What This Code Means

Diabetes caused by medications or chemicals with nerve damage (neuropathy) that is not further specified.

Coding Tips

• •Query provider to determine if neuropathy type can be specified (peripheral, autonomic, mononeuropathy, etc.)
• •Document symptoms and affected areas to support more specific coding if available

Clinical Significance

Drug or chemical induced diabetes mellitus with diabetic neuropathy, unspecified indicates nerve damage from drug-induced diabetes where the specific type of neuropathy has not been determined. Diabetic neuropathy affects up to 50% of patients with long-standing diabetes and can involve sensory, motor, or autonomic nerves. The 'unspecified' designation should prompt further clinical evaluation to determine the neuropathy pattern for appropriate management.

Documentation Requirements

• ✓The causative drug or chemical must be documented.
• ✓Provider notes should describe the neuropathy symptoms and distribution.
• ✓A query should be issued to determine if the neuropathy is peripheral polyneuropathy, mononeuropathy, autonomic neuropathy, or another specific type.
• ✓Nerve conduction studies or electromyography results, if performed, should be referenced.
