Some procedures are not denied because of a technicality — they are excluded by design. Your policy was written to never pay for them. No appeal, no peer-to-peer review, no external reviewer will change the outcome because the exclusion is in the contract you signed.
Knowing which procedures fall into this category saves you the months of frustration of fighting a denial that was never going to be reversed — and lets you move directly to pricing the procedure on your own terms.
The exclusion list
1. Cosmetic surgery
Breast augmentation, rhinoplasty, facelifts, liposuction, tummy tucks, and BBL are categorically excluded unless they are reconstructive (post-mastectomy breast reconstruction, for example, is mandated by the Women's Health and Cancer Rights Act). The line between "cosmetic" and "reconstructive" is where insurers save the most money and patients experience the most frustration.
US cash-pay: $5,000 to $25,000 depending on procedure. Colombia: $2,500 to $10,000. Route: colombiacosmeticsurgery.com
2. Dental implants
Most medical insurance excludes dental implants entirely. Dental insurance technically covers them in some plans, but annual maximums ($1,000 to $2,500 per year) make coverage functionally useless for implant cases that run $4,000 to $6,500 per implant or $20,000 to $60,000 for full-arch replacement.
US cash-pay: $4,000 to $6,500 per implant; $20,000 to $30,000 per arch (All-on-4). Colombia: $800 to $1,600 per implant; $6,500 to $11,000 per arch. Route: colombiadentist.co / fullarchreplacement.com
3. LASIK and refractive eye surgery
Classified as elective by virtually all insurers. LASIK, PRK, ICL, and SMILE surgery are never covered. Vision insurance discount programs reduce the price by $100 to $500 — meaningful but not transformative against a $5,000+ bill.
US cash-pay: $4,000 to $6,000 (both eyes). Colombia: $1,000 to $1,800. Route: colombialasik.com
4. Weight loss surgery (in some states)
Only 23 states mandate coverage for bariatric surgery under certain conditions. In the remaining 27 states, insurers can exclude it entirely — and many do. Even in mandate states, the qualification criteria (BMI above 40, or above 35 with comorbidities, plus documented failure of supervised diet programs) create a 6-to-18-month approval process that many patients cannot complete.
US cash-pay: $16,000 to $25,000 (gastric sleeve). Colombia: $4,500 to $6,500. Route: colombiabariatric.co
5. IVF and fertility treatments
Only 21 states have some form of fertility treatment mandate, and the coverage varies wildly — some mandate only diagnosis coverage, not treatment. A single IVF cycle costs $12,000 to $20,000 in the US. Most couples need 2 to 3 cycles.
US cash-pay: $12,000 to $20,000 per cycle. Colombia: $4,000 to $7,000. Route: colombianivf.com
6. Porcelain veneers
Classified as cosmetic dental work. Even comprehensive dental plans exclude veneers entirely.
US cash-pay: $1,000 to $2,500 per tooth. Colombia: $250 to $500 per tooth. Route: colombiadentist.co
7. Hair transplants
Cosmetic exclusion. No insurer covers FUE or FUT hair restoration.
US cash-pay: $10,000 to $20,000. Colombia: $3,000 to $5,000. Route: colombiahairtransplant.co
8. Stem cell therapy (most applications)
Most stem cell applications are classified as investigational. Insurance covers stem cell transplants for specific cancers and blood disorders, but regenerative applications for joints, anti-aging, and neurological conditions are excluded.
US cash-pay: $5,000 to $25,000. Colombia: $3,000 to $12,000. Route: colombiastemcelltreatment.com
9. Varicose vein treatment (cosmetic classification)
Insurance covers varicose vein treatment when documented as medically necessary (causing pain, ulceration, or circulation problems). When classified as cosmetic — which happens frequently — it is excluded. The classification fight is common.
10. Gynecomastia surgery (male breast reduction)
Almost always classified as cosmetic despite the significant psychological impact. Coverage exceptions exist for documented hormonal conditions, but approval is rare.
11. Jaw surgery (when classified as cosmetic)
Orthognathic surgery for functional bite problems may be covered by medical insurance. When the primary indication is aesthetic, it is excluded. The functional-vs-cosmetic determination is frequently disputed.
12. Second opinions abroad
Insurance covers second opinions from in-network providers. It does not cover consultations with international surgeons, virtual or in-person. If you are exploring medical tourism as an alternative to a denied procedure, the consultation cost comes out of pocket.
The common thread
Every procedure on this list shares one characteristic: high demand, high cost, and no insurer incentive to cover it. The exclusions are not based on medical evidence — many of these procedures have strong clinical support for the conditions they treat. They are based on actuarial math: excluding them keeps premiums lower for the insurer's risk pool.
The practical implication: if your procedure is on this list, skip the appeal and go directly to pricing it as a cash-pay patient. You will save months and get to the same destination faster.

Talk to Someone →Frequently asked questions
Can I appeal an exclusion?
Exclusions are different from denials. A denial says the procedure is covered but not approved for your case. An exclusion says the procedure is not covered under any circumstances. Exclusions cannot be appealed through the standard process — they are contract terms. Your options are cash-pay, medical tourism, or changing to a plan that covers the procedure (during open enrollment).
Are exclusions the same across all insurance companies?
No. Exclusions vary by plan, not just by insurer. Two plans from the same company can have different exclusion lists. Check your Summary of Benefits and Coverage (SBC) document for your specific plan's exclusions.
What about employer self-funded plans?
Self-funded plans (common at large employers) are governed by ERISA, not state insurance mandates. This means state-level coverage mandates for bariatric surgery or fertility treatments may not apply to your employer's plan. Check with your HR benefits team.
