LETTER OF MEDICAL NECESSITY TEMPLATE FAQ
What is a letter of medical necessity?
A letter of medical necessity is a written statement from a licensed medical provider explaining that a treatment, service, product, or expense is medically necessary for a patient’s diagnosis, treatment, or care. It is often used to support insurance requests, reimbursement claims, or approval of certain FSA, HSA, or HRA expenses. The IRS treats medical care as expenses for the diagnosis, cure, mitigation, treatment, or prevention of disease, and FSAFEDS states that some potentially eligible expenses require this kind of provider documentation.
Why do you need a letter of medical necessity?
You need a letter of medical necessity when a payer, plan administrator, or benefits program wants proof that the requested item or service is medically necessary rather than mainly helpful for general health, comfort, or personal preference. FSAFEDS specifically says some expenses require a Letter of Medical Necessity, and it notes that a provider letter can work if it includes the needed information.
When should you use a letter of medical necessity?
Use a letter of medical necessity when you are requesting coverage, reimbursement, or approval for a treatment, supply, service, or dual-purpose expense that may need added medical justification. FSAFEDS says this is commonly needed for certain “Maybe Expense” items and for expenses listed as requiring a letter, and it also notes that a new letter may be needed if the treatment period extends beyond the prior approval period.
How to write a letter of medical necessity?
Start with the provider’s information, the patient’s information, and the specific diagnosis or medical condition. Then explain the recommended treatment, item, or service, why it is medically necessary, how long it is expected to be needed, and any limits or clinical details that support the request. FSAFEDS says a sufficient provider letter should include the medical condition, recommended treatment, duration of treatment, and the licensed practitioner’s name and signature, and if the treatment could appear cosmetic, it should state that it is not cosmetic in nature.
