ICD-10 Code E13.43 – Other specified diabetes mellitus with diabetic autonomic (poly)neuropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.43 – Other specified diabetes mellitus with diabetic autonomic (poly)neuropathy
What it is
This code identifies diabetes from another specified cause, with documented autonomic nerve damage and polyneuropathy. Use it when the record links the neuropathy to the diabetes and specifies this diabetes category.
Clinical signs
Clinical features vary; refer to documentation. Autonomic involvement may affect involuntary body functions, while polyneuropathy can cause symmetric sensory or motor nerve symptoms in more than one limb.
When to use this code
Use E13.43 when the provider documents other specified diabetes mellitus and explicitly states diabetic autonomic neuropathy with polyneuropathy. The note should support a causal relationship between the diabetes and the neuropathic findings.
Choose this code for coding from the medical record, not from suspicion alone. If the diabetes type or neuropathy relationship is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for diabetes with neuropathy when the diabetes is type 1, type 2, or gestational. Do not use it if autonomic neuropathy or polyneuropathy is not documented as diabetic.
Coding tip
Confirm both the diabetes category and the specific neuropathy type in the provider note before coding E13.43.
