Q&As: Specialty Pharmacy Access and Best Available Data

Please see the attached Q&As regarding Specialty Pharmacy Access and Best Available Data. Thank you.

Specialty Pharmacy Access: Q. Can Part D plans restrict access to certain Part D drugs to "specialty" pharmacies within their Part D networks?

Best Available Data: Q. CMS instructed Part D plans on May 5, 2006 that they are required to use the "best available data" to make changes to their systems when they have knowledge that a dual eligible beneficiary's cost sharing level is not correct. What does CMS mean by best available data?
