About 0JNK0ZZ

0JNK0ZZ is the ICD-10-PCS code for a release procedure on the subcutaneous tissue and fascia, left hand 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 Fasciotomy of hand, the ICD-9-CM procedure title it maps to (82.12).

For a different body part, codes include 0JN00ZZ (subcutaneous tissue and fascia, scalp), 0JN10ZZ (subcutaneous tissue and fascia, face), 0JN40ZZ (subcutaneous tissue and fascia, right neck), 0JN50ZZ (subcutaneous tissue and fascia, left neck), 0JN60ZZ (subcutaneous tissue and fascia, chest), 0JN70ZZ (subcutaneous tissue and fascia, back) and 15 more.

The same procedure with a different approach is coded 0JNK3ZZ (percutaneous) and 0JNKXZZ (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 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.
