ICD-10 Code D86.0 – Sarcoidosis of lung (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D86.0 – Sarcoidosis of lung
What it is
D86.0 identifies sarcoidosis involving the lung. It is a granulomatous inflammatory disease that affects pulmonary tissue and may be part of a broader systemic condition.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include cough, shortness of breath, chest imaging abnormalities, and evidence of pulmonary granulomatous disease.
When to use this code
Use D86.0 when the provider documents sarcoidosis of the lung or pulmonary sarcoidosis. Apply it when the lung is the stated site of involvement, even if the disease is also systemic. If the record only says sarcoidosis without a lung site, check documentation.
Do not use for
Do not use this code for sarcoidosis limited to another organ or for a nonspecific sarcoidosis diagnosis without pulmonary involvement. If the chart does not clearly identify the lung, verify the site before coding.
Coding tip
Look for explicit documentation of pulmonary involvement and code the condition exactly as stated by the provider.
