NASHVILLE, Tenn. (AP) -- A proposal that would allow Tennessee to join an interstate compact challenging the federal health care law has been approved by the House after the chamber approved several changes sponsored by Democrats.

The measure sponsored by Republican Rep. Mark Pody of Lebanon was approved on a 63-27 vote on Tuesday.

The companion bill passed the Senate 22-9 last year, but the upper chamber would have to agree to the changes before the measure could head for the governor's consideration.

The legislation would provide a waiver for each participating state to create its own health care system. Sponsors say the proposal is intended to give Tennesseans more choices concerning health care if the compact were approved by Congress.

The main change approved Tuesday would make Tennessee's participation in the compact optional.
