports two units of 11046 with 11043.

How is the area determined when there are multiple wounds?

Combine the surface areas of wounds debrided to the same depth. Keep areas debrided to different tissue depths separate.

What documentation supports 11046?

Record the tissue actually removed, the depth reached, and the total surface area debrided at muscle or fascia depth. The note should support the additional area beyond the initial 20 square centimeters.

Does 11046 have its own global period?

CMS identifies it as an add-on paid within the primary procedure’s global period. It must be reported with the primary procedure.

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.
