The Association of New Jersey Chiropractors (ANJC) has officially joined a sweeping federal antitrust lawsuit against data analytics giant MultiPlan and several major insurance companies, including UnitedHealth, Aetna, Cigna, and Humana. The core allegation of this multidistrict litigation is that these entities conspired in a coordinated price-fixing scheme to deliberately and systematically underpay healthcare practitioners for out-of-network services. According to the ANJC, these reimbursements have become so insufficient they often fail to cover basic operating costs. The lawsuit, which consolidates claims from the American Medical Association and hundreds of other medical practices, seeks to end this alleged illegal collusion and recover financial damages for underpayments dating back to at least 2015. The case has gained significant momentum, having received a statement of interest from the U.S. Department of Justice and surviving a motion to dismiss, which now allows the litigation to proceed to the discovery phase. This legal action represents a critical step for practitioners seeking fair reimbursement and an end to anticompetitive practices that harm both providers and patients.
