Starting in 2014, all 100 U.S. senators, 435 representatives in the House and their aides will have to get their health insurance through ObamaCare’s newly formed state exchanges. But they won’t see a spike in their health care costs under a deal struck before the August recess.

Congressional leadership aides tell Fox News a deal has been reached with the Office of Personnel Management, which will allow the government to continue to make employer contributions to the health plans of lawmakers and congressional staffers.

The OPM, which oversees the compensation system for the federal civilian workforce, is expected to issue guidance next week to spell out a way to fix the issue.

Lawmakers and their staff currently select their health insurance plan from the pool of health care policy options that are available to all federal employees. Under ObamaCare, they will be required to purchase their insurance from the state-run exchanges.
