ICD-10 Code E13.41 – Other specified diabetes mellitus with diabetic mononeuropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.41 – Other specified diabetes mellitus with diabetic mononeuropathy
What it is
This code identifies diabetes mellitus due to other specified causes when the patient also has diabetic mononeuropathy. Use it when the record links a single peripheral nerve problem to diabetes, but the diabetes type is not one of the standard categories.
Clinical signs
Findings usually reflect dysfunction of one nerve, such as focal pain, numbness, weakness, or loss of sensation in a limited distribution. Clinical features vary; refer to documentation.
When to use this code
Use E13.41 when the provider documents diabetes from another specified cause and clearly states mononeuropathy as a diabetic complication. The note should connect the nerve disorder to the diabetes. If the type of diabetes or the neuropathy relationship is unclear, check documentation.
Do not use for
Do not use this code for generalized diabetic polyneuropathy, autonomic neuropathy, or neuropathy not documented as diabetic. Also avoid it when the diabetes type is better captured by another ICD-10 category.
Coding tip
Assign the diabetes code only when the chart explicitly links the mononeuropathy to diabetes and specifies the “other specified” diabetes category.
