💡 Quick Answer: WHOOP is HSA/FSA eligible because it helps prevent, manage, and reverse a variety of health conditions including cardiovascular disease, sleep disorders, and chronic fatigue, and many others. According to IRS Publication 502, you need a Letter of Medical Necessity in order for it to be eligible. Crates Health gets you approved in minutes and handles your reimbursement with one click.
What is Whoop
WHOOP is the screenless fitness tracker that turns recovery into a science and makes you obsessed with your own data. Unlike traditional fitness trackers with screens and notifications, WHOOP focuses purely on three critical metrics: Strain, Recovery, and Sleep.
The device itself is a lightweight strap (just 0.64 ounces) that tracks your heart rate 24/7 using photoplethysmography (PPG) technology, measures how hard you’re working your body, and tells you exactly how recovered you are each morning. With professional athletes, Navy SEALs, and weekend warriors as devoted users, WHOOP has become the gold standard for recovery-focused fitness tracking.
WHOOP’s Three Core Metrics:
- Strain measures how hard you push your body on a 0-21 scale based on cardiovascular load. The higher your heart rate and the longer you maintain it, the higher your strain score climbs.
- Recovery tells you how ready you are to perform, shown in simple green (optimal), yellow (adequate), or red (low) status. This is calculated using heart rate variability (HRV), a proven biomarker for stress, recovery, and autonomic nervous system function.
- Sleep provides detailed tracking of all four sleep stages (light, deep, REM, and awake), sleep efficiency, respiratory rate, and sleep debt. The National Sleep Foundation recognizes comprehensive sleep tracking as valuable for identifying and managing sleep disorders.
The magic happens when these metrics work together. WHOOP learns your patterns and tells you whether to push harder or rest up based on your HRV, sleep quality, and previous day’s strain. It’s like having a personal performance coach on your wrist who never sleeps.
Why Whoop Qualifies for HSA/FSA
According to IRS regulations, fitness trackers can qualify as eligible medical expenses with a Letter of Medical Necessity when used to prevent, monitor, or manage specific health conditions outlined in Publication 502.
IRS Publication 502 states that medical expenses are “the costs of diagnosis, cure, mitigation, treatment, or prevention of disease, and for the purpose of affecting any part or function of the body,” but “must be primarily to alleviate or prevent a physical or mental condition or illness.”
This means WHOOP can qualify for HSA/FSA reimbursement when used as a monitoring tool for prevention or treatment of specific medical conditions.
Medical Conditions That Qualify
WHOOP’s continuous health monitoring can support prevention or treatment plans for:
Cardiovascular Conditions
- Hypertension (high blood pressure)
- Arrhythmias and irregular heart rhythms
- Post-cardiac event recovery
- Cardiovascular disease risk management
Research in the Journal of Cardiopulmonary Rehabilitation and Prevention demonstrates that continuous heart rate monitoring improves outcomes for cardiac rehabilitation patients.
Sleep Disorders
- Insomnia
- Sleep apnea monitoring
- Circadian rhythm disorders
- Sleep quality optimization for chronic conditions
Mental Health Conditions
- Anxiety disorders
- Depression
- PTSD
- Chronic stress management
Studies published in JAMA Psychiatry show that HRV tracking can help monitor and manage anxiety and depression severity.
Metabolic Disorders
- Diabetes (Type 1 and Type 2)
- Pre-diabetes
- Metabolic syndrome
- Obesity management
Performance-Related Conditions
- Chronic fatigue syndrome
- ADHD and attention disorders
- Fibromyalgia
- Post-concussion recovery
The key requirement is that a healthcare provider must document the continuous health monitoring as medically necessary for preventing or managing your specific health condition. This documentation comes in the form of a Letter of Medical Necessity (LMN)
How to Assess Your Eligibility
Traditional Route: Schedule an appointment with your primary care physician, discuss your health conditions and fitness goals, and request a Letter of Medical Necessity if continuous health monitoring is recommended as part of your treatment plan. This typically requires an office visit, potential wait times, and can cost $50-100+ depending on your insurance.

Our platform connects you with licensed healthcare providers who can evaluate your conditions remotely and issue the appropriate documentation if you qualify. No office visits, no waiting weeks for appointments, and no surprise medical bills.
Frequently Asked Questions
Do I need a new Letter of Medical Necessity every year?
Most Letters of Medical Necessity remain valid for 12 months from the date of issue. Since WHOOP is a subscription service, you’ll want to renew your LMN annually to continue receiving HSA/FSA reimbursement. Crates Health makes renewals simple with automatic reminders and streamlined reprocessing.
Can I use my HSA/FSA for WHOOP accessories and bands?
Replacement bands, battery packs, and accessories typically do not qualify for HSA/FSA reimbursement on their own because they’re considered general wellness items. However, if you’re purchasing them as necessary replacements to continue medically necessary monitoring, you may be able to include them as part of your overall medical expense documentation. Consult with your HSA/FSA administrator for specific guidance.
Will WHOOP accept my HSA/FSA card directly?
WHOOP may directly accept HSA/FSA cards at checkout. If not, you’ll need to purchase your membership with a personal credit or debit card, then submit for reimbursement from your HSA/FSA account. This is where Crates Health simplifies the process. We handle the entire reimbursement workflow for you with one-click submissions directly to your HSA/FSA administrator.
What documentation do I need to save for reimbursement?
You’ll need two key documents:
Letter of Medical Necessity from a licensed healthcare provider
Itemized receipt from WHOOP showing the purchase date, item description, and amount paid
With Crates Health, we store all of this documentation for you and handle submissions automatically, so you don’t need to worry about organizing paperwork or dealing with clunky HSA/FSA portals.
Can I get reimbursed for WHOOP if I already purchased it?
No. You must have an LMN issued before the purchase date in order for it to be eligible. That said, so long as you have your LMN before your next purchase, you will be eligible to use HSA/FSA funds
What happens if my HSA/FSA administrator denies my claim?
Claim denials typically occur due to:
Missing or incomplete documentation (no LMN or non-itemized receipt)
Incorrect LMN format (administrator-specific requirements)
Timing issues (FSA funds expired or claim submitted outside the allowable window)
When you use Crates Health, we handle these issues proactively. If your claim is initially denied, we’ll work with you to identify the problem, provide additional documentation, and resubmit on
