About 0K810ZZ

0K810ZZ is the ICD-10-PCS code for a division procedure on the facial muscle using an open approach. In ICD-10-PCS, division means cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part.

In plain terms, this corresponds to other division of soft tissue and other change in muscle or tendon length, the ICD-9-CM procedure titles it maps to (83.19 and 83.85).

For a different body part, codes include 0K800ZZ (head muscle), 0K820ZZ (right neck muscle), 0K830ZZ (left neck muscle), 0K840ZZ (tongue, palate, pharynx muscle), 0K850ZZ (right shoulder muscle), 0K860ZZ (left shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0K813ZZ (percutaneous) and 0K814ZZ (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 500 (Soft Tissue Procedures with MCC), DRG 501 (Soft Tissue Procedures with CC) and DRG 502 (Soft Tissue Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Soft Tissue Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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