Other ossification of muscle, left shoulder

This code signifies the abnormal formation of bone tissue within the muscle of the left shoulder, excluding myositis ossificans traumatica. This condition, often referred to as heterotopic ossification, results in the hardening and stiffening of muscle tissue due to bone growth where it shouldn't be.

Apply this code when documentation specifies non-traumatic ossification within the muscles of the left shoulder. This includes idiopathic cases or those secondary to neurological injury, burns, or surgical procedures, provided the ossification is not directly attributed to a specific traumatic event.

• Differentiate from myositis ossificans traumatica (M61.0-), which is specifically post-traumatic.
• Ensure laterality is clearly documented as "left shoulder" to support this specific code.
• Consider an additional code for the underlying cause if known and relevant (e.g., neurological condition, burn sequela).
