Will my insurance reimburse an ADHD diagnosis letter fee?

Standard extended health benefits usually exclude document fees

Extended health plans reimburse listed health services, and a letter is not one of them. Plan booklets commonly carry an exclusion for charges for the completion of forms, reports or medical certificates, alongside exclusions for missed appointments and administrative fees. The reasoning is that the document is not treatment. So when you send a $49 letter receipt through the same claims portal as a therapy session, expect it to be declined unless your booklet says otherwise.

A few group plans do allow document fees, sometimes under a general medical services line and sometimes up to a small annual amount, so it costs nothing to check. Ask the plan administrator two questions: whether fees for medical letters or reports are an eligible expense, and whether the answer changes if the letter was written by a nurse practitioner rather than a physician. Write down the answer and the date; plan wording is what governs, not a phone summary.

A health spending account is the likelier route, because the CRA treats form completion as ancillary to medical care

Health spending accounts reimburse expenses that qualify under the medical expense tax credit, and the CRA's technical folio on that credit addresses documents directly. Paragraph 1.26 of Income Tax Folio S1-F1-C1 states that the completion of health and disability forms by a medical practitioner is considered ancillary to the provision of medical services, and that the associated costs may be claimed as an eligible medical expense. A diagnosis letter or report prepared by the practitioner who assessed you fits that description.

• The practitioner must be authorized in the province where the service was rendered. Nurse practitioners and psychologists are on the CRA's list for every province Finding Focus serves.
• The receipt should show the patient's name, the date, a description such as diagnosis letter or healthcare-provider report, the fee, and the practitioner's designation and registration number.
• Administrators apply the CRA rules with their own judgment, so if a claim is declined, ask which rule was applied and cite paragraph 1.26 when you appeal.

A wellness or personal spending account is different: it follows the employer's own list of eligible items and is a taxable benefit, so whether a letter fee qualifies depends entirely on that list. The distinction is explained at Can I use an employer wellness account for ADHD assessment fees?.

Provincial health plans do not insure letters, reports or certificates

No provincial plan pays for the document, whoever writes it. Newfoundland and Labrador's Medical Care Plan page, for example, lists the preparation of records, reports or certificates among the services it does not cover, and Ontario's description of what OHIP covers is limited to medically necessary physician and hospital services. This is why a family doctor charges for a sick note or an accommodation letter even when the visit itself was insured, and why provincial medical associations publish suggested fees for uninsured services such as forms and letters.

When the insurer asked for the letter, the insurer may pay for it

A document requested by an insurer for its own purposes is treated differently from one you order for yourself. Disability, critical illness and life insurers often use their own forms, such as an attending practitioner's statement, and many pay the practitioner's fee for completing that form directly or reimburse it up to a stated amount. If a claims examiner asks you for medical evidence of your ADHD, ask in the same conversation whether the insurer covers the cost of obtaining it and whether it wants its own form completed rather than a general letter.

Be aware of the other direction too. A letter you submit to a disability or life insurer becomes part of your file and can be relevant to underwriting. How a diagnosis interacts with those products is addressed at Does an ADHD diagnosis affect life insurance in Canada? and, for licensing questions, at Does an ADHD diagnosis affect my driver's licence or insurance?.

Ask which document the requester needs before paying for either

Paying for the right document once is cheaper than paying for the wrong one and then the right one. Finding Focus offers two after an assessment, and they serve different purposes.

Ask the employer, school or insurer what they need to see: a confirmation of diagnosis, a description of functional impact, or specific recommendations. A letter is enough for many purposes; a report is for readers who will act on the clinical detail. If a body has its own form, such as the CRA's Form T2201 for the disability tax credit, the form itself is the document, and the fee for completing it is treated as ancillary to medical services in the same way.

An unreimbursed letter fee can go on your tax return

Whatever no plan pays, keep for your federal medical expense claim. The fee is treated as ancillary to the medical service, the practitioner is authorized, and the receipt shows who was paid, which is what the CRA needs. The credit applies to your total eligible expenses above the lesser of 3% of net income or $2,834 for the 2025 tax year, so a $49 letter matters only in combination with your other medical costs for the same 12-month period, but there is no reason to leave it out of the file.
