Dexcom CGM can cost $0 to $89 per month for some commercially insured users, while people paying cash may face a much higher pharmacy price before applying a manufacturer coupon. Dexcom states that most patients with CGM coverage pay $20 or less per month. Exact costs depend on the Dexcom model, prescription, insurance plan, deductible, pharmacy or medical-equipment benefit, receiver needs, and savings-program eligibility.

Dexcom G7 and G7 15 Day use disposable all-in-one sensors, so there is no separate transmitter bill. Dexcom G6 uses 10-day sensors and a reusable transmitter lasting about three months, but Dexcom stopped manufacturing G6 on July 1, 2026 and is moving users toward G7 or G7 15 Day.

Stelo costs $99 for a one-month supply, $89 per month with recurring delivery, or $252 for a three-month subscription. Stelo is an over-the-counter biosensor for eligible adults who are not using insulin. It is not the cash subscription version of prescription Dexcom G7.

Dexcom’s current cost page says most people with CGM insurance coverage pay $20 or less each month. That figure describes covered users rather than a guaranteed price for every prescription.

Another Dexcom pricing page says eligible users may pay as little as $89 per month with commercial insurance. The amount at the pharmacy can change when the plan resets its deductible, moves the product between coverage tiers, requires prior authorization, or processes CGM through durable medical equipment rather than the pharmacy benefit.

People without CGM coverage should not use one uncited national cash average. Dexcom’s pharmacy program currently offers $210 or more off each 30-day sensor supply and more than $200 off a receiver. The final amount depends on the pharmacy’s starting price and the coupon’s current terms.

What Dexcom CGM Includes

A continuous glucose monitor uses a small wearable sensor to measure glucose in interstitial fluid. The system sends readings and trend information to a compatible smartphone, receiver, connected watch, or supported insulin-delivery device.

Prescription Dexcom products can display glucose readings, trend arrows, historical information, and alerts based on the product and user settings. They do not replace every meter check in every circumstance. Users should follow the product instructions and their clinician’s directions when readings do not match symptoms or expectations.

A compatible phone is not included in the sensor price. Dexcom maintains a current list of supported Apple and Android devices on its G7 compatibility page. A phone that can install the app is not necessarily an officially supported device.

Some users choose a dedicated receiver instead of a smartphone or use both. Dexcom states that G7 and G7 15 Day can operate with the app, the receiver, or both. Medicare users may need to use the receiver for coverage purposes.

Dexcom G7 Monthly Cost

Standard Dexcom G7 uses an all-in-one sensor designed for up to 10 days of wear, followed by a grace period. A continuous 30-day supply normally requires three sensors. There is no reusable transmitter to purchase every three months.

Insurance coverage can place the patient cost anywhere from $0 to a high deductible or coinsurance amount. Dexcom says most covered patients pay $20 (about 40 minutes at $30 per hour) or less per month, but this is not a universal copay.

Without CGM coverage, Dexcom’s savings program reduces the retail cash price of a monthly sensor pack by at least $210. Dexcom does not publish one final nationwide coupon price because retail pharmacy prices differ.

A patient whose pharmacy starts at a hypothetical $390 for a monthly sensor pack and applies a $210 discount would pay $180. If the starting cash price were $450, the same discount would produce $240. Those examples show why the advertised savings should not be mistaken for a fixed checkout price.

G7 15 Day Cost

Dexcom G7 15 Day received FDA clearance in April 2025 and entered broader U.S. availability later. Each sensor is designed for up to 15 days of wear, so a one-month supply uses two sensors rather than three standard G7 sensors.

Dexcom says most covered patients pay $20 or less per month and expects the patient copay for G7 15 Day to match standard G7 when the insurance plan covers both. Coverage can lag after a new product launches, so the pharmacy should run the exact prescription before the user switches.

The FDA clearance record identifies the G7 15 Day system as a separate product from standard G7. G7 15 Day is currently intended for adults aged 18 and older. Children and teenagers remain on standard G7 when prescribed a Dexcom system.

G7 15 Day may lower the number of sensor changes from about 36 standard 10-day sensors per year to roughly 24 sensors per year. That is 12 fewer insertion events, but it does not mean the patient’s copay automatically falls by one-third. Insurance commonly prices CGM by a monthly supply rather than by the number of sensor boxes.

ThePricer Annual Sensor Math

Standard G7 requires about three sensors per 30-day supply. Across twelve 30-day fills, that equals 36 sensors. G7 15 Day uses two sensors per 30-day supply, or 24 sensors across twelve fills.

ThePricer calculation: moving from 36 standard G7 sensors to 24 G7 15 Day sensors reduces annual sensor use by 12 units, equal to 33.3%. The percentage describes physical sensor count, not a promised reduction in copay or insurer spending.

A covered patient paying $20 per month spends $240 per year. A person paying the cited commercial-insurance floor of $89 per month spends $1,068 per year.

The difference between those two covered scenarios is $828 per year. Both can be legitimate Dexcom costs because plan design, deductible status, employer benefits, and coupon eligibility create different patient bills for the same device.

The Receiver Price Trap

A receiver is optional for many users with a compatible smartphone, but it can become necessary when the phone is unsupported, the user prefers a dedicated display, or insurance rules require receiver use.

Dexcom does not publish one simple retail receiver price on its main cost page. Its savings disclosures state that the current coupon provides more than $200 off a Dexcom receiver, based on a $240 discount spread across a one-year comparison.

This wording means $240 is the discount, not the receiver’s full retail price. The old article incorrectly presented receiver amounts from $0 to $899 as though they were a stable current range.

A patient using a compatible smartphone may have no separate display-device purchase. The phone itself, mobile data, replacement costs, and smartwatch are not included with the CGM prescription.

What Happened to Dexcom G6

Dexcom G6 uses a different supply structure. Each sensor lasts up to 10 days, while the reusable transmitter battery lasts about three months. A year of full-time use requires about 36 sensors and four transmitters.

Dexcom announced that G6 manufacturing would continue only through July 1, 2026. Remaining supplies may still appear at pharmacies and medical distributors, but continued availability is not guaranteed. Dexcom recommends moving to G7 or G7 15 Day through its G6 transition program.

The transmitter distinction matters when reading old cost estimates. A 2022 or 2023 G6 total may include separate transmitter purchases, while a current G7 budget does not. Combining the two product structures creates an inaccurate monthly price.

Users whose insulin pump or automated insulin-delivery system has limited sensor compatibility should verify the connected-device list before changing models. G7 15 Day compatibility was still being added across some pump systems during 2026.

Stelo Is a Separate Product

Stelo is an over-the-counter Dexcom glucose biosensor for adults aged 18 or older who do not use insulin. FDA’s original clearance excluded people with problematic hypoglycemia because the device is not designed to alert users to dangerous low glucose in the same manner as a prescription CGM intended for insulin treatment decisions.

Dexcom sells a one-month Stelo supply for $99. A recurring monthly order costs $89, while the three-month option costs $252. Shipping is included on the current Stelo purchase plans.

ThePricer calculation: the three-month subscription works out to $84 per month. Compared with twelve one-time purchases at $99, a full year of quarterly subscriptions costs $1,008 instead of $1,188, a difference of $180.

Stelo does not require a prescription, but it is not a substitute for G7 when a person needs prescription CGM features, insulin-pump integration, low-glucose alerts, or clinician-directed diabetes treatment. The separate Stelo cost guide covers its cash-only purchase model in greater detail.

Commercial Insurance Costs

Commercial coverage may process Dexcom through a pharmacy benefit, durable medical equipment supplier, or both. The route changes the claim, refill process, deductible, preferred pharmacy, and allowed quantity.

A flat pharmacy copay can produce a predictable monthly bill. A high-deductible plan may require the patient to pay a negotiated price until the deductible is met. Coinsurance charges a percentage of the plan’s allowed amount rather than a fixed dollar fee.

Prior authorization may require the prescriber to document the diabetes diagnosis, current treatment, insulin use, glucose-monitoring need, past hypoglycemia, or another plan-specific condition. An approval does not prove the copay will be low.

Ask the insurer for the exact product, quantity, refill interval, benefit channel, prior-authorization status, preferred pharmacy or supplier, deductible remaining, copay, and coinsurance. The phrase “Dexcom is covered” is incomplete without the patient amount.

Medicare Dexcom Coverage

Medicare Part B may cover a CGM and related supplies when a clinician orders it and the beneficiary meets the program criteria. Medicare states that an eligible person must use insulin or have a history of problematic hypoglycemia and must receive enough training to use the device as directed.

The prescribing clinician must also confirm that the patient meets the criteria. Medicare directs beneficiaries to use enrolled suppliers and to check whether the supplier accepts assignment on its CGM coverage page.

The patient may owe the Part B deductible and coinsurance based on the Medicare-approved amount. A Medigap policy, Medicare Advantage plan, Medicaid eligibility, or other secondary coverage can alter the amount left to pay.

Medicare coverage also affects device use. Dexcom states that Medicare requires use of a receiver, even when the patient also views readings through a compatible smartphone.

Pharmacy vs Medical Supplier

Some users obtain Dexcom sensors from a retail or mail-order pharmacy. Others receive supplies from a durable medical equipment distributor. One route can be much less expensive under a specific insurance plan.

The pharmacy route may offer faster pickup and manufacturer coupon processing. The medical-equipment route may be required by Medicare or by a commercial plan that classifies CGM as DME.

A distributor may ship a 30- or 90-day supply and handle authorization paperwork. That convenience can come with refill calls, documentation requests, delivery timing, and supplier-network restrictions.

Before changing suppliers, ask whether an open authorization, unfilled prescription, or recent shipment will block the new claim. Duplicate claims can delay access even when the prescription remains valid.

Hidden Dexcom Costs

The sensor copay is not always the complete diabetes-monitoring budget. A new user may need a clinic appointment, prescription, prior-authorization work, receiver, compatible smartphone, adhesive products, meter, test strips, lancets, or replacement supplies.

CGM does not remove every need for blood glucose testing. Dexcom directs users to use a meter when symptoms do not match readings or when the system does not provide the information needed for a treatment decision. Meter strips create a smaller recurring expense beside the CGM bill.

A new diabetes treatment plan may also include the cost of an insulin pump, pump infusion supplies, insulin, endocrinology visits, training, and periodic laboratory work. A CGM copay should not be confused with the complete treatment cost.

Adhesive overpatches and skin-preparation products may be needed when sensors loosen early or irritate the skin. Some are supplied by Dexcom, while third-party patches and barrier products create separate purchases.

Early Sensor Failure and Replacement

A sensor that fails early should not automatically be replaced at the patient’s expense. Dexcom provides technical support and may replace eligible products after reviewing the problem, device information, and circumstances.

Users can contact Dexcom through its product support service. Keeping the applicator, box, serial information, and failure details can help with the support request.

Insurance refill limits may prevent the pharmacy from dispensing another sensor early. A manufacturer replacement can protect the remaining prescribed supply when the failure meets replacement terms.

A sensor removed for imaging, surgery, adhesion problems, accidental dislodgement, or user error may be handled differently from a verified device failure. The support team, insurer, and prescriber can have separate rules.

Three Patient Cost Scenarios

Commercially insured user with a low copay: At $20 per month, twelve monthly fills cost $240 per year. No receiver is purchased because the user has a compatible phone.

Commercially insured user paying the cited lower-access price: At $89 per month, the annual sensor cost is $1,068. Adding a hypothetical $50 in patches and meter supplies brings the planning total to $1,118.

Adult buying Stelo without insurance: Four three-month subscription shipments cost $1,008 per year. That buyer does not submit prescription CGM claims and does not need a separate transmitter or receiver.

These cases should not be used to select a product. They show how insurance status, clinical use, and product category change the financial result.

ThePricer First-Year Example

Consider an insured Dexcom G7 user paying $45 per month. Twelve fills cost $540. Add $60 for meter strips and lancets used when needed, $48 for third-party overpatches, and one $35 prescription-related office copay.

• Dexcom G7 copays: $540
• Meter strips and lancets: $60
• Adhesive overpatches: $48
• Prescription visit copay: $35

The first-year monitoring total is $683. The Dexcom copays account for about 79% of that amount, while the supporting supplies and visit add $143.

ThePricer calculation: focusing only on the $45 monthly pharmacy charge understates the example by 26.5%. The added costs will not apply to every patient, but they show why the prescription copay and full monitoring budget are different figures.

How to Lower the Cost

Run the prescription through both the pharmacy and DME channels when the insurance plan permits it. Ask for the exact monthly patient price rather than a statement that the device is covered.

Use Dexcom’s official savings program when the plan has a high copay or excludes CGM. Coupon eligibility and government-insurance restrictions should be checked before relying on the advertised discount.

Ask the prescriber whether G7 15 Day is clinically appropriate and compatible with any connected insulin pump. Longer sensor wear may reduce replacement frequency, but the user should not switch solely for price.

FSA and HSA funds may be used for eligible diabetes devices and supplies. These accounts reduce taxable income but do not lower the price charged by the pharmacy.

Do not buy opened, expired, improperly stored, or diverted sensors from unverified sellers. A low marketplace price can lead to unusable products, no manufacturer support, or supplies that insurance will not replace.

When Dexcom Makes Financial Sense

Makes sense when:

• A clinician prescribes CGM for diabetes management.
• The user needs glucose trends, alerts, sharing, or supported pump integration.
• Insurance, Medicare, or savings support makes the recurring cost manageable.
• The user can obtain refills consistently and operate the system as directed.

Needs another cost check when:

• The deductible creates a much higher price than the advertised covered-user figure.
• The chosen phone or insulin pump is not compatible with the prescribed sensor.
• The pharmacy and DME supplier quote very different patient amounts.
• The buyer is comparing Stelo with prescription G7 without accounting for their different intended users and features.

Before Filling the Prescription

Confirm the exact model written on the prescription. Standard G7, G7 15 Day, G6, and Stelo do not use the same supply structure or eligibility rules.

Ask whether the price covers a 30-day or 90-day supply. A three-box checkout may represent three sensors for one month rather than three months of use.

Check whether a receiver is included, required, or billed separately. Verify smartphone support through Dexcom rather than relying only on the phone’s operating-system version.

Request the plan’s prior-authorization criteria and refill limits. Ask how early failures, travel refills, lost sensors, and plan changes are handled.

People comparing CGM with periodic laboratory monitoring can also review current blood test costs. An A1C test and a CGM answer different questions and should not be treated as substitute purchases without clinical guidance.

Answers to Common Questions

How much is Dexcom G7 per month?

Most users with CGM coverage pay $20 or less per month, according to Dexcom. Some commercially insured users may pay as little as $89 per month under another access pathway. Individual prices vary by plan.

How much does Dexcom cost without insurance?

There is no single nationwide checkout price. Dexcom’s current coupon reduces a 30-day sensor supply by $210 or more, with the final amount based on the pharmacy’s cash price.

Does Dexcom G7 need a transmitter?

No. Standard G7 and G7 15 Day combine the sensor and transmitter into one disposable unit.

Does Medicare cover Dexcom?

Medicare may cover Dexcom when a clinician orders it and the patient uses insulin or has a qualifying history of problematic hypoglycemia. Deductible, coinsurance, supplier, and plan rules can affect the out-of-pocket amount.

Is Stelo the same as Dexcom G7?

No. Stelo is an over-the-counter biosensor for eligible adults who do not use insulin. Prescription G7 products serve people with diabetes who need their features and meet the prescription requirements.

How much does Stelo cost?

Stelo costs $99 for a one-time one-month supply, $89 per month on monthly delivery, or $252 for a three-month subscription.
