Letter of Medical Necessity for Optum
Honest answer: Optum is the administrator where a gym LMN faces the most friction. Optum’s standard eligible-expense lists treat gym memberships as not qualified, and Optum publicly steers gym and wellness spending toward employer Lifestyle Spending Accounts instead. That does not make a letter worthless — but you should know the terrain before you buy anything.
What Optum requires
- Call Optum (or check your plan documents) BEFORE relying on reimbursement — plan designs vary
- If your plan does honor LMNs: the standard letter elements apply — diagnosis, named expense, duration, signature
- For an Optum Bank HSA specifically: IRS rules (IRC §213(d)), not Optum’s FSA list, govern what you can self-reimburse — keep bulletproof documentation
The steps, in order
- Check first: ask Optum or your HR team whether your specific plan reimburses medically necessary fitness expenses with an LMN
- If yes — letter first, pay out of pocket, submit with receipts
- If your employer offers a Lifestyle Spending Account, gym fees may simply belong there, no letter needed
- If you hold an Optum Bank HSA and a genuine qualifying diagnosis, a strong LMN supports self-reimbursement under IRS rules — with the documentation risk carried by you at audit

Ask Optum about your specific plan first. If the plan excludes gym expenses, a letter will not override it, and we would rather tell you that than sell you a letter your plan won’t honor.
HSAs follow IRS rules on qualified medical expenses rather than a claim-review list, and there is typically no upfront review. A letter grounded in a real diagnosis is your documentation if the IRS ever examines the withdrawal.
An employer-funded perk account for wellness spending — gym fees often qualify there with no medical documentation at all. If you have one, use it first.
