Other mononeuritis of upper limb

This code represents inflammation or damage to a single peripheral nerve in the upper extremity, excluding conditions specifically classified elsewhere. It encompasses various forms of mononeuropathy affecting the arm, forearm, or hand, not limited to common entrapment syndromes.

Use this code for documented cases of mononeuritis of the upper limb where a more specific ICD-9 code is not available. This includes conditions like brachial neuritis (Parsonage-Turner syndrome) or other inflammatory neuropathies affecting a single upper limb nerve, supported by neurological examination findings and diagnostic studies.

• Ensure documentation clearly specifies "mononeuritis" and its location in the upper limb.
• Differentiate from polyneuropathies or generalized neuropathies, which have different code assignments.
• Always look for more specific codes first (e.g., carpal tunnel syndrome, ulnar nerve entrapment) before defaulting to this code.
