ICD-10 Code E13.8 – Other specified diabetes mellitus with unspecified complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.8 – Other specified diabetes mellitus with unspecified complications
What it is
E13.8 identifies a form of diabetes mellitus that is classified as “other specified” and has complications, but the complication is not described in the record. Use it when the diabetes type is documented, yet the complication details remain unspecified.
Clinical signs
Clinical features vary; refer to documentation. You may see signs of diabetes with a noted complication, but the chart does not name the affected organ, system, or complication type.
When to use this code
Use this code when the provider documents other specified diabetes mellitus and states there is a complication, but does not specify which one. It also fits when the record confirms a diabetic complication without enough detail to assign a more precise code. Check documentation if the complication is unclear.
Do not use for
Do not use this code when the diabetes type is not “other specified,” or when the complication is fully identified and a more specific code is available. Do not assign it if the record says diabetes without complications.
Coding tip
Query for the exact complication whenever the note mentions diabetes-related problems but leaves the complication unspecified.
