ICD-10 Code D86.87 – Sarcoid myositis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D86.87 – Sarcoid myositis
What it is
D86.87 identifies sarcoid myositis, a muscle manifestation of sarcoidosis. Use it when documentation states granulomatous muscle involvement rather than nonspecific muscle pain or weakness.
Clinical signs
Clinical features vary; refer to documentation. Reported findings may include proximal muscle weakness, muscle pain, swelling, or a palpable mass, with evidence of sarcoid granulomatous involvement on clinical or pathologic evaluation.
When to use this code
Use D86.87 when the provider documents sarcoid myositis, sarcoid muscle involvement, or muscular sarcoidosis. It fits cases where the diagnosis is established and the muscle condition is part of systemic sarcoidosis.
Do not use it for undifferentiated myalgia, generalized weakness, or other inflammatory myopathies unless sarcoidosis is specifically identified. Check documentation if the record does not clearly link the muscle findings to sarcoidosis.
Do not use for
Do not use for muscle symptoms without sarcoidosis, or for other myositis types such as infectious, drug-induced, or autoimmune myositis. Check documentation when the etiology is not stated.
Coding tip
Code D86.87 only when the record clearly connects the muscle disorder to sarcoidosis.
