Dexcom G7 10-Day vs G7 15 Day: Cost and Differences

By Paragon Diabetic Supply · Updated September 26, 2026

Dexcom G7 and Dexcom G7 15 Day are different sensor models. The standard G7 has a shorter wear period and warmup; G7 15 Day is designed for longer wear in adults. Before comparing prices, confirm the exact model that fits your prescription and compatible equipment.

G7 10-day vs G7 15 Day: key differences

  • Standard Dexcom G7: up to 10 days of wear, a 12-hour grace period, a 30-minute warmup, and an age indication of 2 years and older.
  • Dexcom G7 15 Day: up to 15 days of wear, a 12-hour grace period, a 60-minute warmup, and an age indication of 18 years and older.

These specifications come from Dexcom’s model comparison. The longer-wear model does not extend the approved wear time of a standard G7 sensor. Follow the instructions for the exact product you receive.

Compare cash prices over the same period

Paragon’s one-time single-sensor prices checked on September 26, 2026 were:

At those individual-sensor prices, the calculated 30-day totals differ by one cent. A higher price per sensor therefore does not necessarily mean a higher cost over the same number of days. The 15-day model requires fewer scheduled sensor changes over that period, but model suitability and compatibility still matter.

These are budgeting examples, not a guaranteed monthly bill. They assume every sensor lasts its full stated wear period, exclude grace periods from the calculation, and exclude taxes, shipping, receivers, and subscription or multipack discounts. Calendar months vary in length. Prices and availability can change; use the current product page and checkout total before ordering.

Check compatibility before switching

Do not choose a replacement from the words “G7” alone. Confirm the full sensor name, phone and operating system, app or receiver requirements, and any connected insulin pump requirements. Check Dexcom’s current device compatibility information and your pump manufacturer’s current instructions. Ask your healthcare professional about a model change.

One-time orders and subscriptions

Paragon offers cash-pay ordering through our website. Compare the quantity in the listing with the quantity needed for your planned period of use. A delivery every month is a shipping interval; it does not by itself mean the order contains enough sensors for an entire month. Review the sensor count and selected purchase option before placing an order.

Before you place your order

  • Confirm the exact G7 model and the number of sensors in the listing.
  • Choose a one-time purchase or review the quantity and delivery interval of a subscription.
  • Allow for typical shipping of 3–5 business days. Orders of $75 or more qualify for free standard shipping. For special shipping, contact us before ordering.
  • Keep packages unopened until you have checked the model. Review our return policy before purchasing.

Questions before ordering

Is G7 15 Day simply a standard G7 worn longer?

No. Order the specifically labeled G7 15 Day product if that is the model you need. Do not extend a standard sensor beyond its instructions.

Which model has the lower cash cost?

Compare the total for the same wear period and purchase option. At the dated prices above, the 30-day individual-sensor totals are essentially equal. A pack discount or subscription selection may change that comparison.

Can Paragon help me check the listing?

Yes. Contact Paragon Diabetic Supply for product-listing, package-quantity and order questions. Clinical suitability should be discussed with your healthcare professional. Follow the manufacturer’s instructions and safety information.
