Mononeuritis of unspecified site

This code signifies inflammation or damage to a single peripheral nerve, where the specific nerve affected is not documented. It represents a general diagnosis of mononeuropathy without further anatomical detail. This condition can lead to symptoms such as pain, numbness, tingling, or weakness in the distribution of the affected nerve.

Use this code when documentation clearly indicates mononeuritis but fails to specify the anatomical location (e.g., "mononeuritis," "unspecified mononeuropathy"). This code is appropriate when the physician has not identified the particular nerve involved or when the diagnostic workup is incomplete regarding the exact site.

• Avoid using this code if a more specific anatomical site of mononeuritis is documented (e.g., carpal tunnel syndrome, peroneal nerve palsy).
• Review the entire medical record for any clues regarding the specific nerve, even if not explicitly stated in the diagnosis.
• Query the provider for clarification on the specific nerve involved if possible, to allow for more precise coding.
