About 0LN64ZZ

0LN64ZZ is the ICD-10-PCS code for a release procedure on the left lower arm and wrist tendon 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 0LN04ZZ (head and neck tendon), 0LN14ZZ (right shoulder tendon), 0LN24ZZ (left shoulder tendon), 0LN34ZZ (right upper arm tendon), 0LN44ZZ (left upper arm tendon), 0LN54ZZ (right lower arm and wrist tendon) and 21 more.

The same procedure with a different approach is coded 0LN60ZZ (open), 0LN63ZZ (percutaneous) and 0LN6XZZ (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.
