About 0K9D0ZZ

0K9D0ZZ is the ICD-10-PCS code for a drainage procedure on the left hand muscle using an open approach. 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 0K900ZZ (head muscle), 0K910ZZ (facial muscle), 0K920ZZ (right neck muscle), 0K930ZZ (left neck muscle), 0K940ZZ (tongue, palate, pharynx muscle), 0K950ZZ (right shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0K9D3ZZ (percutaneous) and 0K9D4ZZ (percutaneous endoscopic).

With a different device, use 0K9D00Z (drainage 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.
