ICD-10 Code E09.43 – Drug or chemical induced diabetes mellitus with neurological complications with diabetic autonomic (poly)neuropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.43 – Drug or chemical induced diabetes mellitus with neurological complications with diabetic autonomic (poly)neuropathy
What it is
This code identifies diabetes caused by a drug or chemical exposure, with autonomic nerve involvement. Use it when the record links the diabetes to the substance and documents diabetic autonomic neuropathy.
Clinical signs
Clinical features vary; refer to documentation. Typical autonomic neuropathy findings may include abnormal heart rate, blood pressure changes, or gastrointestinal or bladder dysfunction, but the chart should confirm the neurologic complication.
When to use this code
Use E09.43 when the provider documents drug- or chemical-induced diabetes and specifically names diabetic autonomic neuropathy. It also fits when the diabetes is attributed to a medication or toxin and the autonomic complication is part of the assessment. Check documentation for the causal substance and complication wording.
Do not use for
Do not use this code for type 1, type 2, or gestational diabetes. Do not assign it if the record does not clearly connect the diabetes to a drug or chemical exposure, or if the neuropathy type is not documented.
Coding tip
Verify both elements in the note: the induced diabetes cause and the autonomic neuropathy complication.
