About 0JN40ZZ

0JN40ZZ is the ICD-10-PCS code for a release procedure on the subcutaneous tissue and fascia, right neck 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 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 0JN00ZZ (subcutaneous tissue and fascia, scalp), 0JN10ZZ (subcutaneous tissue and fascia, face), 0JN50ZZ (subcutaneous tissue and fascia, left neck), 0JN60ZZ (subcutaneous tissue and fascia, chest), 0JN70ZZ (subcutaneous tissue and fascia, back), 0JN80ZZ (subcutaneous tissue and fascia, abdomen) and 15 more.

The same procedure with a different approach is coded 0JN43ZZ (percutaneous) and 0JN4XZZ (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.
