ICD-10 Code E13.49 – Other specified diabetes mellitus with other diabetic neurological complication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.49 – Other specified diabetes mellitus with other diabetic neurological complication
What it is
This code identifies diabetes mellitus from another specified cause, with a neurological complication that is not classified elsewhere. Use it when the record links the diabetes to a nerve-related problem and a more specific code is not available.
Clinical signs
Clinical features vary; refer to documentation. Neurological complications may include neuropathic pain, numbness, tingling, weakness, or other nerve dysfunction attributed to diabetes.
When to use this code
Use E13.49 when the provider documents other specified diabetes mellitus and a diabetic neurological complication, but does not name a more specific manifestation. It is appropriate when the chart clearly connects the neurologic problem to diabetes. Check documentation if the type of diabetes or complication is unclear.
Do not use for
Do not use this code for diabetes without a documented neurological complication. Also avoid it when the record supports a more specific diabetic neurologic code or when the diabetes type is not “other specified.”
Coding tip
Confirm both the diabetes category and the neurologic complication are documented together before assigning E13.49.
