What This Code Means

Type 1 diabetes with nerve damage from diabetes, but the specific type of nerve involvement is not specified.

Coding Tips

• •Use only when the type of diabetic neuropathy cannot be determined from the record

Clinical Significance

Type 1 diabetes mellitus with diabetic neuropathy, unspecified indicates nerve damage from Type 1 diabetes where the specific type of neuropathy has not been determined or documented. Diabetic neuropathy affects approximately 50% of people with long-standing diabetes and is the primary risk factor for foot ulceration and amputation. The 'unspecified' designation should prompt clinical evaluation and provider query to determine the neuropathy pattern for targeted management.

Documentation Requirements

• ✓Type 1 diabetes must be confirmed.
• ✓Documentation should describe neuropathy symptoms including location, type (sensory, motor, autonomic), and severity.
• ✓A provider query should be issued to determine if the neuropathy can be more specifically classified as polyneuropathy, mononeuropathy, autonomic neuropathy, or amyotrophy.
• ✓Nerve conduction study or monofilament testing results should be referenced when available.
