ICD-10-PCS Code For Left Shoulder Muscle: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0KN6 includes procedures performed to release muscular structures in the left shoulder. These ICD-10-PCS codes are used for inpatient documentation when a left shoulder muscle requires surgical release to free it from abnormal physical constraints such as adhesions, contractures, or entrapment. Accurate coding within the ICD-10-PCS 0KN6 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Shoulder Muscle, Left Release Procedure Overview

This procedure group includes release operations performed on the left shoulder muscle and targets the Muscles body system. These procedures involve freeing the shoulder muscle from abnormal physical constraints by cutting or applying force to restore range of motion or relieve entrapment. Accurate ICD-10-PCS coding of these releases is important for inpatient reimbursement and for reflecting the clinical intervention performed.

Typical Clinical Scenarios

An elderly patient with a chronic adhesive capsulitis and prolonged loss of passive and active range of motion in the left shoulder despite extensive physical therapy is admitted for an elective surgical procedure to restore function; the surgeon performs a targeted release of scarred muscular adhesions in the left shoulder under general anesthesia to free the muscle and improve motion. Typical codes: 0KN60ZZ, 0KN64ZZ
A middle-aged laborer presents to the ED after an acute left shoulder hyperextension injury with an associated muscle entrapment and persistent neurovascular compromise; after failed closed management and progressive functional deficit, the team proceeds to an urgent operative release of the entrapped left shoulder muscle to relieve constriction and prevent further ischemic or neurologic injury. Typical codes: 0KN60ZZ, 0KN63ZZ
A patient with prior left shoulder surgery develops post-surgical contracture of the shoulder musculature causing pain and limited mobility; during a planned inpatient revision procedure the surgeon uses an external approach to release dense perimuscular scar tissue and restore shoulder mechanics. Typical codes: 0KN6XZZ
