07TM4ZZResection of Thymus, Percutaneous Endoscopic Approach

07TM4ZZ is the ICD-10-PCS code for a resection procedure on the thymus 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 thoracoscopic total excision of thymus, the ICD-9-CM procedure title it maps to (07.84).

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 07TM0ZZ (open).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC) and DRG 165 (Major Chest Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Major Chest Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures” and 5 more.

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