About 07B93ZZ

07B93ZZ is the ICD-10-PCS code for a excision procedure on the left lymphatic, internal mammary using a percutaneous approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to excision of internal mammary lymph node, the ICD-9-CM procedure title it maps to (40.22).

For a different body part, codes include 07B03ZZ (lymphatic, head), 07B13ZZ (lymphatic, right neck), 07B23ZZ (lymphatic, left neck), 07B33ZZ (lymphatic, right upper extremity), 07B43ZZ (lymphatic, left upper extremity), 07B53ZZ (lymphatic, right axillary) and 14 more.

The same procedure with a different approach is coded 07B90ZZ (open) and 07B94ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest Procedures without CC/MCC), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Major Chest Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Other O.R. Procedures of the Blood and Blood Forming Organs”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
