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.
Case period:
Published by The Dispute Index editorial teamPublished Updated
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.

EFF argues that automated decisions about government benefits and rights can create problems involving bias, due process and accountability.
"By outsourcing decision-making to private AI companies without sufficient transparency, testing, or legal limits, WISeR jeopardizes seniors’ access to medical care. Congress should step in to place greater legal limits on the use of automated decision-making in Medicare."
