ICD-10 Code D86.9 – Sarcoidosis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D86.9 – Sarcoidosis, unspecified
What it is
D86.9 identifies sarcoidosis when the record does not specify the affected organ or site. It is a systemic inflammatory condition marked by granuloma formation, but the documentation is nonspecific.
Clinical signs
Clinical features vary; refer to documentation. Sarcoidosis may present with cough, dyspnea, fatigue, skin lesions, eye findings, or incidental imaging abnormalities, but the site and severity must be documented.
When to use this code
Use D86.9 when the provider diagnoses sarcoidosis and does not document a specific organ involvement such as lung, skin, or lymph nodes. It also fits when the chart confirms sarcoidosis but the available note is too general for a more specific code.
Do not use for
Do not use this code if the record identifies a specific sarcoidosis site or manifestation; choose the more precise code instead. Do not use it for suspected sarcoidosis without a confirmed diagnosis.
Coding tip
If the note says only “sarcoidosis,” code D86.9 unless another documented site supports a more specific code.
