About 0MNP4ZZ

0MNP4ZZ is the ICD-10-PCS code for a release procedure on the left knee bursa and ligament using a percutaneous endoscopic 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 division of joint capsule, ligament, or cartilage, knee and lysis of adhesions of muscle, tendon, fascia, and bursa, the ICD-9-CM procedure titles it maps to (80.46 and 83.91).

For a different body part, codes include 0MN04ZZ (head and neck bursa and ligament), 0MN14ZZ (right shoulder bursa and ligament), 0MN24ZZ (left shoulder bursa and ligament), 0MN34ZZ (right elbow bursa and ligament), 0MN44ZZ (left elbow bursa and ligament), 0MN54ZZ (right wrist bursa and ligament) and 21 more.

The same procedure with a different approach is coded 0MNP0ZZ (open), 0MNP3ZZ (percutaneous) and 0MNPXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 500 (Soft Tissue Procedures with MCC), DRG 501 (Soft Tissue Procedures with CC) and DRG 502 (Soft Tissue Procedures without CC/MCC), under the surgical category “Soft Tissue Procedures”.

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