About 0KC40ZZ

0KC40ZZ is the ICD-10-PCS code for a extirpation procedure on the tongue, palate, pharynx muscle using an open approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to myotomy, the ICD-9-CM procedure title it maps to (83.02).

For a different body part, codes include 0KC00ZZ (head muscle), 0KC10ZZ (facial muscle), 0KC20ZZ (right neck muscle), 0KC30ZZ (left neck muscle), 0KC50ZZ (right shoulder muscle), 0KC60ZZ (left shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0KC43ZZ (percutaneous) and 0KC44ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 500 (Soft Tissue Procedures with MCC), DRG 501 (Soft Tissue Procedures with CC), DRG 502 (Soft Tissue 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 “Soft Tissue Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Other O.R. Procedures for Injuries”.

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