On July 13, 2015, CMS issued an updated Section 111 NGHP User Guide. In an effort to prevent false positives in partial SSN searches, CMS increased the number of additional criteria needed to return a match. When submitting a beneficiary using a partial SSN of five digits, all four of the remaining criteria- first initial, surname, date of birth, and gender- must now be matched exactly.
Additionally, the new User Guide replaces the term “TPA” with “recovery agent” and provides dedicated fields for RREs to submit recovery agent information on the TIN reference file. The Section 111 URL was also changed to https://www.cob.cms.hhs.gov/Section111/LoginWarning.action.
