Paralytic calcifcn and ossification of muscle, right ank/ft

This code signifies the presence of abnormal calcium deposits and bone formation within the muscle tissue of the right ankle and foot, specifically when these changes are associated with paralysis. This condition, known as myositis ossificans, leads to hardening and restricted movement due to the ossified muscle.

Use this code when documentation clearly indicates paralytic myositis ossificans affecting the muscles of the right ankle and foot. This typically occurs in patients with a history of neurological injury or disease leading to paralysis, where muscle immobility contributes to the ectopic bone formation. Supporting documentation would include imaging reports (X-ray, CT scan) confirming ossification and clinical notes detailing the associated paralysis.

• Ensure the documentation specifies "paralytic" involvement; otherwise, consider non-paralytic myositis ossificans codes.
• Verify the laterality (right ankle and foot) is explicitly stated in the medical record.
• Code any underlying paralytic condition (e.g., stroke sequelae, spinal cord injury) as a primary diagnosis if it is the reason for the encounter, with this code as a secondary diagnosis.
