Calcifcn and ossifictn of muscles assoc w burns, r low leg

This code describes heterotopic ossification, specifically the formation of bone within the muscle tissue of the right lower leg, occurring as a complication of a burn injury. This condition, also known as myositis ossificans traumatica, results in hardened, painful masses within the muscle, restricting movement and function.

Use this code when documentation clearly indicates the presence of calcification or ossification within the muscles of the patient's right lower leg, and a direct causal link to a previous burn injury is established. This diagnosis is typically confirmed by imaging studies such as X-rays or CT scans showing ectopic bone formation.

• Ensure the documentation specifies the right lower leg and explicitly links the ossification to a burn injury.
• Do not confuse with other forms of myositis ossificans not associated with burns, or with calcification of tendons or ligaments.
• Sequence this code after the acute burn code (if still active) or a late effect of burn code (T20-T25 with 7th character S) to establish the primary cause.
