Why the default receipt isn't enough
Colombian clinics issue a factura — a legal invoice under the national electronic-invoicing system — and it's a real document. But it's designed for Colombian tax and accounting, so it may show the clinic's trade name rather than its legal name, a single line for "servicios de cirugía refractiva," an amount in pesos only, and your name as it appeared on a WhatsApp message. Each of those is a problem for one of the payers below. None of them is hard to fix, provided you ask at the coordinator stage rather than at your kitchen table three weeks later.
The rest of this article is not tax or insurance advice; it's what patients from the US, Canada, and the UK have told us their administrators wanted, and what we now ask clinics for by default. Check your own plan's rules.
What each payer typically asks for
Documentation by payer
What US, Canadian, and UK patients are commonly asked to produce for LASIK abroad
| Payer / scheme | Usually eligible? | What they tend to ask for |
|---|---|---|
| US HSA / FSA | LASIK is a qualified medical expense under IRS Publication 502. Foreign providers are not excluded. | An itemised receipt showing provider name, patient name, date of service, description of service, and amount. Many administrators want it in USD or with a conversion shown. Keep it with your tax records; you may not be asked for it until an audit. |
| US vision or health insurance | Usually not covered — LASIK is elective. Some vision plans offer a discount through their own network, which won't apply abroad. | If you submit anyway (for an out-of-network reimbursement benefit some plans have), the same itemised receipt plus a procedure description; a CPT-style code helps but isn't required. |
| Canada — Medical Expense Tax Credit | Laser eye surgery is on the CRA's eligible medical expense list; foreign providers qualify if the practitioner is licensed where they practise. | The itemised receipt with the clinic's name and address, your name, date, and amount; convert to CAD at the Bank of Canada rate for the date. Travel costs have their own rules and generally don't apply to elective surgery abroad. |
| Canada — private / employer benefits | Some plans include a laser eye surgery benefit or a health spending account. | Itemised receipt and often a claim form; a surgeon's letter describing the procedure and eyes treated helps. |
| UK — private health insurance | Rarely; most UK policies exclude refractive surgery. A few include an optical cash benefit. | Itemised receipt; if claiming a cash benefit, the surgeon's letter naming the procedure. |
| UK — HMRC | No general tax relief for medical treatment. | Nothing to claim; keep the receipt for your own records. |

The invoice we ask clinics for
Whichever payer you're dealing with, one document covers them all if it has the following on it. Ask for it when you confirm the balance, not after.
- The clinic's legal name, address, and tax ID (in Colombia, the NIT). If the clinic trades under a different brand name, both should appear.
- The operating surgeon's name and licence number. Some administrators want the "provider" to be an individual; the licence number is what makes a foreign provider verifiable.
- Your full legal name exactly as on your passport, and your passport number. Not a first name, not a nickname from the booking chat.
- Date of service for each line — exam date and surgery date are usually different days.
- The procedure named specifically and per eye: "Femtosecond LASIK, right eye" and "Femtosecond LASIK, left eye" as two lines, rather than "refractive surgery." If a Colombian procedure code (the CUPS system) is printed, leave it on; it doesn't hurt.
- Separate lines for the pre-op exam, the surgery, post-op medications and drops, and any enhancement policy or package component. Some HSA administrators query a single lump sum; itemised lines get approved.
- Amounts in COP — the legal currency of the invoice — with the USD (or CAD/GBP) equivalent and the exchange rate and date used. Clinics can add this as a note; it saves you arguing about conversions later.
- Payment method and a "paid in full" statement, with the card's last four digits or the transfer reference. If you paid a deposit earlier, the invoice should show it as a credit against the total.
- An English version, or at least English line descriptions alongside the Spanish. A summary translation from the clinic is usually enough; certified translation is rarely requested for these amounts.
Most clinics in the network produce this without fuss when asked at the right moment. The reason to ask before paying is that once the electronic invoice is issued, amending it is a bureaucratic process at the clinic's end, and a second "credit note" version can confuse an administrator more than the original did.
The documents to keep with it
An invoice on its own answers "how much." Payers sometimes also want "for what" and "was it real," and two documents you already have cover that.
- The signed consent form, which names the procedure and the eye(s). Details on getting your copy in the consent form article.
- The surgeon's post-op note or discharge letter, which confirms the procedure was performed and gives the follow-up schedule. You want this anyway for your home optometrist — see Setting up LASIK follow-up care at home.
Optional but useful: the pre-op exam report, which shows the clinical basis for the procedure. How to ask for it in a usable format is in translating your records.
Paying in a way that documents itself
How you pay affects the paper trail. A card payment produces a statement line with the merchant's name, which is the corroboration most administrators want. A bank transfer produces a transfer record. Cash produces only the clinic's receipt, which is legal and usually fine for an HSA but weaker if anyone ever queries it. The trade-offs on fees and exchange rates are in Deposit and payment for LASIK abroad; from a documentation standpoint, pay the deposit and the balance by a method that leaves a trail, and get the invoice to reflect both.
If you split payment across a deposit weeks earlier and a balance on the day, ask for a single final invoice showing the total, the deposit credited, and the balance paid, rather than two unrelated receipts. Administrators match one document to one claim.
Travel and accommodation
US rules allow some medical-travel transportation and limited lodging costs as medical expenses in specific circumstances; Canada's travel rules are designed around care not available locally and generally don't reach elective surgery abroad; the UK has no equivalent. We don't give tax advice and won't pretend to know your situation. What we can do is make sure the transfer and hotel receipts you receive through the desk are itemised and dated, so if your advisor tells you they're claimable, the paperwork exists.
Timing
For an HSA or FSA, the expense is typically claimable in the year you paid, at the exchange rate on the payment date; for FSAs specifically, check your plan year and grace period, because a December trip can straddle two. For the Canadian credit, the claim goes on your return for the year of the expense. In every case, the invoice with the date and the rate on it is what makes the claim simple.
If you booked through the desk, tell us which scheme you'll be claiming under and we'll send the clinic our invoice checklist before your surgery day. If you booked direct, copy the nine items above into one email to the coordinator. Either way, do it before the balance is paid.
What if the invoice you already have is wrong
Ask the clinic for a corrected or supplementary invoice — Colombian electronic invoicing allows a credit note and a re-issue, though it takes the clinic's accountant a few days. Failing that, a signed letter from the clinic on letterhead that provides the missing details (legal name, NIT, procedure per eye, USD conversion) alongside the original invoice satisfies most administrators. Keep every version together.
Questions we get at the desk
Can I use my HSA or FSA for LASIK in Colombia?
LASIK is a qualified medical expense under IRS Publication 502, and foreign providers aren't excluded. You'll need an itemised receipt with provider name, your name, date, description, and amount. Check your administrator's rules.
Does the invoice need to be in English?
Ask for English line descriptions alongside the Spanish. A summary translation from the clinic is usually enough; certified translations are rarely requested for these amounts.
What's a NIT and why do I need it on the invoice?
The clinic's Colombian tax ID. Administrators and tax authorities use it to verify the provider is a real registered business.
Can I claim flights and hotels for a LASIK trip?
Rules vary by country and are narrow. We're not tax advisors — ask yours — but keep itemised, dated receipts for everything so the option exists.
