What This Code Means

Type 2 diabetes with nerve damage (neuropathy) that is not further specified. This occurs when high blood sugar levels damage nerves throughout the body.

Coding Tips

• •Use this code only when the type of diabetic neuropathy is not documented; if specific neuropathy type is identified, use more specific codes E11.41-E11.49
• •Always verify that Type 2 diabetes is confirmed in the diagnosis before coding; do not assume based on patient age or presentation

Clinical Significance

Type 2 diabetes mellitus with diabetic neuropathy, unspecified, indicates nerve damage from diabetes where the specific type of neuropathy has not been further characterized. Diabetic neuropathy affects approximately 50% of patients with long-standing diabetes and is the primary risk factor for diabetic foot ulceration and amputation. Even without type specification, documentation of neuropathy signals the need for foot care programs, pain management, and fall prevention strategies.

Documentation Requirements

• ✓Documentation must confirm diabetic neuropathy in a Type 2 diabetic patient.
• ✓Neurological examination findings including sensory testing (monofilament, vibration), reflexes, and motor function should be recorded.
• ✓Providers should be queried to specify the neuropathy type (peripheral, autonomic, mononeuropathy, polyneuropathy) to enable more precise coding.
• ✓Treatment with neuropathic pain medications should be noted.
