CMS will continue to educate sponsors of Medicare Part D drug plans about the requirements for providers that wish to write electronic prescriptions and will keep working with the National Council for Prescription Drug Programs to update e-prescribing standards, according to the HHS Office of Inspector General. In its semiannual report to Congress, the OIG says that nearly 80 percent of plan sponsors surveyed in September 2008 had at least partially implemented NCPDP standards on e-prescribing communication between prescribers and plan sponsors, but few had completed implementation in the voluntary program. Many sponsors reported problems with the standard on formulary and benefits. Report (.pdf)
