Other specified mononeuropathies

This code signifies a mononeuropathy affecting a single peripheral nerve that does not fit into more specific categories of mononeuropathies (e.g., carpal tunnel syndrome, ulnar neuropathy). It indicates a distinct nerve dysfunction with an identified cause or location, but one that is not commonly classified or has unique features.

Use this code when documentation clearly specifies a mononeuropathy that is not otherwise classified in ICD-10-CM, such as a peroneal nerve entrapment not specified as common, or a specific nerve injury from trauma not covered by more precise codes. Supporting documentation must identify the affected nerve and confirm it's a mononeuropathy.

• Avoid using this code if a more specific mononeuropathy code exists (e.g., G56.0- for carpal tunnel).
• Ensure the documentation specifies the affected nerve and the "other specified" nature of the condition.
• Consider sequencing this code after a code for the underlying cause if applicable (e.g., trauma, systemic disease).
