"It now takes 48 days to see an internist for a routine checkup," Pitts said. "Premiums in Massachusetts remain among the highest in the nation. Low reimbursements in the Commonweatlh Care health plan mean that only about half of doctors accept the state-managed insurance.

"Far from solving Massachusetts' healthcare crisis, the health reform law has created problems of its own," Pitts continued. "The Massachusetts Medical Society finds that the environment for physicians continues to deteriorate despite billions in government spending, just a sample of what awaits the nation under Obamacare."

Pitts' comments are another reminder of the Republican opposition to state-mandated healthcare plans, which could pose problems for GOP presidential candidate Mitt Romney. As Massachusetts governor, Romney in 2006 signed the statewide healthcare plan into law, which required all Massachusetts residents to buy health insurance.

Romney is expected to deliver a speech Thursday outlining how he would replace last year's healthcare law.
