HARRISBURG, Pa. (AP) — Top aides to Pennsylvania Gov. Tom Corbett plan to meet Monday with officials from the Centers for Medicare and Medicaid Services, the first such meeting since he released his plan to use federal Medicaid expansion dollars to extend health insurance to hundreds of thousands of the working poor.

The meeting comes amid criticism that Corbett's plan will leave people uninsured when the extra Medicaid money becomes available Jan. 1. The plan released Monday by Corbett, a Republican and critic of Medicaid, will require potentially lengthy negotiations with the federal government to sort out changes Corbett wants to the Medicaid expansion envisioned by President Barack Obama's signature health care law.

Even if those changes are approved by the federal government, a process including time for public comment, some analysts doubt that every element of Corbett's plan will receive approval, but administration officials aren't saying how they will respond or whether they are open to compromise.
