Yesterday, CMS issued a technical alert regarding the partial use of SSNs. As mentioned in our prior blog, CMS had recently become aware that the submission of partial SSNs was erroneously causing the return of false positives in matches with regard to Medicare eligibility.
The new alert dated June 18, 2015 essentially provides that in order to determine if individuals are Medicare beneficiaries, the following information will be utilized by CMS: HICN or SSN, first initial of the first name, first 6 characters of the last name, date of birth (DOB), and gender. Effective immediately, the matching criteria for partial SSNs is changed. When an exact match on the partial SSN is found, then four out of the four remaining data elements must be matched to the individual exactly. The matching criteria for HICNs and full SSNs will remain the same.
CMS has continued to advise that where a full SSN is available, RREs should submit full SSNs to ensure the most accurate match is attained.
