"These efforts are ensuring that only qualified and legitimate providers and suppliers can provider healthcare products and services to Medicare beneficiaries," CMS said in a memo.
The agency also touted redesigned Medicare statements that will help seniors spot fraudulent billings more easily.
Beneficiaries will receive the documents every quarter and are eligible for rewards in exchange for tips about suspected fraud.
"Unfortunately, there are some people trying to exploit the Medicare system," said Peter Budetti, CMS deputy administrator for program integrity, in a statement.
"A beneficiary's best defense against fraud is to check their Medicare Summary Notices for accuracy and to diligently protect their health information for privacy."
