Inflammatory polyneuropathy, unspecified

This code represents a general diagnosis for inflammation affecting multiple peripheral nerves throughout the body, where the specific type or cause of the polyneuropathy has not been identified. It indicates a diffuse neurological disorder characterized by sensory, motor, or autonomic dysfunction due to widespread nerve inflammation.

Use this code when the medical record clearly documents an inflammatory polyneuropathy but lacks further specificity regarding its etiology (e.g., acute, chronic, demyelinating, axonal, or autoimmune type). This is appropriate for initial encounters or when diagnostic workup is incomplete and a more precise diagnosis cannot yet be assigned. Documentation should support the inflammatory nature of the polyneuropathy.

• Avoid using this code if a more specific type of inflammatory polyneuropathy (e.g., Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy [CIDP]) is documented.
• Always query the provider for greater specificity if possible, as more precise codes exist for various inflammatory polyneuropathies.
• This code should be used as a last resort when no other specific inflammatory polyneuropathy code can be assigned based on available documentation.
