ICD-10 Code E09.44 – Drug or chemical induced diabetes mellitus with neurological complications with diabetic amyotrophy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.44 – Drug or chemical induced diabetes mellitus with neurological complications with diabetic amyotrophy
What it is
This code identifies diabetes caused by a drug or chemical, with a neurologic complication specifically documented as diabetic amyotrophy. Use it when the record links the diabetes and the neuropathic syndrome.
Clinical signs
Clinical features vary; refer to documentation. Diabetic amyotrophy is typically described as painful weakness and wasting of the proximal lower limb muscles, often with weight loss and asymmetric onset.
When to use this code
Use E09.44 when the provider documents drug- or chemical-induced diabetes mellitus and names diabetic amyotrophy as the neurologic complication. It may appear in notes describing neuropathic leg pain, proximal weakness, or muscle atrophy tied to the diabetes cause. Check documentation if the causal agent or complication is unclear.
Do not use for
Do not use this code for diabetes without a documented drug or chemical cause, or for diabetic neuropathy that is not specified as amyotrophy. Check documentation when the neurologic complication is described differently.
Coding tip
Verify both elements: the external cause of diabetes and the explicit documentation of diabetic amyotrophy.
