About 0K9C00Z

0K9C00Z is the ICD-10-PCS code for a drainage procedure on the right hand muscle using an open approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to myotomy of hand, the ICD-9-CM procedure title it maps to (82.02).

For a different body part, codes include 0K9000Z (head muscle), 0K9100Z (facial muscle), 0K9200Z (right neck muscle), 0K9300Z (left neck muscle), 0K9400Z (tongue, palate, pharynx muscle), 0K9500Z (right shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0K9C30Z (percutaneous) and 0K9C40Z (percutaneous endoscopic).

With a different device, use 0K9C0ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 513 (Hand or Wrist Procedures, Except Major Thumb or Joint Procedures with CC/MCC), DRG 514 (Hand or Wrist Procedures, Except Major Thumb or Joint Procedures without CC/MCC), DRG 906 (Hand Procedures for Injuries), DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), DRG 958 (Other O.R. Procedures for Multiple Significant Trauma with CC) and DRG 959 (Other O.R. Procedures for Multiple Significant Trauma without CC/MCC), under the surgical categories “Hand or Wrist Procedures, Except Major Thumb or Joint Procedures”, “Hand Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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