Summary
This policy establishes coverage criteria for antibody tests used to diagnose neurologic diseases including peripheral neuropathies, paraneoplastic syndromes, and conditions like Guillain-Barre syndrome and Miller-Fisher syndrome. The policy provides detailed medical background on when specific antibody tests (GM1, MAG, anti-Hu, etc.) are considered appropriate for diagnosis of various neurologic conditions.
Action Required
Review policy L.2.04.400 for antibody tests in neurologic diseases to understand coverage criteria. Ensure providers document appropriate clinical indications (paresthesias, weakness, twitching, suspected paraneoplastic syndromes) when ordering antibody tests for neurologic conditions. Verify that antibody testing is used selectively rather than as screening studies, as the policy emphasizes directed approach over broad screening.
