Highmark Health sues HaloMD over alleged sham arbitration letter and misleading price data

Highmark Health, a Pennsylvania Blue Cross Blue Shield licensee with more than 7 million members, filed a complaint on June 1 in U.S. District Court in Western Pennsylvania accusing HaloMD of abusing the No Surprises Act arbitration process.

The complaint alleges that HaloMD and its client, neuromonitoring provider Bromedicon, sent arbitrators a “sham letter” and false price data, leading to more than 450 disputes that were ineligible under the law.

According to Highmark, those disputes resulted in arbitration awards totaling over $3.9 million, which the insurer wants vacated and the funds returned.

Highmark is the fourth major insurer to sue HaloMD, joining three other Blue Cross plans that have challenged similar arbitration wins, raising questions about the credibility of the arbitration mechanism used for surprise‑billing disputes.
