07TM0ZZResection of Thymus, Open Approach

07TM0ZZ is the ICD-10-PCS code for a resection procedure on the thymus using an open approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to other total excision of thymus, the ICD-9-CM procedure title it maps to (07.82).

For a different body part, codes include 07T00ZZ (lymphatic, head), 07T10ZZ (lymphatic, right neck), 07T20ZZ (lymphatic, left neck), 07T30ZZ (lymphatic, right upper extremity), 07T40ZZ (lymphatic, left upper extremity), 07T50ZZ (lymphatic, right axillary) and 14 more.

The same procedure with a different approach is coded 07TM4ZZ (percutaneous endoscopic).

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.
