The American Association of Clinical Endocrinology (AACE) recommends real-time continuous glucose monitoring like Dexcom G7 for insulin-using adults ages 65 and older to achieve3:

  • Improved glycemic control
  • Reduced episodes of severe hypoglycemia
  • Improved quality of life





Studies show that Dexcom CGM is
proven to increase time in range4-8

Studies show that Dexcom CGM use is clinically proven to increase time in range.4-8 Time in range is a powerful supplement to A1C because it shows a more complete picture of changes in glucose levels. Since A1C is a three-month average, it doesn’t give insight into potentially dangerous high and low glucose variations.

40% in range
100% in range


Retrospective review of glucose data from Dexcom G6 can identify patterns of hyper- and hypoglycemia, as well as glycemic excursions to help guide treatment decisions.


Case studies: Patients who can benefit from CGM

Below are some examples of patients living with type 1 and type 2 diabetes (T1D/T2D), each with different backgrounds and treatment plans. Read each scenario to learn how Dexcom CGM can help different patient types.

Hypothetical patient profiles

Claudia – T2D with hypoglycemia

Patient background

dexcom g7 medicare continuous glucose monitor

Claudia, a 72-year-old female who lives alone and loves to garden. She has a history of level 3 hypoglycemia that required assistance.

Current treatment: Glipizide and metformin

Current A1C: 7.4%


Claudia was planting flowers in her yard when she felt shaky and decided to sit down. A neighbor saw her sitting and looking disoriented and went over to see if she was ok. Claudia said she needed juice or the sugar tablets, which her neighbor quickly retrieved from her kitchen. She drank 4 ounces of juice and ate 2 glucose tabs. Once she felt a bit better, she realized she took her sulfonylurea at lunchtime but got sidetracked planting before she ate. She knew she had experienced very low glucose and decided to call her doctor to discuss. 

She went in for an appointment the next day and told her doctor she’s had similar episodes before, and thinks she might have also been low those other times. Her doctor documented in the office visit note that Claudia has had level 3 hypoglycemia that required assistance, then prescribed Dexcom G7. She started on Dexcom G7 as soon as her shipment arrived.

Why Dexcom G7 was prescribed

Expanded Medicare coverage criteria* includes level 3 hypoglycemic events that require assistance and are documented in the office note.

How Dexcom CGM helped

Claudia now uses Dexcom G7 consistently and gets alerts if her glucose drops quickly or will be urgently low soon, so she can take action to avoid hypoglycemia. She also gets a low alert that she set to go off when she drops to 85 mg/dL. 

Another feature of Dexcom G7 that Claudia says eases her mind and gives her comfort is that the Dexcom G7 mobile app allows her to share her CGM data with up to 10 followers.|| At this time, her neighbor and daughter follow her and get alerted if she is low so they can check in on her.


Steve – T2D, prescribed basal and mealtime insulin

Patient background

dexcom medicare patient

Steve, a 68-year-old male who is very active. Despite being prescribed basal and mealtime insulin, he doesn’t take it due to fear of hypoglycemia.

Current treatment: Metformin, basal insulin (degludec), and meal-time insulin (lispro)

Current A1C: 8.9%


Steve is competitive in tennis and teaches tennis lessons. He would run his glucose levels “really high” by not taking meal-time insulin due to fear of hypoglycemia while competing.  Steve’s doctor asked him to check his glucose prior to tennis competitions and note what his numbers generally were. He was consistently over 300 mg/dL and comfortable with this because he knew he didn’t have to worry about having a low.  

His doctor prescribed Dexcom G7, so Steve then had what he referred to as a “safety net” with the Urgent Low Soon and Falling Rate alerts. His first goal was for his glucose number to be less than 200 mg/dL prior to his competitions.

Why Dexcom G7 was prescribed

Expanded Medicare coverage criteria* includes anyone with diabetes treated with any insulin.

How Dexcom CGM helped

Steve was able to better manage his glucose levels prior to exercise and increase his time in range because he was ok starting tennis at a lower glucose level. He also has less frequent lows, because now he knows he can eat carbs when he gets an Urgent Low Soon alert. Dexcom G7 alerts help him worry less and feel better out on the court knowing he’ll get an alert if he is going too low. 

This was a gradual process of adjusting his alerts and glucose goals. Once he started competing in a glucose range that wasn’t so high, Steve reported that he felt better and his performance improved. He also made other changes to food choices that he noticed were giving him high glucose after eating. Looking at trends and patterns on Dexcom Clarity reports helps Steve see how much time he is spending in target range as well as where he could improve.


Rebecca – T2D on basal insulin

Patient background

dexcom medicare

Rebecca is a 67-year-old female who was diagnosed with T2D 12 years ago.

Current treatment: Metformin 1000 mg BID, Sitagliptin 100 mg QD, Glimepiride 4 mg BID, basal insulin (glargine) 36 units QPM

Current A1C: 9.8%


Rebecca is motivated to manage diabetes but struggles with eating lower carbohydrate foods consistently. She’s busy with volunteering activities and her new post-retirement social life. When Rebecca was working, she kept her blood glucose meter at her desk and would check her glucose 1-3 times daily. Nowadays, she often forgets to bring the meter with her when she’s out and about.

Why Dexcom G7 was prescribed

Rebecca’s primary care provider (PCP) recognizes her desire to better manage her diabetes and wants to provide a tool that shows her glucose patterns and trends. Her PCP believes Rebecca can use that information to adjust her medications and improve overall glycemic management. In addition, expanded Medicare coverage criteria* includes anyone with diabetes treated with any type of insulin.

How Dexcom CGM helped

Glucose patterns and trends shown on Dexcom Clarity reports allowed Rebecca’s PCP to see what areas to improve and made medication adjustments to address her persistent evening and overnight hyperglycemia.# Her new medication plan included changing glimepiride to dapagliflozin (SGLT-2i), changing sitagliptin to semaglutide (GLP-1 RA) 0.25 mg titrated up to 1 mg weekly, continue on Dexcom G7, and follow up in 3 months. 

At 3-month office visit, Rebecca’s A1C had decreased to 7.2% with improved postprandial hyperglycemia. Her Dexcom Clarity reports showed overnight hypoglycemia and glycemic variability. Her PCP recommended reducing her basal insulin to 18 units QPM and continuing with lifestyle modifications. Rebecca is now using Dexcom G7 to guide meal choices and thanks to Dexcom G7 alerts, she can intervene earlier to prevent or minimize hypoglycemia episodes.

Doug – T1D on MDI

Patient background

dexcom medicare user

Doug is a 68-year-old male who was diagnosed with type 1 diabetes 47 years ago.

Current treatment: Degludec 40 units daily at bedtime, Aspart 1 unit per 10 grams carbohydrate plus correction of 1 unit per 50 mg/dL over 150 mg/dL at meals

Current A1C: 7.2%


Doug has been living with type 1 diabetes since early adulthood when he was diagnosed. He has been on multiple daily insulin injections and using a blood glucose meter (BGM) to check his glucose numbers since diagnosis and his outlook is, “if it’s working, why change what I’m doing?” Doug eats well-balanced meals and feels he’s doing everything he can to take care of his diabetes. 

Sometimes, Doug is unsure if he is experiencing hypoglycemia and it worries his wife that he’s not as aware of the symptoms as he used to be. He is stubbornly independent and doesn’t want much help from others, especially when it comes to diabetes management.

Why Dexcom G7 was prescribed

Doug told his primary care provider that he feels like his glucose numbers aren’t as steady as they used to be, and he can’t figure out why. His doctor told him that Dexcom CGM could give them both insight into what’s happening with his glucose levels in between fingerstick checks with his BGM. 

Doug was curious to see how CGM could help, and decided to give it a try since it’s covered by Medicare.*

How Dexcom CGM helped

For the first time since being diagnosed, Doug was able to get a clearer picture of what was happening with his glucose levels throughout the day and night. He had no idea that eating oatmeal with banana slices for breakfast caused his glucose to spike to over 250 mg/dL, and it took a few hours to get back in range. 

Before CGM, Doug only saw the numbers in the low 100s before he ate and the 100s before lunch. Doug admits, “I was under the impression that all my blood sugars were in range based on the numbers I was seeing on my meter, and my A1C being around 7%. I can now see that I have some pretty big spikes after what I thought were healthy meals. I’m going to experiment to see what I can eat for breakfast that won’t cause such a spike.” Doug was surprised that he felt comfort in being able to always see his current glucose number and the direction it’s heading. This caused him to worry less when he was busy and not wanting to interrupt his day to use his BGM. 

Doug’s wife was glad he eventually allowed her to follow his Dexcom G7 data and be alerted if he gets an Urgent Low Alarm. Doug likes that he can decide what alerts his wife receives, and that she’s not nagging him as much about his numbers because she can see them on the Dexcom Follow app.


My patient is insured by Medicare. Are they required to get a Dexcom G7 receiver? Will Medicare pay for a new receiver if they already have a Dexcom G6 receiver?

In order to qualify for Medicare coverage for Dexcom G7 supplies, Medicare requires that they have a receiver that is compatible with Dexcom G7 and that they use that receiver with their supplies, even if they also use a compatible smart device, regardless of whether they use an insulin pump.  If Medicare does not pay for a new receiver, Dexcom has launched a new upgrade program that includes a Dexcom G7 receiver at no charge for eligible customers.  

How does my patient know which Dexcom receiver they have? 

The two receivers have different hardware.*  Please refer to the user guides for information about the hardware.

Will Dexcom provide diabetes testing supplies?

No. Blood glucose monitoring (BGM) supplies are not included in the CGM product shipments because Dexcom G6 and Dexcom G7 do not require fingerstick calibrations.* Any BGM testing supplies need to be purchased.   

*If your patient’s glucose alerts and readings from the Dexcom G6 or Dexcom G7 do not match symptoms or expectations, please use a blood glucose meter to make diabetes treatment decisions. 

How does my patient view glucose data? 

You can view your patient’s glucose data through the Dexcom G6 or Dexcom G7 Apps, your Dexcom G6 or Dexcom G7 receiver, and the Clarity Mobile or Desktop applications. 

Medicare does not cover Dexcom G6 or Dexcom G7 CGM supplies that are used only with a smartphone or other mobile device. Failure to use your receiver will result in loss of Medicare coverage for your Dexcom G6 or Dexcom G7 CGM supplies. 

What is the CMS policy?

Coverage of CGM system supplies and accessories are available for those therapeutic CGM systems where the beneficiary uses a receiver classified as DME to display glucose data. There is no Medicare benefit for supplies used with equipment that is not classified as DME. However, Medicare coverage is available for the CGM system supplies and accessories if a non-DME device (smartphone, smart watch, tablet, etc.) is used in conjunction with the durable CGM receiver. Coverage of CGM system supplies and accessories are available for those therapeutic CGM systems where the beneficiary uses a receiver classified as DME to display glucose data. If a beneficiary intends to never use a receiver classified as DME as the display device, the supplies and accessories are not covered by Medicare. 

Here are some examples of how a Medicare patient may use a smart device with their receiver: 

  • A patient uses both a receiver and a smartphone throughout the day 

  • A patient uses a receiver some days and their smartphone other days  

Patients should reach out to 1-800-MEDICARE with any questions about the Medicare coverage requirements for Dexcom CGM.
