Key legal question
Whether IV must cover investigation and treatment of an alleged heavy-metal burden through chelation therapy.
Extracted holding
The claimed heavy-metal testing and chelation therapy were not covered because no scientifically established causal link with autism was shown and the therapy was not indicated.
Extracted reasoning
The medical evidence did not show a scientifically sufficient connection between elevated heavy-metal levels and autism; the measured values were largely normal, and chelation was considered controversial and risky.
