Unspecified hereditary and idiopathic peripheral neuropathy

This code signifies a peripheral neuropathy of unknown origin or one inherited through genetic factors, where the specific type or cause has not been identified. It indicates a disorder affecting the peripheral nerves, leading to symptoms such as weakness, numbness, and pain, without a definitive diagnosis of the underlying etiology.

This code is appropriate when documentation clearly states "idiopathic peripheral neuropathy" or "hereditary peripheral neuropathy, unspecified." It should be used when the physician has diagnosed a peripheral neuropathy but has not yet determined if it's acquired, or if hereditary, the specific genetic defect remains unknown.

• Avoid using this code if a more specific type of hereditary or acquired neuropathy is documented (e.g., diabetic neuropathy, Charcot-Marie-Tooth disease).
• Query the provider for further specificity if the documentation only states "peripheral neuropathy" without specifying idiopathic or hereditary.
• This code is a "catch-all" for unspecified cases; strive for higher specificity whenever possible.
