Neuralgic amyotrophy

Neuralgic amyotrophy, also known as Parsonage-Turner syndrome, is a rare neurological disorder characterized by sudden onset of severe pain in the shoulder and arm, followed by weakness and muscle wasting in the affected area. It typically involves the brachial plexus, leading to motor and sensory deficits.

This code is used when documentation clearly indicates a diagnosis of neuralgic amyotrophy, idiopathic or otherwise, affecting the brachial plexus or other peripheral nerves. It's appropriate for cases presenting with the characteristic pain, weakness, and subsequent atrophy not attributable to trauma or other specific underlying conditions.

• Ensure documentation specifies "neuralgic amyotrophy" and not a general neuropathy.
• Carefully review for any mention of diabetes mellitus; if present, a different code combination is required.
• Do not use for general brachial plexopathy without the specific diagnosis of neuralgic amyotrophy.
