Other calcification of muscle, left thigh

This diagnosis code signifies the presence of abnormal calcium deposits within the muscle tissue of the patient's left thigh, excluding myositis ossificans traumatica. These calcifications are typically non-traumatic in origin and can lead to pain, stiffness, or restricted movement in the affected limb.

Use this code when documentation clearly indicates calcification of the muscle in the left thigh, and the etiology is not attributed to trauma. This code is appropriate for conditions such as tumoral calcinosis, metastatic calcification, or dystrophic calcification not otherwise specified as traumatic. Supporting documentation should include imaging reports (e.g., X-ray, CT scan) confirming the calcification and a physician's note specifying the location and non-traumatic nature.

• Ensure the documentation specifies "left thigh" to avoid laterality errors.
• Differentiate from myositis ossificans traumatica (M61.0- series) which has a distinct traumatic etiology.
• Review for any underlying systemic conditions that might be causing the calcification, as these may require additional coding.
