Biohacking with Your HSA: What's Eligible (and What Needs Paperwork)

I’ll be honest: I spent a solid year buying things I thought were health investments — an Oura Ring, magnesium supplements, a CGM trial — without ever asking whether any of it could go through my HSA. Turns out a meaningful chunk could have, with the right paperwork. Here’s what actually works and what doesn’t.

The fast answer

A surprising amount of biohacker gear is HSA-eligible — but most of it needs an LMN tied to a specific diagnosed condition. CGMs, wearables, recovery tools, certain supplements, specialty blood work. The line is medical necessity. The IRS under Publication 502 only covers expenses for the diagnosis, cure, mitigation, treatment, or prevention of disease. “Optimizing” alone won’t fly.

TL;DR: Biohacking with your HSA works for items that map to real conditions. “Longevity” alone won’t fly.

“Continuous glucose monitoring has expanded beyond diabetes management — growing evidence supports its use in identifying early metabolic dysfunction, including insulin resistance and pre-diabetes, before clinical thresholds are reached.” — Journal of Clinical Endocrinology & Metabolism, 2024.

Caeli Spectrum

🟢 Auto-eligible (no LMN needed)

FDA-cleared CGMs for diagnosed diabetes, blood pressure monitors, pulse oximeters, routine annual blood work

🟡 LMN unlocks these

Off-label CGMs (Stelo, Lingo) for insulin resistance, smart wearables (Oura, Whoop, Apple Watch), Theragun, specialty lab panels, infrared saunas — with a specific documented condition

⚫ Won’t qualify

NMN/NR/NAD+ supplements, cryotherapy spas, red light therapy without a diagnosed skin condition, biohacker memberships, longevity retreats

TL;DR: Mappable to a condition? LMN works. “Optimizing” alone? Skip.

If you want to understand your metabolism

Diabetes diagnosis: auto-eligible, no LMN. Pre-diabetes or insulin resistance concern: LMN-eligible, and increasingly common as a documented metabolic condition. The clinician needs to specify the concern — “curiosity about my glucose” doesn’t fly, but “insulin resistance risk with fasting glucose trending above normal” does.

Viome Full Body Intelligence Test — $399

$399

The metabolic deep-dive Caeli actually stocks. An at-home test that reads gut, cellular, and metabolic markers and turns them into food and supplement guidance — useful when your concern is metabolic health rather than a single glucose reading. It is eligible through an LSA (plan-based), so coverage depends on your employer’s lifestyle account.

A note on CGMs: continuous glucose monitors like Stelo and Lingo follow the same rule (an LMN tied to a documented metabolic concern such as pre-diabetes or insulin resistance), but they are not in Caeli’s shop yet. If a CGM is what you want, keep the LMN logic in mind and check back.

TL;DR: Metabolic testing (Viome) is stocked and LSA-eligible. CGMs follow LMN rules but aren’t in the Caeli shop yet.

If you want to track sleep, heart, or recovery

Sleep disorder, anxiety, atrial fibrillation, or cardiovascular condition + LMN = wearable covered. The specific diagnosis determines which device makes the strongest case. Full picks and the diagnosis map are in the smart wearables guide — short version below.

Oura Ring 4 — $349 • Best for: sleep, anxiety, cycle tracking

$349.00

Whoop 4.0 — $239 • Best for: recovery, strain, and sleep load

$239.00

Apple Watch SE 3 — $249 • Best for: afib, cardiovascular monitoring

$249.00

TL;DR: Sleep disorder, anxiety, afib, or cardio condition + LMN = wearable covered. “I want to track my recovery” = no.

If you want recovery tools

Theragun Prime+ — $329.99 • LMN for chronic pain or fibromyalgia

$329.99

Well-established LMN category. Most straightforward recovery tool to get covered — if you have documented chronic pain or post-injury history, this is a routine approval.

Therabody RecoveryTherm Knee — $449.99 • LMN for chronic pain or circulation

$449.99

Targeted heat, cold, and vibration for a specific joint — a strong LMN case for documented arthritis, post-surgical recovery, or circulation issues. (Compression boots like Normatec follow the same rules but aren’t in Caeli’s shop.) Saunas and cold plunges are stricter still — expect more administrator pushback and a very specific diagnosis. Full breakdown in the recovery tools guide.

TL;DR: Theragun and targeted heat/vibration are common approvals. Sauna and cold plunge much stricter. Real diagnosis required in both cases.

If you want supplements

Specific supplements for documented deficiencies = LMN-eligible. Vitamin D for diagnosed deficiency ($17), magnesium for a documented sleep disorder or RLS ($21.99), omega-3s for a cardiovascular condition ($37.50). NMN, NR, NAD+ for “longevity”: no — the IRS treats them as general wellness. Full supplement breakdown in the vitamins guide.

TL;DR: Vitamin D for deficiency yes. Magnesium for sleep disorder yes. NMN for “living to 120” no.

If you want deep health testing

ClarityX Max Rx — $499

$499

A pharmacogenomic test that shows how your body metabolizes medications — genuinely useful if a prescription never seems to work at a standard dose. It is HSA/FSA-eligible on its own, no LMN required, because it is a diagnostic test.

23andMe Health Service — $199

$199

The at-home genetic health test Caeli stocks, HSA/FSA-eligible for its health-service portion. Traditional biomarker panels like InsideTracker and Function Health follow the same medical-necessity logic — clinical justification is what makes them eligible — but they aren’t in Caeli’s shop today.

TL;DR: Genetic and pharmacogenomic tests (ClarityX, 23andMe) are HSA/FSA-eligible on their own. Curiosity-driven biomarker panels still need a clinical hook.

Caeli Pro-Tip: Caeli’s integrated telehealth knows which biohacker categories pass administrator review and which don’t — and will tell you before you pay for a consultation. Install Caeli and let real expertise tell you what’s actually covered.

Frequently asked questions

Is the Stelo or Lingo CGM HSA-eligible without a diabetes diagnosis?

Yes — with an LMN tied to insulin resistance, pre-diabetes, or a documented metabolic concern. If your fasting glucose, A1C, or fasting insulin shows pre-diabetic markers, a telehealth clinician can issue the LMN.

Can I use my HSA to buy NAD+ or NMN supplements?

Generally no. NAD+/NMN are marketed for “longevity,” which the IRS treats as general wellness, not medical necessity. No specific diagnosed condition currently maps cleanly to NMN in a way administrators accept.

Does my HSA cover an at-home health test like Viome or 23andMe?

The health-service portion of genetic and metabolic tests is generally HSA/FSA-eligible; Viome is covered through an LSA where your plan offers one. Pure “optimization” testing without any clinical framing is where administrators push back.

Is an infrared sauna LMN-eligible in 2026?

Sometimes — with a documented circulation, skin (psoriasis, eczema), or chronic pain condition. Plan administrators are stricter on saunas than on Theraguns. Have a defensible LMN from a specialist ready.

Can I expense my Oura Ring subscription with my HSA?

The Oura Ring itself is HSA-eligible with an LMN. The subscription is plan-dependent — some administrators treat it as part of the device’s value; others classify it as a separate service. Try, document, and appeal if rejected.

Bottom line

Biohacking with your HSA works — if the items map to real conditions. Wearables for sleep and cardio, recovery tools for documented pain, specific supplements for documented deficiencies, genetic and metabolic tests for real concerns. Anything sold as “longevity” without a condition tied to it generally won’t pass review.

Install Caeli — telehealth knows what categories work and flags the ones that don’t before you waste money on a rejected claim.

TL;DR: Map your biohacker stack to real diagnoses. Skip anything labeled “longevity” without a clinical hook.
