Can I Use My HSA for Dental Work in Tijuana?

IRS Publication 502 allows medical and dental expenses incurred outside the United States, as long as the treatment is legal in the country where it's received and would qualify if performed in the U.S. There is no rule limiting HSA or FSA use to U.S. providers. Mexico is explicitly included.

Dental implants, abutments, and crowns; extractions and oral surgery; bone grafts and sinus lifts; root canals; fillings; periodontal treatment; bridges and dentures; and orthodontics including Invisalign and braces. All-on-Four and All-on-Six full-arch restorations qualify as restorative care.

Purely cosmetic procedures — teeth whitening, cosmetic veneers placed on healthy teeth, and 'smile design' work with no functional purpose. Veneers placed for structural or restorative reasons (e.g., fractured or worn teeth) usually do qualify; ask your dentist to document the medical necessity.

An itemized receipt in English (or with English translation) showing the procedure, date, and amount paid; the dentist's name, license number, and clinic address; and a brief diagnosis or treatment summary. Border Care Dental's partner clinics issue HSA-compatible receipts as standard.

You can pay the Tijuana clinic with your HSA debit card if it accepts international cards (many do), pay out of pocket and reimburse yourself from your HSA, or use an HSA-issued check. Reimbursing yourself is the most common approach and gives you the cleanest paper trail.

FSA funds work the same way but typically must be used within the plan year (with limited carryover). If you have a large FSA balance and a planned Tijuana procedure, time your treatment to land in the right plan year.
