Separation of muscle (nontraumatic), unspecified shoulder

This code signifies a spontaneous, non-injury-related separation or detachment of muscle fibers within the shoulder region. It describes a condition where the muscle tissue has pulled apart without an external traumatic event, such as a fall or direct impact. The specific muscle involved in the shoulder is not documented or is unknown.

Use this code when documentation clearly states a "nontraumatic muscle separation" or "spontaneous muscle tear" in the shoulder, and no further specificity regarding the affected muscle or laterality is provided. This code is appropriate when the physician explicitly rules out trauma as the cause of the muscle separation.

• Ensure documentation explicitly states "nontraumatic" or "spontaneous" to differentiate from traumatic muscle injuries.
• Avoid using this code if the specific shoulder muscle (e.g., deltoid, rotator cuff) is identified; instead, use a more specific code from the M62.0- series.
• If laterality (right or left shoulder) is documented, select the appropriate laterality-specific code (M62.011 or M62.012).
