About 07B50ZZ

07B50ZZ is the ICD-10-PCS code for a excision procedure on the lymphatic, right axillary using an open approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

The same procedure with a different approach is coded 07B53ZZ (percutaneous) and 07B54ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R.
