Other rupture of muscle (nontraumatic), unspecified shoulder

This code signifies a spontaneous, non-traumatic tear or disruption of a muscle in the shoulder region. It indicates that the specific muscle involved is not identified in the clinical documentation. This condition typically presents with sudden pain, weakness, and impaired range of motion in the affected shoulder.

Use this code when documentation clearly states a non-traumatic muscle rupture of the shoulder, but the specific muscle (e.g., biceps, deltoid) is not specified. This code is appropriate for spontaneous ruptures, such as those due to degenerative changes or overuse, without an acute external injury. Documentation should explicitly rule out a traumatic etiology.

• Avoid using this code if a specific muscle is identified; instead, use a more precise code from the M62.1- series.
• Ensure documentation explicitly states "nontraumatic" or "spontaneous" to support this code.
• If the rupture is due to an acute injury, a traumatic muscle rupture code (e.g., S46.-) should be used instead.
