Paralytic calcification and ossification of muscle, unspecified lower leg
ICD10CM code
Name of the Condition
- Paralytic Calcification and Ossification of Muscle, Unspecified Lower Leg
- Commonly referred to as heterotopic ossification or myositis ossificans in the context of muscle paralysis
Summary
Paralytic calcification and ossification of muscle in the lower leg is a condition where abnormal bone formation occurs in muscles, often following muscle paralysis. The muscles and soft tissues become calcified, which can lead to discomfort and mobility issues.
Causes
The precise cause is not always clear, but it is commonly associated with:
- Trauma or injury to the muscle
- Neurological conditions that lead to muscle paralysis
- Post-surgical complications
Risk Factors
- History of muscle injury or trauma
- Neuromuscular disorders, including stroke or spinal cord injuries
- Genetic predisposition to abnormal bone growth
Symptoms
- Pain and swelling in the affected area
- Stiffness and reduced range of motion
- Palpable hard mass in the muscle
Diagnosis
- Physical examination to assess the symptoms
- Imaging techniques such as X-rays, CT scans, or MRI to visualize calcification or ossification
- Biopsies if necessary to rule out other conditions
Treatment Options
- Physical therapy to maintain mobility and reduce stiffness
- Nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve pain
- Surgical removal of ossified tissue in severe cases
- Radiation therapy in certain circumstances to inhibit bone growth
Prognosis and Follow-Up
- Prognosis varies; early intervention can lead to better outcomes
- Regular monitoring to prevent or manage recurrences
- Long-term rehabilitation to maintain muscle function and flexibility
Complications
- Permanent joint stiffness or immobility
- Chronic pain
- Potential for nerve damage if the ossification compresses nerve structures
Lifestyle & Prevention
- Regular physical activity to maintain muscle function
- Protective measures to prevent muscle injury
- Early treatment of potential contributory conditions like paralysis
When to Seek Professional Help
- Increasing pain or swelling in the lower leg
- Noticeable decrease in mobility or stiffness in the leg
- Development of a hard mass in the muscle

Tips for Medical Coders
- Ensure accuracy by correlating clinical documentation with imaging reports confirming ossification
- Be cautious of differentiating between traumatic and non-traumatic ossification in coding
- Verify the unspecified lower leg specification to avoid incorrect coding of anatomical sites
