ICD-10 Code D86.1 – Sarcoidosis of lymph nodes (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D86.1 – Sarcoidosis of lymph nodes
What it is
D86.1 identifies sarcoidosis involving lymph nodes. It means granulomatous inflammation is present in lymphatic tissue, often as part of a systemic sarcoidosis diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Common findings include enlarged lymph nodes, especially in the chest, and evidence of noncaseating granulomas on evaluation.
When to use this code
Use D86.1 when the provider documents sarcoidosis affecting lymph nodes, whether the diagnosis is confirmed by imaging, biopsy, or specialist assessment. It may be used when lymph node involvement is the stated manifestation of known sarcoidosis. If the record only says lymphadenopathy without sarcoidosis, do not assign this code.
Do not use for
Do not use this code for unspecified sarcoidosis or for lymph node enlargement from infection, malignancy, or other causes. Check documentation if the record does not clearly link the nodes to sarcoidosis.
Coding tip
Code the documented site and confirm that sarcoidosis, not just adenopathy, is explicitly stated.
