ICD-10 Code D86.86 – Sarcoid arthropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D86.86 – Sarcoid arthropathy
What it is
D86.86 identifies joint involvement caused by sarcoidosis. Use it when the record documents sarcoid-related arthritis or arthropathy affecting one or more joints.
Clinical signs
Clinical features vary; refer to documentation. Notes may describe joint pain, swelling, stiffness, or inflammatory arthritis in the setting of known sarcoidosis.
When to use this code
Use D86.86 when the clinician specifically links the arthropathy to sarcoidosis. It is appropriate for encounters documenting sarcoid arthritis, sarcoid polyarthritis, or other sarcoid joint disease. If the chart only says “arthralgia” without that link, check documentation.
Do not use for
Do not use this code for nonspecific joint pain, osteoarthritis, or arthritis from another cause. If sarcoidosis is present but joint involvement is not documented, do not assume D86.86.
Coding tip
Confirm the provider’s wording ties the joint disorder to sarcoidosis before assigning D86.86.
