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

This series has made the affirmative case for geographic arbitrage with genuine enthusiasm. Domestic steering to lower-cost facilities (LFP-10.03), cross-border care at JCI-accredited hospitals (LFP-10.04), and international pharmacy purchasing (LFP-10.05) collectively represent the largest single cost management opportunity in level funded plans. The savings are real. The risks are also real, and the series articles may understate them.

This companion argues the countercase with equal rigor. Geographic arbitrage carries complications that erode savings, liability exposure that is largely untested, local provider resistance that creates continuity problems, and member trust consequences that can damage the plan’s relationship with its covered population. None of these risks make geographic arbitrage categorically inappropriate. All of them constrain where, when, and for whom the strategy is defensible.

The Complication Risk

#

A member who undergoes total knee replacement at a JCI-accredited hospital in Monterrey and develops a surgical site infection after returning to Denver faces a specific clinical problem. The Denver emergency department physician managing the infection does not have the operative record. The physician does not know which prosthetic components were implanted, what surgical approach was used, what antibiotics were administered prophylactically, or whether intraoperative cultures were obtained. The member may not remember these details or may not understand the clinical significance of what they were told.

Published research documents this information transfer gap. A PMC study found that incomplete medical records hinder continuity of care after medical travel, and that many surgeons are apprehensive about accepting complications from another surgeon’s patient. The CDC’s 2026 Yellow Book warns that medical tourists may not have the same legal recourse as those who receive care domestically. The Aerospace Medical Association recommends waiting one to two weeks before flying after surgery because air travel compounds the already elevated blood clot risk from surgical procedures.

A 2024 study in Aesthetic Surgery Journal Open Forum examined 41 patients treated for complications following plastic surgery tourism. Infection (51%) and seroma (56%) were the most common complications. Patients requiring admission needed intravenous antibiotics (42.9%) and at least one additional operation (64.3%). Complication management costs ranged from $26,000 to $154,000. These figures involve cosmetic procedures at unaccredited facilities, not JCI-accredited orthopedic hospitals. The complication profile differs. The information transfer gap does not.

The American Society for Metabolic and Bariatric Surgery advises that extensive surgical travel should be discouraged unless appropriate follow-up and medical information transfer are ensured. The American College of Surgeons recommends obtaining complete medical records before returning home. Geographic separation between operating facility and follow-up provider creates a coordination problem that must be solved, not assumed away.

The Liability Exposure

#

When a TPA recommends that a member travel to a hospital in Mexico City for an elective procedure and the member suffers a complication, the liability questions are substantial and largely untested in case law.

The international facility may have limited malpractice coverage enforceable in US courts. Medical malpractice law varies by country, and judgments obtained in Mexican or Costa Rican courts may be difficult to enforce and may cap damages at levels far below US standards. The CDC explicitly warns that patients who receive care abroad may not have the same legal recourse as those who receive care domestically.

The TPA that recommended the facility faces potential claims of negligent referral. If the TPA vetted the facility, represented it as safe, and the member relied on that representation in choosing to travel, the TPA has arguably assumed a duty of care in the referral. The scope of that duty is not well defined in existing ERISA case law. The TPA’s defense that it merely provided information differs from the member’s experience that the plan actively steered them to an international facility and provided financial incentives to go.

The plan sponsor faces ERISA fiduciary liability questions. A fiduciary that designs a benefit structure incentivizing international care has made a plan design decision that, if it results in harm, could trigger breach claims under ERISA Section 502(a)(2). That argument may not prevail, but defending it is expensive and the reputational damage is real.

The legal framework for cross-border medical liability in employer-sponsored plans is largely untested because the practice remains uncommon. That absence of precedent is itself a risk. For a small employer with 25 employees and personal relationships with every covered member, the reputational consequence of a serious complication at a facility the plan recommended differs in kind from a complication at the member’s local hospital.

The Local Provider Problem

#

Local providers may resist managing post-operative care for procedures performed elsewhere. The orthopedic surgeon in the member’s home market whose patient went to Mexico for a knee replacement instead of having it done locally has both clinical and economic reasons to be reluctant. Clinically, the surgeon is assuming responsibility for managing an outcome they did not create, with a prosthetic they may not have experience with, using a surgical approach they did not choose. Economically, the surgeon lost a revenue-generating procedure to a competitor facility. The surgeon may accept the patient out of professional obligation but is unlikely to be enthusiastic about managing complications from a procedure performed at a facility that undercut their pricing.

This provider resistance is documented in the literature. A surgeon who manages a complication from another surgeon’s procedure and the outcome is poor faces the possibility that the patient attributes the poor outcome to the follow-up care rather than the original surgery. The liability exposure runs in both directions.

For a level funded TPA implementing a geographic arbitrage strategy, the local provider problem requires a proactive solution. Pre-established agreements with local providers to manage post-operative care from designated facilities, including information transfer protocols and financial arrangements that compensate the local provider for the complexity of managing another surgeon’s patient, are necessary. Without these agreements, the member who returns home with a complication faces the prospect of presenting to an emergency department as an unscheduled patient, receiving fragmented care from physicians with no context, and generating the exact high-cost, low-quality utilization the arbitrage strategy was designed to avoid.

The Guardrails That Make It Defensible

#

Geographic arbitrage is defensible for the right procedures, the right patients, and with the right infrastructure. The guardrails that separate defensible arbitrage from reckless cost-cutting are specific.

Procedure selection criteria must be strict. Appropriate procedures are elective (the patient can choose timing), scheduled (not emergent), standardized (the surgical technique is well established with minimal variation between competent surgeons), low complication rate (the probability of requiring local follow-up for complications is small), and the patient can manage recovery independently or with a companion. Joint replacement, cataract surgery, dental implants, hernia repair, and selected spine procedures meet these criteria. Complex oncology surgery, transplant, procedures requiring extended inpatient monitoring, any emergency care, and procedures with high complication rates do not.

Accreditation requirements must include JCI as the minimum standard, with facility-specific outcome data reviewed before any patient is referred. JCI accreditation confirms compliance with international patient safety standards but does not guarantee individual surgical outcomes.

Complication management protocols must be written and agreed to before the first patient travels. These protocols specify information transfer requirements (operative records, implant specifications, pathology results), financial responsibility for complication management, and communication channels between the international facility and the local follow-up provider. Local follow-up arrangements must be pre-established, not arranged after a complication occurs.

Member consent must be informed and voluntary. The plan can provide financial incentives for choosing a lower-cost facility but should not create penalties that effectively coerce the member into traveling. A benefit design that waives the deductible for care at a designated facility is an incentive. A benefit design that imposes a 50% coinsurance penalty for choosing a local hospital is coercion.

These guardrails do not eliminate risk. They reduce it to a level where the savings justify the residual exposure for appropriate procedures and patients. A TPA that implements geographic arbitrage without complication protocols, without pre-established local follow-up, and without informed consent is not managing cost. It is transferring risk from the claims fund to the member.
