OLYMPIA, Wash. -

The board for the state health exchange once has again delayed a vote on approval of 31 plans proposed to be part of the system.

The board voted Thursday to delay the vote until next Wednesday, when they had already had scheduled a meeting to consider additional companies that are appealing exclusion by Washington's insurance commissioner.

Earlier this month, Insurance Commissioner Mike Kreidler approved four insurance companies to join the exchange and rejected proposals by five others because their plans didn't fit all the rules set up by the federal government.

Some of those companies have appealed Kreidler's decision and are in the middle of an appeals process.

Michael Marchand, spokesman for the exchange, has said that the delay in finalizing insurance plans for Washington will not affect the state's open enrollment period, set to begin Oct. 1.
