About 0KJX4ZZ

0KJX4ZZ is the ICD-10-PCS code for a inspection procedure on the upper muscle using a percutaneous endoscopic approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to other diagnostic procedures on muscle, tendon, fascia, and bursa, including that of hand, the ICD-9-CM procedure title it maps to (83.29).

For a different body part, codes include 0KJY4ZZ (lower muscle).

The same procedure with a different approach is coded 0KJX0ZZ (open), 0KJX3ZZ (percutaneous) and 0KJXXZZ (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.
