CMS Updates Section 111 Model Language Form

Recently, the Section 111 Model Language form was updated by the Centers for Medicare and Medicaid Services (CMS), The form is used by Responsible Reporting Entities (RREs) to collect the Medicare Beneficiary Identifier (MBI) and/or a Social Security Number (SSN) from claimants.  The SSN or MBI, along with the claimant’s First and Last Name, Gender, and Date of Birth, are needed by the RRE to query CMS to determine whether the claimant is a Medicare beneficiary for Section 111 Mandatory Insurer Reporting purposes.

The most notable change to the form is that the Section I language was revised from “Are you presently, or have you ever been, enrolled in Medicare Part A or Part B?” to “Are you presently, or have you ever been, enrolled in Medicare?” We assume this language was modified because the claimant’s enrollment in Parts A, B, or C (which isn’t even mentioned) is irrelevant for purposes of Section 111 reporting. The simpler language, just asking for Medicare enrollment status, should avoid confusion that may have arisen from the prior language.

Practical Implications of the Section 111 Model Language form

As we wait for CMS to issue final rules around mandatory insurer reporting penalties, it is important for RREs and those administering claims for RREs to collect this identifying information or document their efforts to collect it by using this model language.  As we discussed in CMS Issues Proposed Rule for Mandatory Insurer Reporting Penalties, RREs will have a safe harbor from reporting penalties if they document good faith efforts to attempt to obtain an MBI or SSN from the claimant, and this model form will help document those efforts.
