ICD-10 Code E13.9 – Other specified diabetes mellitus without complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.9 – Other specified diabetes mellitus without complications
What it is
E13.9 identifies diabetes mellitus that fits a specific “other specified” category and has no documented complications. Use it when the record names a qualifying diabetes type but does not describe kidney, eye, neurologic, or circulatory involvement.
Clinical signs
Clinical features vary; refer to documentation. You may see chronic hyperglycemia or a documented diabetes diagnosis without evidence of acute or chronic complications.
When to use this code
Use E13.9 when the provider documents diabetes mellitus in the “other specified” group and explicitly states there are no complications. It is appropriate when the chart supports the diagnosis but does not identify a more specific complication code. If the note is vague, check documentation before assigning the code.
Do not use for
Do not use this code if the diabetes is type 1, type 2, gestational, or due to another clearly coded cause. Also avoid E13.9 when any complication is documented, because a more specific code may be required.
Coding tip
Confirm the exact diabetes type and look for documented complications before selecting E13.9.
