Other ossification of muscle, right forearm

This code signifies the abnormal formation of bone within the muscle tissue of the patient's right forearm, excluding myositis ossificans traumatica. This heterotopic ossification can lead to pain, swelling, and restricted range of motion in the affected limb.

Apply this code when documentation specifies ossification within the muscle of the right forearm, without a clear traumatic etiology. This is appropriate for conditions like progressive osseous heteroplasia affecting the forearm. Physician notes should clearly indicate the location and nature of the ossification.

• Differentiate from myositis ossificans traumatica (M61.0-), which has a specific traumatic origin.
• Ensure laterality is clearly documented as "right forearm" to support this specific code.
• Consider additional codes for any associated symptoms or underlying conditions contributing to the ossification.
