SPRINGFIELD, Ill. (AP) -- The Illinois House is receiving its fifth piece of legislation this year requiring insurance coverage for autism treatment.

The Senate voted 47-6 Tuesday to approve the plan. It would require insurers to cover up to $36,000 a year and unlimited doctor visits until age 21 for people with autism spectrum disorders.

The Senate has previously sent three bills on the matter to the House. Governor Rod Blagojevich added the language to two other bills in amendatory vetoes.

The House likes the idea, but some lawmakers say they don't trust Blagojevich to implement the plan without legislative oversight.
