A claim for custom orthotics is rarely refused because the device was unnecessary. It usually comes back for clerical reasons: a missing registration number, a receipt that calls the device an arch support, an assessment dated after the casting, or a plan that expected to review the file before the lab started work.

Whether your plan covers orthotic therapy at all is a different question, and our guide to extended health benefits in Ontario handles eligibility and limits. This is about the administration. Which documents matter, what order things have to happen in, and where claims stall.

What the file has to show

Two things, really. That a regulated clinician assessed your feet and concluded a prescription device was appropriate, and that the device was fabricated for your feet rather than bought off a shelf. Almost everything an insurer asks for traces back to one of those two points.

That is also why the paperwork follows the clinical work instead of running alongside it. A biomechanical assessment produces findings. The findings justify the device. The device is then made, fitted and paid for. A claim that arrives with those steps out of sequence tends to get questioned even when the care was entirely appropriate. If you are still at the stage of deciding whether any of this applies to you, the decision guide and the overview of custom orthotics are the better place to start.

The documents most Ontario plans ask for

Requirements differ between insurers, and between two employers who bought the same insurer's product. This is the common set:

• A prescription or referral note, where the plan requires one. Some plans accept a chiropodist's own prescription. Others want a physician or nurse practitioner to have written it, and a few want it dated before the assessment took place.

• The biomechanical assessment report, naming the diagnosis and the findings that support a custom device rather than a retail product.

• A description of the device and how it was made, including the casting or scanning method and the materials. The words "custom made foot orthotic" plus a stated fabrication method are worth more to an adjudicator than a product name.

• The lab invoice or a statement of fabrication. Some plans want it with the claim. Others ask only when a file gets pulled for review.

• A paid in full receipt showing the clinic address, the treating clinician's name and their registration number with the College of Chiropodists of Ontario.

Ask for all of it at the fitting appointment rather than months afterward. Assembling a file is easier while the visit is recent.

Ask before you pay: predetermination

A predetermination is a written opinion from your insurer, requested before money changes hands. Here is the assessment, here is the proposed device, here is the cost, what would you reimburse? Plans give it different names. Preauthorization and estimate both turn up.

It earns its paperwork when the amount is significant, when you changed jobs or plans in the past year, when a previous claim came back reduced, or when two plans are involved. One caution: the answer is an opinion based on what you submitted, not a promise, and it can shift if the device or the clinical picture changes. Even so, it removes most of the guesswork before you are out of pocket.

Why claims come back

• The device is described in retail language. Insole, insert and arch support all read as a drugstore purchase to someone adjudicating a file. The clinical distinction is real and belongs on the receipt; custom orthotics versus store bought insoles sets it out.

• The registration number is missing. Plans verify the provider before they pay.

• The dates run backwards. An assessment dated after the casting, or a prescription dated after the device was already made.

• The frequency limit has not reset. Many plans fund one pair per defined period, counted from the date of the last paid claim rather than from the start of the benefit year.

• The claim went into the wrong bucket. A health spending account and extended health benefits are adjudicated separately, and submitting to the account first can forfeit the extended health portion.

• Coordination order. With two plans, your own goes first, and the second plan needs the first one's explanation of benefits before it will look at the balance.

• No diagnosis anywhere in the file. A receipt on its own, with no clinical reason attached, is the most common version of an incomplete claim.

Two plans in one household

Adults normally submit to their own plan first and a spouse's plan second. For a child covered twice, the usual convention sends the claim to the parent whose birthday falls earlier in the calendar year, by month and day rather than by age. Both are industry conventions rather than law, so confirm them with the plans involved before relying on them. Build in waiting time: the second submission needs the first plan's explanation of benefits attached.

Dates worth putting in your calendar

Assessment to fitting is usually a few weeks, most of which is fabrication time at the lab. Reimbursement after that depends on the insurer and on whether the file was complete when it arrived. Electronic submission moves faster than paper.

Two resets matter, and they are often not the same date: when your benefit year restarts, and when your orthotics frequency limit restarts. If your current pair is wearing out, the refit or replacement guide explains how to tell which one you need, and the distinction can matter to the claim, because a refit and a new device are not always funded the same way. The same question comes up with a second pair prescribed for a specific sport, which some plans treat as a separate claim and others count against the same limit.

When a claim is denied

Ask for the reason in writing. A denial code by itself gives you nothing to act on.

Plenty of denials turn out to be resolved by sending a document that was never clearly requested in the first place, which is a reconsideration rather than an appeal, and it is usually quick. If the stated reason is clinical, your clinician can write a letter answering it directly and citing the assessment findings. If the reason is administrative, correct the document and resubmit. Should the plan hold its position, ask for the formal appeal process in writing along with the deadline that applies to you. Keep dated copies of everything you send.

What a clinic can and cannot do

We can give you a complete and accurate file: assessment findings, the diagnosis, the device description with its fabrication method, the lab documentation, and a receipt carrying the details plans verify. We can write a clarifying letter when a plan raises a clinical question, and we can submit electronically where your plan allows it.

What no clinic can do is decide what your plan pays. That sits between you, your employer's benefit design and the insurer, and anyone promising you an approval is describing something they do not control. Claims for other foot care run into the same documentation questions, which is why nail treatment coverage raises a similar list. If you have not been assessed yet, a chiropody foot assessment is the starting point, and the custom foot orthotics page explains what the device itself involves.

Frequently Asked Questions

Is a doctor's note required before an orthotics claim will be processed?

It depends on the plan. Some accept a chiropodist's prescription, some require a physician or nurse practitioner, and some ask for nothing beyond the assessment report. Call the number on your benefits card and ask specifically whether a referral is a condition of reimbursement, because that wording gets you a clearer answer than asking whether orthotics are covered.

Can I get something in writing from my insurer before I commit?

Yes, and it is worth doing. Request a predetermination, which your plan may call a preauthorization or an estimate. Send the assessment report, the proposed device description and the cost. What comes back tells you what the plan would reimburse based on what you sent.

My plan paid for a pair last year. When can I claim again?

Usually after a set period measured from the date of the last paid claim, not from January and not from your renewal date. Ask the insurer for the exact next eligible date rather than the length of the interval. The two are easy to mix up and only one of them is useful.

The receipt says foot orthoses. Is that going to be a problem?

No. Foot orthosis and orthotic are both standard clinical terms. What matters is that the receipt also records that the device was custom fabricated and by what method. Wording such as insert or arch support, with no fabrication detail, is what invites a reduced payment.

Nothing has happened in six weeks. Who should I be chasing?

The insurer, with your claim number, asking whether anything on the file is outstanding. A clinic can resend a document quickly once you know which one is missing, but we have no view into the status of your claim.

Does a second pair for sport need its own paperwork?

Plan on it. A second device is generally justified by its own clinical reasoning, for example a different shoe volume or a different load through the foot, and that reasoning belongs in the file. Whether the plan will fund two pairs inside one period is a coverage question to put to the insurer first.

Book an assessment

None of the paperwork matters until someone has actually looked at your feet. To get an assessment and a clear account of whether a prescription device is appropriate for you, book an appointment online at Donwood Foot Clinic in North York, or call the clinic. Ask at that visit which documents your particular plan will want, and you can assemble them as you go.
