WASHINGTON (AP) _ House conservatives pushing $90 billion in cuts in Medicare and other programs are denying White House charges that the package will weaken the military and jeopardize President Clinton's health plan.

''In order to have change, you've got to turn around and walk in the other direction, and that's what I'm trying to do,'' Rep. John Kasich, R-Ohio, an author of the spending-cut plan, said Friday.

The House plans to vote Monday on the proposed cuts, which were pieced together by Kasich, Rep. Tim Penny, D-Minn., and about 30 other conservatives from both parties.

The five-year savings package would trim spending in dozens of programs, paring everything from Congress' own operations to federal retirees' benefits to subsidies for public housing.

The plan's opponents, who are mostly Democrats, fear the House will approve the measure in an atmosphere in which many voters are demanding spending cuts. They may have to count on the Senate killing it next year.

But in hopes of heading off the measure in the House, the White House escalated attacks against it.

''Don't vote to undercut our efforts at health care reform and protecting the national security,'' White House budget chief Leon Panetta told reporters in remarks aimed at House members.

At a White House briefing, Panetta and Defense Secretary Les Aspin said cuts in federal jobs and pensions for some retirees the conservatives proposed would hit the military hard.

These provisions would break faith with the men and women in our military, and seriously threaten the readiness of our forces,'' Aspin said.

Panetta said the $40 billion in Medicare reductions the conservatives have proposed would ''blow a major hole'' in Clinton's health-care package. That is because it would make it harder for the administration to get $124 billion in savings from the medical insurance program for the elderly to help finance its health plan.

Conservatives contested the administration's accusations.

''All of these people know better, and they just want to throw dust in the air as a way of giving members pause'' about supporting the Penny-Kasich plan, Penny said.

The House is also expected to vote Monday on a smaller plan, offered by the administration and Democratic leaders, aimed at trimming about $30 billion.

Most of its savings would come from eliminating 252,000 jobs from the federal work force, as was suggested in Vice President Al Gore's report on government efficiency in September. Penny and Kasich included the jobs cuts in their plan, too.
