What This Code Means

Type 2 diabetes with damage to multiple nerves (polyneuropathy), typically affecting both sides of the body symmetrically. This commonly causes numbness, tingling, or weakness in the feet and hands.

Coding Tips

• •Polyneuropathy is the most common form of diabetic neuropathy; document the distribution and severity when documented
• •Consider if patient has symptoms in multiple extremities to differentiate from mononeuropathy

Clinical Significance

Type 2 diabetes mellitus with diabetic polyneuropathy is the most prevalent form of diabetic neuropathy, affecting both sides of the body symmetrically in a 'stocking-glove' distribution. This condition causes progressive numbness, tingling, burning pain, and loss of protective sensation in the feet and hands. It is the leading predisposing factor for diabetic foot ulcers and non-traumatic lower extremity amputations, making it one of the most clinically significant diabetic complications.

Documentation Requirements

• ✓Documentation must confirm polyneuropathy as a complication of Type 2 diabetes, describing the distribution pattern, severity, and functional impact.
• ✓Neurological examination findings including monofilament testing, vibration perception, ankle reflexes, and pain assessment should be recorded.
• ✓Nerve conduction study results, if performed, should be included.
• ✓Foot care plans and neuropathic pain management should be documented.
