When to Use

Use a code from this group when a surgical release is performed on the right upper arm muscle to relieve restriction or improve range of motion. These codes apply when the primary intent of the procedure is to free the muscle from abnormal physical constraints rather than to excise, repair, or replace tissue.

Typical Clinical Scenarios

A 68-year-old woman with a long-standing adhesive capsulitis and dense fibrotic contracture of the right proximal upper arm muscle presents with progressive loss of elbow flexion and significant functional impairment despite months of conservative therapy; she is admitted for planned surgical release under general anesthesia to cut adhesions and restore range of motion. Typical codes: 0KN70ZZ
A 45-year-old man involved in a motor vehicle collision arrives through the emergency department with an acute crush injury to the right upper arm causing compartmental scarring and tethering of muscle limiting neurovascular function; after stabilization, an urgent percutaneous release is performed at bedside or in the OR to free the muscle from constricting scar tissue. Typical codes: 0KN73ZZ
A 52-year-old patient with recurrent post-traumatic flexion contracture of the right upper arm previously treated with open surgery now undergoes a minimally invasive endoscopic procedure to release recurrent adhesions and improve function while minimizing repeat open dissection. Typical codes: 0KN74ZZ, 0KN70ZZ
