About 0MNKXZZ

0MNKXZZ is the ICD-10-PCS code for a release procedure on the perineum bursa and ligament using an external 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 0MN0XZZ (head and neck bursa and ligament), 0MN1XZZ (right shoulder bursa and ligament), 0MN2XZZ (left shoulder bursa and ligament), 0MN3XZZ (right elbow bursa and ligament), 0MN4XZZ (left elbow bursa and ligament), 0MN5XZZ (right wrist bursa and ligament) and 21 more.

The same procedure with a different approach is coded 0MNK0ZZ (open), 0MNK3ZZ (percutaneous) and 0MNK4ZZ (percutaneous endoscopic).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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