About 0MNF4ZZ

0MNF4ZZ is the ICD-10-PCS code for a release procedure on the sternum 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 lysis of adhesions of muscle, tendon, fascia, and bursa, the ICD-9-CM procedure title it maps to (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 0MNF0ZZ (open), 0MNF3ZZ (percutaneous) and 0MNFXZZ (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.
