Best HSA-Eligible Continuous Glucose Monitors (2026)
Continuous glucose monitors (CGMs) now span prescription diabetes devices and over-the-counter wellness products. HSA eligibility depends on the medical purpose and the specific charge, not simply whether the sensor is sold without a prescription. Compare the device, app, coaching, and documentation separately before you buy.

The short answer
Start with medical purpose, then choose the device. For diagnosed diabetes, compare prescription coverage and clinician fit. For an over-the-counter experiment, compare the sensor price and avoid assuming the app or coaching bundle shares the device's eligibility.
Trying an OTC sensor
Lingo and Stelo publish direct consumer offers. Compare the current sensor cadence and intended-use label, then document the specific medical purpose if you plan to use HSA funds.
Adding analytics or coaching
Levels and Nutrisense add software, and each offers separately structured expert-support options. Decide whether those layers are worth paying for before considering tax treatment, and ask for an itemized breakdown.
Avoid this mistake: Do not choose a CGM because a checkout accepts an HSA card or because a seller calls it HSA/FSA eligible. Card acceptance, OTC status, and an LMN are evidence inputs, not reimbursement guarantees.
Compare the decision factors
Prices and checkout terms can change. Use this table to narrow the choice, then verify the current vendor or merchant page before paying.
| Option | Best for and tradeoff | Current published price | HSA and documentation note |
|---|---|---|---|
| Levels | Consider for: people who want a separate analytics membership and optional Stelo sensor delivery. | $15/mo or $80/yr membership; Stelo add-on $89/shipment or $99 one-time | Levels offers a software membership and optional Stelo sensors. Its support materials describe a Truemed evaluation path, but a membership, sensor, and coaching charge should not be assumed to share the same tax treatment. |
| Lingo | Consider for: a short, lower-cost over-the-counter glucose experiment with Abbott hardware. | $54 for the current 2-week plan | Lingo markets its current over-the-counter biosensor as HSA/FSA eligible. OTC availability does not by itself decide tax eligibility, and Lingo says the product is not intended to diagnose disease. |
| Stelo | Consider for: adults not using insulin who want Dexcom's over-the-counter sensor and its included app coach. | $89 monthly, $252 three-month, or $99 one-time | Stelo is sold without a prescription and says HSA/FSA funds can be used. Keep the device receipt and medical-purpose documentation appropriate to your facts. |
| Dexcom G7 | Consider for: people managing diabetes with a clinician and a prescription. | Coverage and cash price vary; Dexcom says most covered patients pay $20 or less | Dexcom G7 is a prescription device for diabetes management. Keep the prescription, itemized receipt, and insurance explanation of benefits when applicable. |
| Nutrisense | Consider for: people who specifically value dietitian support and will verify the current program terms. | CGM program from $179/mo before promotions; app-only $39/mo | Nutrisense combines sensors, software, and coaching. Verify current pricing and whether each charge supports your medical purpose before using HSA funds. |

Common Questions
Are CGMs HSA-eligible without diabetes?▼
Possibly, when the device is used to diagnose, treat, or monitor a specific medical condition and your documentation supports that purpose. General wellness or curiosity alone does not satisfy the IRS medical-care standard. Ask your administrator what evidence it requires.
How do I get an LMN for a CGM?▼
Ask the clinician treating the condition you plan to monitor. Some merchant flows also offer an evaluation, but an LMN does not make a general-wellness purchase automatically eligible and does not guarantee administrator approval.
Does my HSA cover the sensors and the app subscription?▼
Do not assume a bundle makes every charge eligible. A diagnostic device, software membership, and coaching service can have different medical purposes and documentation. Keep an itemized receipt and verify ambiguous membership or coaching charges with your administrator.
How do the CGM apps differ?▼
Levels sells a separate analytics membership with food logging and glucose-response insights. Lingo and Stelo include their own sensor apps. Nutrisense offers an app-only plan and CGM programs with optional dietitian support. Compare the workflow you will use rather than an unsupported quality ranking.
Can I use insurance for any of these consumer CGMs?▼
Coverage varies by plan and medical criteria. Dexcom G7 is a prescription diabetes product and may be covered; consumer wellness programs and over-the-counter sensors are commonly sold outside insurance. Check your plan before choosing on price.
How do I log a CGM subscription in HSA Trackr?▼
Record each charge under the actual seller and date. Attach the itemized receipt, proof of payment, prescription or LMN when applicable, and insurance explanation of benefits. Do not assume one document covers later charges without checking its dates and scope.
