A major antitrust lawsuit involving MultiPlan (now Claritev) and several top insurers is making waves in the healthcare industry. The MultiPlan lawsuit challenges how out-of-network (OON) reimbursement rates are set, and the outcome could significantly affect how providers are paid.
At Park Medical Billing, we stay ahead of these developments so our clients can remain compliant, financially secure, and informed.
Background: What the Lawsuit Is About
MultiPlan serves as a pricing intermediary for many insurers, helping determine OON reimbursement rates. The MultiPlan lawsuit led by healthcare organizations including the American Medical Association (AMA) alleges that MultiPlan and insurers shared pricing data to artificially lower OON payments.
A federal judge has allowed the case to move forward, meaning discovery and further review are underway. Some providers claim that their reimbursements were drastically below fair market rates, potentially harming thousands of practices across the U.S.
Why It Matters to Providers
This litigation could influence how payors handle out-of-network payments for years to come. Here’s what it means for your practice:
- Audit Your OON Reimbursements – Evaluate whether past claims show patterns of underpayment or algorithm-based rate suppression.
- Strengthen Negotiation Power – A favorable ruling could enhance providers’ leverage in future OON contracts and appeals.
- Maintain Tight Documentation – Complete, accurate billing records and CPT coding are key to defending payment rates and minimizing denials.
- Be Transparent with Patients – Keep patients informed about OON coverage, potential balance billing, and cost expectations.
What You Can Do Now
Take proactive steps to protect your practice:
- Review historical OON payments and identify anomalies.
- Ensure coding and documentation accuracy for all claims.
- Update financial consent and OON disclosure forms.
- Monitor payor communications for policy changes.
- Coordinate with your billing partner to stay compliant and responsive.
