A new law in Delaware requires that individual health insurance plans provide coverage for the diagnosis and treatment of autism spectrum disorders.

Legislation being signed by Gov. Jack Markell on Monday requires coverage and treatment of autism spectrum disorders in individuals under 21 years old.

The law also prohibits insurers from terminating or refusing to renew coverage to an individual solely because the individual or a family member is diagnosed with one of the autism spectrum disorders or has received treatment for autism spectrum disorders.
