About 0KN10ZZ
0KN10ZZ is the ICD-10-PCS code for a release procedure on the facial muscle 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 0KN00ZZ (head muscle), 0KN20ZZ (right neck muscle), 0KN30ZZ (left neck muscle), 0KN40ZZ (tongue, palate, pharynx muscle), 0KN50ZZ (right shoulder muscle), 0KN60ZZ (left shoulder muscle) and 21 more.
The same procedure with a different approach is coded 0KN13ZZ (percutaneous), 0KN14ZZ (percutaneous endoscopic) and 0KN1XZZ (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.
