An insurance carrier cannot use a general exclusion barring coverage for in-school treatment to disclaim coverage for autism-related services, the state Supreme Courthas ruled.

In a 4-1 decision in Burke v. Independence Blue Cross issued Thursday, the justices determined that, although the Autism Insurance Act, or Act 62, was ambiguous, the General Assembly did not intend to allow carriers to bar site-specific coverage for autism-related services. The ruling affirmed a decision from the state Superior Court.
