ICD-10 Code E08.618 – Diabetes mellitus due to underlying condition with other diabetic arthropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E08.618 – Diabetes mellitus due to underlying condition with other diabetic arthropathy
What it is
This code identifies diabetes caused by an underlying condition, along with a diabetic joint disorder that does not fit a more specific arthropathy code. Use it when the record links both conditions clearly.
Clinical signs
Clinical features vary; refer to documentation. You may see joint pain, stiffness, swelling, or reduced range of motion in a patient with diabetes secondary to another disease.
When to use this code
Use E08.618 when the provider documents diabetes due to another underlying condition and also describes diabetic arthropathy, but not a more specific joint complication. Confirm that the underlying cause of diabetes is recorded in the chart.
This code supports cases where the arthropathy is attributed to diabetes rather than trauma, infection, or a separate rheumatologic disorder. Check documentation if the joint problem is described only nonspecifically.
Do not use for
Do not use this code if the diabetes is not due to an underlying condition or if the joint disorder is not documented as diabetic. Do not assign it for unrelated arthropathy.
Coding tip
Always code the underlying condition first when instructed by the classification, and verify that the provider links the diabetes and arthropathy.
