Are Smart Rings & Apple Watch HSA/FSA Eligible? Complete Guide (2026)

Short answer: Smart rings and Apple Watch are not automatically HSA/FSA eligible. But with a Letter of Medical Necessity (LMN) from your doctor, many health-focused wearables can qualify — especially if you have a diagnosed condition the device helps monitor.

The key question isn’t “is this device eligible?” It’s “can my doctor justify it as medically necessary?”

HSA vs FSA: Quick refresher

Both accounts follow IRS Publication 502 for eligible medical expenses. General health/fitness devices don’t qualify. Devices prescribed to monitor or treat a specific medical condition can.

The Letter of Medical Necessity (LMN)

This is the document that makes or breaks your claim. A valid LMN must:

1. Name your diagnosed condition (e.g., sleep apnea, atrial fibrillation, hypertension, anxiety disorder)
2. State why the device is medically necessary for monitoring that condition
3. Specify the device and its relevant health features
4. Be signed by your doctor (MD, DO, NP, or PA)

Example conditions that support wearable claims:

• Sleep apnea → SpO2 monitoring, breathing rate tracking
• Atrial fibrillation → continuous heart rate, ECG (Apple Watch)
• Hypertension → blood pressure trend monitoring
• Anxiety/stress disorders → HRV monitoring
• Diabetes management → activity and sleep quality tracking

Device-by-device eligibility breakdown

Apple Watch (Series 9/10, Ultra 2)

HSA/FSA case strength: Moderate to Strong

Apple Watch has the strongest case among consumer wearables because of FDA-cleared features:

• ECG app (FDA-cleared for AFib detection)
• Blood oxygen monitoring
• Fall detection
• High/low heart rate notifications

Best conditions for approval: atrial fibrillation, fall risk (elderly), heart conditions requiring continuous monitoring.

Price: $399–$799 depending on model

RingConn Gen 3

HSA/FSA case strength: Moderate

RingConn Gen 3 monitors SpO2, heart rate, HRV, breathing rate, and blood pressure trends — a comprehensive sensor suite relevant to multiple conditions.

• Overnight blood pressure trend monitoring (unique among rings)
• Continuous SpO2 tracking
• Breathing rate measurement
• No subscription (stronger case: the device IS the medical tool, no ongoing software fee)

Best conditions for approval: hypertension monitoring, sleep apnea screening, stress/anxiety disorders.

Price: $349 (one-time, no subscription)

Oura Ring 5

HSA/FSA case strength: Moderate

Oura tracks SpO2, HRV, skin temperature, and has research partnerships with medical institutions.

• FDA pathway in progress for several features
• SpO2 and temperature monitoring
• Research-backed sleep analysis

Weakness for HSA claims: The $6/month subscription complicates things — is the subscription also covered? Most plan administrators say no.

Price: $399 + $72/year subscription

Samsung Galaxy Ring

HSA/FSA case strength: Weak to Moderate

Samsung Galaxy Ring offers heart rate, SpO2, and skin temperature but positions itself more as a fitness device than a health monitor.

Price: $399

Eligibility comparison table

How to submit an HSA/FSA claim for a wearable

Step 1: Get diagnosed. You need an existing medical condition. “I want to track my health” won’t work. “My doctor diagnosed mild sleep apnea and recommended continuous SpO2 monitoring” will.

Step 2: Ask your doctor for an LMN. Bring the device specs. Explain what health metrics it tracks and how they relate to your condition.

Step 3: Purchase the device. Pay with your HSA/FSA card if possible (simplest). Or pay out of pocket and submit for reimbursement.

Step 4: Submit the claim. Include:

• Receipt/proof of purchase
• Letter of Medical Necessity
• Device specification sheet showing health monitoring features

Step 5: If denied, appeal. First denials are common. Resubmit with additional documentation from your doctor explaining medical necessity.

Tips to increase approval chances

1. Buy the device for health monitoring, not fitness. Frame everything around your medical condition, not step counting or workout tracking.
2. Choose devices with more health sensors. More medical-grade features = stronger case.
3. Avoid bundles. Don’t buy a device with accessories that are clearly fitness-oriented (sport bands, gym cases). Buy the health monitoring device alone.
4. Time it right. If your FSA expires end of year and you have unspent funds, December is when most wearable HSA/FSA purchases happen.
5. No subscription is an advantage. Plan administrators are more likely to approve a one-time device purchase than an ongoing subscription.

Why “no subscription” matters for HSA/FSA

This is an underrated factor. HSA/FSA plan administrators prefer one-time purchases over recurring expenses. A $349 ring with lifetime access to health data is easier to approve than a $399 ring plus $72/year that might not be covered.

RingConn Gen 3 and Ultrahuman Ring Air both offer subscription-free models — the device purchase includes full access to all health data, forever. This makes the HSA/FSA paperwork simpler and approval more likely.

The bottom line

The wearable HSA/FSA space is evolving fast. As more devices get FDA clearances, approval rates will increase. For now, the combination of a clear medical diagnosis + Letter of Medical Necessity + a device with relevant health sensors is your best path to reimbursement.
