About 0KNC0ZZ

0KNC0ZZ is the ICD-10-PCS code for a release procedure on the right hand muscle using an open approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to lysis of adhesions of hand, the ICD-9-CM procedure title it maps to (82.91).

For a different body part, codes include 0KN00ZZ (head muscle), 0KN10ZZ (facial muscle), 0KN20ZZ (right neck muscle), 0KN30ZZ (left neck muscle), 0KN40ZZ (tongue, palate, pharynx muscle), 0KN50ZZ (right shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0KNC3ZZ (percutaneous), 0KNC4ZZ (percutaneous endoscopic) and 0KNCXZZ (external).

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 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC), DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC) and DRG 906 (Hand Procedures for Injuries), under the surgical categories “Hand or Wrist Procedures, Except Major Thumb or Joint Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures”, “Hand Procedures for Injuries” and 1 more.

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