Calcifcn and ossifictn of muscles assoc w burns, l shoulder

This diagnosis code signifies the abnormal hardening of muscle tissue in the left shoulder due to the deposition of calcium (calcification) and formation of bone (ossification), specifically as a sequela of a burn injury. This condition, known as myositis ossificans, restricts movement and can cause pain in the affected joint.

Use this code when documentation clearly indicates heterotopic ossification or calcification of the muscles in the left shoulder, and the etiology is directly linked to a previous burn injury. Supporting documentation should include a history of a burn affecting the left shoulder region and imaging reports (e.g., X-ray, CT scan) confirming the presence of calcification or ossification within the muscle tissue.

• Ensure the documentation specifies the left shoulder; laterality is crucial for accurate coding.
• Verify that the ossification/calcification is explicitly stated as being associated with burns, not other etiologies like trauma or genetic conditions.
• Sequence this code after the acute burn code (if still active) or a sequela of burn code, if applicable, to establish the causal link.
