About 0PNM0ZZ

0PNM0ZZ is the ICD-10-PCS code for a release procedure on the right carpal 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 other repair or plastic operations on bone, carpals and metacarpals, the ICD-9-CM procedure title it maps to (78.44).

For a different body part, codes include 0PN00ZZ (sternum), 0PN10ZZ (ribs, 1 to 2), 0PN20ZZ (ribs, 3 or more), 0PN30ZZ (cervical vertebra), 0PN40ZZ (thoracic vertebra), 0PN50ZZ (right scapula) and 20 more.

The same procedure with a different approach is coded 0PNM3ZZ (percutaneous) and 0PNM4ZZ (percutaneous endoscopic).

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.
