Question: What is the best diagnosis code for long thoracic nerve palsy?

Oregon Subscriber

Answer: You have two possibilities: 353.0 (Nerve root and plexus disorders; brachial plexus lesions) or 344.9 (Paralysis, unspecified).

The long thoracic nerve is part of the brachial plexus. When you check "Palsy" in ICD-9, the index directs you to also check "Paralysis." The diagnosis for brachial plexus paralysis is 353.0.

Another option: If 353.0 doesn't match your physician's documentation or the patient's signs and symptoms, your alternative diagnosis would be 344.9 (Paralysis, unspecified).
