What Is a Letter of Medical Necessity?
An LMN is a formal document written by a licensed healthcare provider. It explains why a specific product or treatment is medically necessary for a patient's condition. Think of it as official confirmation from your doctor that a purchase serves a genuine health purpose—not just a lifestyle upgrade.
HSA and FSA administrators require this kind of documentation for products that aren't automatically considered medical expenses. A massage chair, for example, is typically treated as a general wellness product. An LMN changes that by tying the purchase to a specific diagnosis and treatment plan.
Who Can Write an LMN?
Several types of healthcare professionals can write one, including:
- Physicians and doctors
- Chiropractors
- Physical therapists
- Nurse practitioners
- Other licensed healthcare providers authorized to diagnose your condition
Why Would You Need an LMN for a Massage Chair?
Most massage chairs don't qualify as FSA Eligible Massage Chairs by default. Without documentation linking the purchase to a medical condition, your HSA or FSA administrator may reject the claim.
However, a wide range of conditions may support medical necessity for therapeutic massage, including:
- Chronic back or neck pain
- Sciatica
- Arthritis
- Muscle tension or spasms
- Injury recovery
- Poor circulation
When your provider documents one of these conditions, and explains how a massage chair supports your treatment, it gives your HSA or FSA administrator the evidence they need to approve the expense.
How To Get a Letter of Medical Necessity for a Massage Chair
Step 1: Schedule an Appointment With Your Healthcare Provider
Book an appointment and come prepared. Talk through your symptoms, how long you've been dealing with them, and how they affect your everyday life. The more specific you are, the easier it is for your provider to understand the scope of your condition.
Step 2: Ask Whether a Massage Chair Could Help
Bring up massage therapy as a potential treatment option. Ask whether it aligns with your current care plan or long-term management strategy. Your provider may already recommend it, or may be open to it once you've discussed your needs.
Step 3: Request the Letter
Ask your provider to write a Letter of Medical Necessity. The form has all of the questions needed, but a complete letter should at least include:
- Your diagnosis
- The recommended treatment (in this case, massage therapy via a chair)
- A clear explanation of why a massage chair is medically necessary
- Your provider's signature, credentials, and date of issuance
Step 4: Save Everything
Keep a copy of your LMN along with any receipts and purchase records. Your HSA or FSA administrator may ask for documentation at any point, so having everything organized saves you a headache later.
Using Your HSA or FSA Funds To Buy a Massage Chair
Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs) both allow you to use pre-tax dollars for qualified medical expenses. This can significantly reduce the out-of-pocket cost of a massage chair—making it more affordable without compromising on quality.
To use your funds smoothly, obtain your LMN before making a purchase whenever possible. Then confirm the specific requirements with your HSA or FSA plan administrator, as policies can vary. Once you have the green light, you're ready to shop.
