ICD-10 Code E09.610 – Drug or chemical induced diabetes mellitus with diabetic neuropathic arthropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.610 – Drug or chemical induced diabetes mellitus with diabetic neuropathic arthropathy
What it is
This code identifies diabetes caused by a drug or chemical, complicated by neuropathic arthropathy, also called Charcot joint. Use it when the record links the diabetes and joint damage to the same external cause.
Clinical signs
Findings usually include neuropathy with progressive joint destruction, deformity, swelling, warmth, or instability, most often in the foot or ankle. Clinical features vary; refer to documentation.
When to use this code
Use E09.610 when the provider documents drug- or chemical-induced diabetes and specifically states diabetic neuropathic arthropathy. The chart should connect the arthropathy to the diabetes, not just note neuropathy alone. If the cause or complication is unclear, check documentation.
Do not use for
Do not use this code for type 1, type 2, or gestational diabetes. It also is not appropriate for neuropathy without arthropathy, or for arthropathy unrelated to diabetic neuropathic changes.
Coding tip
Verify both the diabetes cause and the joint complication in the provider note before assigning E09.610.
