Whether your insurance covers weight loss surgery depends more on your zip code than your BMI. Only 23 states mandate some form of bariatric surgery coverage, and even within those states, the mandates vary dramatically in what they require, who they apply to, and what hoops you have to jump through.
The mandate landscape
States with bariatric surgery mandates fall into three categories: strong mandates (requiring coverage for all fully-insured plans with clear qualification criteria), limited mandates (requiring coverage only for state employee plans or specific conditions), and no mandate (insurers can exclude bariatric surgery entirely).
The self-funded loophole
State mandates only apply to fully-insured plans regulated by state insurance departments. Self-funded employer plans (governed by federal ERISA law) are exempt from state mandates. Roughly 65 percent of workers with employer-sponsored insurance are in self-funded plans — meaning the majority of employed Americans are not protected by state bariatric mandates regardless of which state they live in.
If your state doesn't mandate coverage
Your options: appeal the denial using ASMBS (American Society for Metabolic and Bariatric Surgery) clinical guidelines, request an external review if available under your plan, explore employer plan amendments (HR departments can add bariatric coverage to self-funded plans), switch plans during open enrollment to one that includes bariatric coverage (check the marketplace), or go abroad.
At $4,500 to $6,500 in Colombia versus $16,000 to $25,000 cash-pay in the US, the math for medical tourism is strongest in the bariatric category — because the US cash-pay price is inflated by the same facility and anesthesia overhead that makes insured pricing so high, and Colombian bariatric programs include nutritional counseling and psych evaluation that US cash-pay quotes often charge separately for.

Does Medicaid cover bariatric surgery?
Medicaid coverage for bariatric surgery varies by state. Roughly 24 states cover it under Medicaid with specific criteria. Check your state Medicaid program's covered services list.
What BMI do I need for insurance to cover bariatric surgery?
The standard criteria (when covered) are BMI ≥ 40, or BMI ≥ 35 with at least one obesity-related comorbidity (type 2 diabetes, hypertension, sleep apnea). Most plans also require 3 to 6 months of documented supervised diet failure.
