How medical financing typically works
Medical credit products (like CareCredit and similar programs) often offer a promotional 0% period, followed by deferred interest applied retroactively to the full original balance if it isn't paid off in time — typically in the 15–30% APR range once that window closes. This structure is common industry-wide; always read your specific card's terms, since they vary by issuer and promotion.
A simplified comparison
| Scenario | Procedure cost | Financing cost if not paid in promo window | Effective total |
|---|---|---|---|
| US, financed, paid off in time | $40,000 | $0 (0% promo honored) | $40,000 |
| US, financed, missed promo window | $40,000 | Deferred interest on full balance | Can exceed $50,000+ |
| Colombia, self-pay, no financing needed | $12,000–$25,000 | n/a | $12,000–$25,000 + travel |
Even accounting for flights and lodging, the self-pay-abroad total in this simplified example remains well below the domestic financed total — and carries none of the deferred-interest risk.
When financing domestically still makes sense
If continuity of care outweighs cost for your specific situation (see our decision framework on medicaltourismabroad.com's Briefing), or if you can reliably pay off a 0% promotional balance in full within the window, domestic financing can be the lower-risk choice despite the higher sticker price.

The Takeaway
Run the real math on your specific card's terms before assuming financing domestically is cheaper — a missed promotional deadline can flip the comparison entirely.
