"From their perspective, they're basically saying to us, what incentive do they have to enroll," said Morse, the head of program integrity for CMS.
Part D, which began in 2006, has received high marks from patients. It now covers more than 42 million people. But experts have long complained that the program places a higher priority on getting prescriptions into patients' hands than on targeting problem prescribers. The Department of Health and Human Services' inspector general has repeatedly called for tighter controls.
In 2013, ProPublica documented how Medicare's failure to oversee Part D effectively had enabled doctors to prescribe inappropriate or risky medications, had led to the waste of billions of dollars on needlessly expensive drugs, and had exposed the program to rampant fraud. At the time, Medicare said it had no authority to take action against doctors or other providers even if it found their prescribing practices troubling.
Medicare's response, finalized in May 2014, gave officials the power to kick health providers out of the program if their prescribing is abusive, a threat to public safety or in violation of Medicare rules. CMS said it would use prescribing data, disciplinary actions, malpractice lawsuits and more to identify problem providers.
To date, officials said, Medicare has only done so once.
But the plan to require that providers enroll in Medicare has been met by delay after delay after delay.
At first, CMS gave providers until June 1, 2015, to either enroll in Medicare or formally opt out. Either way, the government would have additional information about them. If they neither enrolled nor formally opted out, Medicare said it would no longer cover drugs they ordered for beneficiaries.
