Executive Summary: The Case Against Geographic Arbitrage: Complications, Liability, Follow-Up Care, and the Risks of Steering Members Away From Local Providers

LFP-10.C1 — The Cost Management Frontier

#

The savings from domestic steering, cross-border care, and international pharmacy purchasing are real. So are the risks, and the series articles may understate them.

Complication risk is the most concrete concern. A member who undergoes total knee replacement in Monterrey and develops a surgical site infection after returning to Denver faces an emergency physician who has no operative record, no knowledge of which prosthetic components were implanted, and no context for the surgical approach used. A 2024 study in Aesthetic Surgery Journal Open Forum found that 64.3 percent of patients treated for complications following surgical tourism required at least one additional operation, with complication management costs ranging from $26,000 to $154,000. Information transfer gaps affect accredited orthopedic facilities as well as unaccredited cosmetic ones.

Liability exposure for the TPA is largely untested. A TPA that vetted a facility, represented it as safe, and provided financial incentives for the member to travel has arguably assumed a duty of care in the referral whose scope is not defined in existing ERISA case law. Local provider resistance compounds the problem: orthopedic surgeons have both clinical and economic reasons to be reluctant about managing complications from procedures they did not perform.

Geographic arbitrage is defensible only with specific guardrails: elective, scheduled, standardized procedures with low complication rates; JCI accreditation as the minimum facility standard; written complication protocols and pre-arranged local follow-up before the first patient travels; and informed, voluntary member consent through financial incentives rather than penalties. A benefit design that waives the deductible at a designated facility is an incentive. One that imposes 50 percent coinsurance at a local hospital is coercion. Without these guardrails, the TPA is not managing cost. It is transferring risk from the claims fund to the member.
