ICD-10 Code E13.44 – Other specified diabetes mellitus with diabetic amyotrophy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.44 – Other specified diabetes mellitus with diabetic amyotrophy
What it is
This code identifies diabetes mellitus that is not classified elsewhere and is complicated by diabetic amyotrophy, a painful neuropathic syndrome affecting the thigh, hip, or pelvic muscles. It signals a specific diabetic complication rather than uncomplicated diabetes.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include proximal muscle weakness, pain, and muscle wasting, often with asymmetric lower-extremity involvement and difficulty rising or walking.
When to use this code
Use E13.44 when the record documents other specified diabetes mellitus with diabetic amyotrophy. Apply it when the provider clearly links the neuropathic muscle weakness or pain to diabetes and does not describe a different diabetic complication.
If the note only says diabetes with neuropathy, check documentation before coding. This code is for diabetic amyotrophy specifically, not for generalized diabetic neuropathy or unspecified muscle weakness.
Do not use for
Do not use this code for uncomplicated diabetes, diabetic neuropathy without amyotrophy, or muscle symptoms not documented as diabetic in origin. Check documentation if the complication is unclear.
Coding tip
Look for provider wording that directly ties amyotrophy to diabetes; if the relationship is not explicit, query before assigning E13.44.
