About 07T94ZZ
07T94ZZ is the ICD-10-PCS code for a resection procedure on the left lymphatic, internal mammary using a percutaneous endoscopic approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.
In plain terms, this corresponds to radical excision of other lymph nodes, the ICD-9-CM procedure title it maps to (40.59).
For a different body part, codes include 07T04ZZ (lymphatic, head), 07T14ZZ (lymphatic, right neck), 07T24ZZ (lymphatic, left neck), 07T34ZZ (lymphatic, right upper extremity), 07T44ZZ (lymphatic, left upper extremity), 07T54ZZ (lymphatic, right axillary) and 14 more.
The same procedure with a different approach is coded 07T90ZZ (open).
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. Procedures with CC) and DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Respiratory System O.R. Procedures”, “Other Digestive System O.R. Procedures” and 9 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
