About 0KB40ZZ

0KB40ZZ is the ICD-10-PCS code for a excision procedure on the tongue, palate, pharynx muscle using an open approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to excision of lesion of muscle and other myectomy, the ICD-9-CM procedure titles it maps to (83.32 and 83.45).

For a different body part, codes include 0KB00ZZ (head muscle), 0KB10ZZ (facial muscle), 0KB20ZZ (right neck muscle), 0KB30ZZ (left neck muscle), 0KB50ZZ (right shoulder muscle), 0KB60ZZ (left shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0KB43ZZ (percutaneous) and 0KB44ZZ (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 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC) and DRG 500 (Soft Tissue Procedures with MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Circulatory System O.R. Procedures”, “Soft Tissue Procedures” and 3 more.

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