075M0ZZDestruction of Thymus, Open Approach

075M0ZZ is the ICD-10-PCS code for a destruction procedure on the thymus using an open approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

In plain terms, this corresponds to other partial excision of thymus, the ICD-9-CM procedure title it maps to (07.81).

For a different body part, codes include 07500ZZ (lymphatic, head), 07510ZZ (lymphatic, right neck), 07520ZZ (lymphatic, left neck), 07530ZZ (lymphatic, right upper extremity), 07540ZZ (lymphatic, left upper extremity), 07550ZZ (lymphatic, right axillary) and 14 more.

The same procedure with a different approach is coded 075M3ZZ (percutaneous) and 075M4ZZ (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.
