EFF challenges Medicare's WISeR safeguards; CMS cites clinician review

EFF challenges safeguards in Medicare's AI-assisted WISeR review program after releasing vendor records. CMS says clinicians determine nonpayment recommendations and that the model does not change Medicare coverage or payment policy.

Overview

EFF's October 27 analysis (opens in a new tab) describes vendor problems and argues that clinical review needs stronger disclosure and legal limits. Its concerns include whether reviewers have enough time and authority to override automated recommendations.

CMS describes WISeR (opens in a new tab) as technology-assisted review with licensed clinicians determining nonpayment recommendations. Providers may choose prior authorization or post-service, pre-payment review. The model excludes emergency and inpatient-only services.

CMS's published model description supplies its policy rationale; it predates EFF's latest release.
