FSA Eligible Wellness Expenses: What's Covered in 2026

A complete guide to FSA-eligible wellness expenses in 2026. Learn what your Flexible Spending Account covers — from gym memberships to supplements — and how LMNs expand your options.

FSAWellnessEligible Expenses2026
Your FSA covers more wellness expenses than you probably think — especially when you have a Letter of Medical Necessity (LMN). In 2026, the FSA contribution limit is $3,300, and with the right documentation, that money can go toward gym memberships, supplements, massage, mental health apps, and much more.

FSA Basics: A Quick Refresher

A Flexible Spending Account lets you set aside pre-tax dollars for qualified medical expenses. The key rules in 2026:

  • Contribution limit: $3,300/year (up from $3,200 in 2025)
  • Use-it-or-lose-it: Funds generally expire at year-end, though your employer may offer a grace period (up to 2.5 months) or carryover (up to $640)
  • Employer-sponsored: FSAs are offered through your employer's benefits plan
  • No investment: Unlike HSAs, FSA funds can't be invested or carried forward indefinitely

The "use it or lose it" rule is exactly why knowing your eligible expenses matters. Don't leave money on the table.

What's Automatically FSA-Eligible (No LMN Needed)

These expenses are qualified medical expenses by default:

Medical Care

  • Doctor copays and deductibles
  • Prescription medications
  • Dental care (cleanings, fillings, orthodontics)
  • Vision care (eye exams, glasses, contacts)
  • Mental health therapy (licensed providers)
  • Physical therapy
  • Chiropractic care
  • Acupuncture

Over-the-Counter Items (Since 2020)

  • Pain relievers (Advil, Tylenol)
  • Allergy medications (Claritin, Zyrtec)
  • Antacids and digestive aids
  • First aid supplies
  • Sunscreen (SPF 15+)
  • Menstrual products
  • Reading glasses

Medical Equipment

  • Blood pressure monitors
  • Thermometers
  • CPAP machines and supplies
  • Hearing aids and batteries
  • Glucose monitors (prescribed)
  • Bandages and wound care

Wellness Expenses That Become FSA-Eligible With an LMN

This is where it gets interesting. With a Letter of Medical Necessity from a licensed provider, these wellness expenses can qualify:

Fitness and Exercise

  • Gym memberships — for obesity, diabetes, cardiovascular disease, depression
  • Fitness equipment (Peloton, treadmill, weights) — for prescribed exercise programs
  • Personal training — when part of a medical treatment plan
  • Yoga and Pilates classes — for chronic pain, anxiety, rehabilitation
  • Fitness apps (Peloton app, Apple Fitness+) — for prescribed exercise programs

Supplements and Nutrition

  • Vitamins and supplements — for diagnosed deficiencies or conditions
  • Protein powder — for malnutrition, muscle wasting, post-surgical recovery
  • Probiotics — for diagnosed digestive conditions
  • Fish oil/Omega-3 — for cardiovascular conditions
  • Meal delivery services — for specific dietary medical needs

Wellness Services

  • Massage therapy — for chronic pain, injury recovery, stress-related conditions
  • Meditation apps (Headspace, Calm) — for anxiety, insomnia
  • Sleep products (weighted blankets, white noise machines) — for sleep disorders
  • Ergonomic equipment (standing desks, chairs) — for musculoskeletal conditions

Health Monitoring

  • Wearable devices (Whoop, Oura, Apple Watch) — for cardiovascular or sleep monitoring
  • Consumer CGMs — for prediabetes or metabolic health
  • Health coaching — when provided by or prescribed by a licensed provider

How to Get an LMN for FSA Expenses

The process is identical to HSA LMNs:

  • Have a diagnosed medical condition that the expense addresses
  • Get a letter from a licensed provider stating the expense is medically necessary
  • Submit the LMN to your FSA administrator if requested
  • Pay with your FSA card and keep receipts

    • The LMN should include your diagnosis, the specific expense, how it treats your condition, and your provider's credentials.

    FSA Spending Strategy: Don't Lose Your Money

    Since FSA funds expire, having a strategy matters:

    Early in the Year (January–March)

    • Use funds for known recurring expenses (prescriptions, therapy, contacts)
    • Get LMNs for planned wellness purchases

    Mid-Year (April–August)

    • Check your balance and spending pace
    • Schedule elective procedures (dental work, vision exams)
    • Purchase fitness equipment or gym memberships with LMNs

    End of Year (September–December)

    • Calculate remaining balance
    • Stock up on OTC items (sunscreen, first aid, allergy meds)
    • Make larger wellness purchases (standing desk, weighted blanket, supplements)
    • Schedule any remaining appointments

    The "Oh No, I Have Money Left" Emergency Kit

    If it's December and you still have FSA funds, here are quick eligible purchases:

    • Prescription sunglasses or backup glasses
    • Year's supply of contact lenses
    • OTC medicine cabinet restock
    • First aid kit refresh
    • Sunscreen stockpile
    • With an LMN: supplements, ergonomic equipment, sleep products

    FSA vs HSA: Which Is Better for Wellness?

    Feature FSA HSA
    Contribution limit (2026) $3,300 $4,400 (individual) / $8,750 (family)
    Funds expire? Yes (year-end) No (rolls over forever)
    Investment options No Yes
    Requires HDHP? No Yes
    LMN wellness expenses Yes Yes
    Portability Tied to employer Yours forever

    If you have access to an HSA, it's generally the better long-term vehicle. But if your employer offers an FSA and you don't have an HDHP, the FSA is still a powerful tool — especially for wellness expenses.

    FAQ

    Can I use my FSA for a gym membership in 2026?

    Yes, with a Letter of Medical Necessity. Your provider must document that a gym membership is medically necessary for a diagnosed condition like obesity, diabetes, or depression. Without an LMN, gym memberships aren't FSA-eligible.

    What happens to unused FSA money at the end of the year?

    It depends on your employer's plan. Options include: full forfeiture (use it or lose it), a grace period of up to 2.5 extra months to spend, or a carryover of up to $640 into the next year. Check with your HR department.

    Can I have both an FSA and an HSA?

    Generally no — a general-purpose FSA and an HSA aren't compatible. However, you can pair an HSA with a Limited Purpose FSA (LPFSA), which covers only dental and vision expenses.

    Do I need a separate LMN for each FSA expense?

    Not necessarily. A comprehensive LMN can cover multiple related expenses (e.g., gym membership, supplements, and massage all prescribed for obesity management). Work with your provider to include everything relevant.

    Is the FSA contribution limit per person or per family?

    The $3,300 limit is per person. If both spouses have employer-sponsored FSAs, each can contribute up to $3,300 — potentially $6,600 per household in pre-tax wellness spending.
