Sarcoid myositis
ICD10CM code
Sarcoid Myositis (ICD-10 D86.87)
Name of the Condition
- Common Name(s): Sarcoid Myositis
- Medical Term: Myositis (Muscle inflammation) associated with Sarcoidosis.
Summary
Sarcoid Myositis is a rare form of sarcoidosis where inflammatory cells collect in the muscle tissue, leading to muscle weakness and discomfort. Sarcoidosis itself is a systemic inflammatory disease that primarily affects the lungs and lymph glands.
Causes
The exact cause of sarcoid myositis is unknown, but it is thought to be linked to an abnormal immune response. It is associated with the broader condition of sarcoidosis, which may be triggered by environmental exposures, infections, or genetic factors.
Risk Factors
- Age: Typically affects individuals between 20 and 40 years old.
- Ethnicity: Higher prevalence in African-American and Scandinavian populations.
- Family History: Presence of sarcoidosis in family members may increase risk.
- Gender: Slightly more prevalent in females.
Symptoms
- Muscle weakness, especially in the upper arms and legs.
- Muscle pain or discomfort.
- Decreased physical endurance.
- Possible fatigue and joint pain due to systemic involvement.
Diagnosis
- Blood Tests: Elevated serum angiotensin-converting enzyme (ACE) levels.
- MRI or CT Scan: Imaging to assess muscle inflammation.
- Muscle Biopsy: Confirmation through tissue sample revealing granulomas.
- Electromyography (EMG): Evaluates electrical activity in muscles.
Treatment Options
- Corticosteroids: To reduce inflammation and improve muscle strength.
- Immunosuppressive Drugs: Used when corticosteroids are insufficient or cause side effects.
- Physical Therapy: Helps improve muscle function and reduce stiffness.
Prognosis and Follow-Up
The prognosis varies; some experience significant improvement with treatment, while others may have persistent muscle weakness. Regular follow-up is crucial to monitor therapy response and adjust treatment plans.
Complications
- Chronic muscle weakness leading to reduced mobility.
- Possible development of sarcoidosis-related complications in other organs, such as lungs or heart.
Lifestyle & Prevention
- Exercise: Regular, gentle exercise to maintain muscle strength and flexibility.
- Diet: Nutritious diet to support immune and overall health.
- Avoidance of Smoking: To reduce further immune system stress.
When to Seek Professional Help
Seek medical attention if you experience persistent or worsening muscle weakness, unusual muscle pain, or if you have a known history of sarcoidosis and develop new symptoms.

Tips for Medical Coders
- Ensure accurate linkage between sarcoidosis and muscle involvement when coding.
- Avoid misclassifying as mere muscular dystrophy since sarcoid myositis involves systemic inflammatory pathology.
