Great people always polite and fill in the gaps for you. Take the time to answer all the questions so you do not. have to call back

Been a Diabetic II for twelve years, Dexcom G7 changed my life and ADS has sustained the quality afforded me with Dexcom by carefully overseeing prescriptions, refills, and incredibly efficient deliveries and communication. read more

ADS has been a great experience for us. We had a terrible time keeping my husband's diabetes in check. This product has made it so simple and the service from the agents, if we have a problem, is wonderful. Things are resolved quickly. read more

Representatives are more than happy to go above and beyond for me. Great experience with every interaction. I only get my Dexcom G7 Sensors from here, so I can only speak on this. My experience has been mostly automatic, with the exception of when my doctor sends in a new request for insurance justification and ADS does not identify that the request is new and needs updating. I then would have to call and let the representative to check the referral carefully. After which they would process the request. I had to do this twice when my insurance would not approve and my doctor had to change my regimine. The value is incredible. I remember paying so much more when getting my monthly supply at my local pharmacy. Now that my account is setup and no updates to my insurance is needed, I receive excellent service from ADS and that just makes my life easier. Thank you, ADS! read more

Terrible company. 5+ hours. 10 phone calls. 8 different "escalation specialists." 8 Promises. ZERO results. Go with anybody else if you can. Representatives were not even aware that their CEO had changed a year ago. Or that the company had been acquired by Cardinal Health Services. New CEO of ADS is Anthony Alvarez. Contact him through LinkedIn or Facebook. read more

I needed supplies for my insulin pump after I changed Medicare insurance from an Advantage plan to traditional Medicare with a supplemental plan. Instead of telling me exactly what Medicare required for approval they dragged it out piecemeal. So instead of taking a couple of weeks to gather all the documentation and blood test results, it took multiple months. Then their customer service representatives outright lied to me on the phone about my order. They incorrectly tried to place my order as for a new insulin pump plus supplies. I did not need an insulin pump, and Medicare was not going to pay for a new one. I never requested a new pump nor did my endocrinologist. The natural result was that the order was cancelled. A neat trick to screw over a customer (I have worked for Medicare in the past and saw some of my colleagues play such games). I just needed supplies. Then I was hung up on five times in one day, even though I was not rude, I did not use foul language, and I tried to be polite and patient. Then I found out the supplies I needed were actually on backorder. No one called to let me know that. I was transferred to talk to a pharmacist to talk about possible alternatives to the supplies on backorder. After an hour of being on hold, the call was cut off. On the sixth call in one day, I finally reached a representative who was actually interested in helping me and in placing my order for insulin pump supplies. Time will tell if it actually comes about as promised. I cannot recommend doing business with this supplier. Find an alternative before you are forced to endure their incompetence and rudeness. read more

Caution: Refrain from Utilizing This Pharmacy If you have alternative options, I strongly advise against using this pharmacy. I have been dealing with this company since February, when my doctor recommended ordering pump supplies from ADS. ADS is the most unsatisfactory pharmacy I have encountered. They only accept requests via phone and email. They have consistently failed to fulfill their promises. Despite calling almost every other day for the past month, they have repeatedly assured me that the pump supplies would be shipped that day. However, I have yet to receive them. Now they claim they are having an internal issue, they can't seem to resolve. I was assigned a case manager named Gabriella, but I have never spoken with or been able to reach her. I was informed that she would contact me back a month ago, and every time since. I have spoken with Jen, Evelyn, John Marica, and Mareesha. Marcia is the lead, for whatever that means to them, she doesn't seem to know more of have more authority. They seem to prefer to get you off the phone as quick as possible. And they ask the same set of questions each time, which seems like they aren't actually recorded my previous requests and answers. Furthermore, ADS attempted to charge me $120 per Dexcom CGM, despite all other pharmacies charging only ~$10 per unit. I know this is an insurance item but this pricing strategy suggests a lack of concern for their customers and a deliberate attempt to conceal it. I had to push hard to them to cancel this order I didn't approve. They don't want to send the pump supplies, just whatever they can make the most profit from. In light of these issues, I am filing an Independent Medical Review (IMR) with the California Department of Managed Health Care (DMHC). If you are experiencing similar problems with this pharmacy, I strongly recommend that you consider this option. read more

Very efficient and knowledgeable. I received my product within a reasonable amount of time.

No one actually takes you seriously. All calls go to India. HIPAA violators. Once you finally get someone in the US, you are lied to. The 5 start reviews probably come from employees forced to review. read more

After failure to properly contact my insurance, causing an extreme delay in shipping my products, I was to be sent an emergency sensor. But when I received the box, all that was in, it was the paperwork. So after spending several hours on the phone, trying to get my pump supply order straightened out, they sent me a box with nothing in it. This is not the first time I've had problems with them. read more

After years of hassle-free service, all of a sudden ADS has gone bad! I switched over to MediCare recently, and since then, have had all sorts of problems: delays in getting insurance approval, conflicting messages from reps on separate phone calls, delays, etc. At one point, I went a week without any CGM and had to use test strips (welcome back to the 20th century). I'm done with ADS. Going to check out Byram... read more

Horrible! I've called 6 times to get my refills sent. Twice I had Humana on the phone to give them the authorization needed and they still will not ship. Ive gotten 6 different emails saying they're sending them. But when you call you get know here. Also everyone you talk to speaks broken English at best! I'm done with this! I'm taking business elsewhere. read more

Absolutely AVOID. I called at the BEGINNING OF MARCH, 2026. And have played phone tag with FIVE(5) representatives. Being told "this is being held up by the supervisor". So today, APRIL 13TH, 2026, I call and ask for a supervisor. To which ALL OF A SUDDEN I am told the EXACT department who needs to handle my need. This is getting ADDITIONAL SUPPLIES that is NEEDED for my INSULIN PUMP. And am told "you will have to pay out of pocket." I expressed that had THEY at ANY POINT contacted me back, I could have SWITCHED OUT THE UNUSED SUPPLIES like THEY wanted, instead of having to use it (because fun fact, they wanted me to send it back before shipping me out new supplies) that could have been done. BUT since I was ring around the rosy'd I had to use said supplies. I questioned if they would contact my insurance to see if things could be adjusted. In which i was told no, because the original prescription said x on it. Aka THEY REFUSED TO TRY AND DO THEIR JOB! The absolute WORSE company known to mankind. They DO NOT CARE about you they care about money. Refusing to question my insurance, which fun fact WOULD PAY YOU, if they would add more infusion sets and reservoirs is NEGLIGENCE! How can you be a SUPPLIES COMPANY and decide that you will not contact insurance to get your customer needed SUPPLIES! read more

AVOID AT ALL COST. I have now gone almost half a month without my supplies due to the incompetence and negligence of ADS causing medical complications. This company does NOT care about their patients at all, have been dealing with nothing but issues since day one. Please, save yourself the hassle and go anywhere else, anywhere at all. read more

Terrible company. They ONLY care about the $$$$, AT THE EXPENSE of your health. They are rude, incompetent and barely understand the english language. AVOID. read more

By far the worst company I've had to deal with in a long time. My insurance company arranged to have them supply CGM's to me, and orders were often shipped at the last possible moment and then arrived late, after the one I was wearing timed out. A few times, the CGM fell off and I called ADS and after 25 or 30 minutes on the phone I was able to get CS to send me a replacement. The third time it happened I called and they refused to send a replacement...instead, they told me that I had to call the manufacturer to see if they would send a replacement. That took almost 3 days to get a response but Abbott did send a replacement. After that sh!tsh0w, I called my insurance provider and they told me that they couldn't understand how I ended up with ADS as my supplier because my insurer has a contract with CVS and recommended I change to them, so the rep switched to them as my provider and I could simply go to their location a few blocks away and pick my supply up from them. My insurance rep also told me that I have zero co-pay for CGM;s which surprised me because ADS has been billing me about $110 in copay each time they ship an order. I then called ADS and cancelled all future orders and to not send the next order which was due to ship in about 3 days from the day I called to cancel. Well, guess what? They shipped the order anyway. I get emailed updates with tracking on any incoming mail and packages to my address and I could see the order was en route but at a facility in Texas. About a day later, I received an email that the shipment was canceled and being returned to the sender. Despite canceling and them clawing the shipment back before it ever got to me, they sent me a bill for a $110 co-pay. I assumed they would have figured it out and dropped the co-pay bill. Nope. Instead, they have continuously sent me mailed collection notices and emails claiming I owe them the $110.00. They also call me about ever other day with a recorded message that gives no opportunity to respond. It is a broadcast only call. It's so persistent that now I don't answer any calls anymore unless it's known family or friends. I finally called their customer service and (after holding for a while) the rep told me that they showed the order WAS delivered (it wasn't!) and that I would have to call shipping to make any claims and sort it out. That infuriated me (sorry to the rep, if you're reading this) because after already spending too much of MY time trying to correct it I became angry and unloaded with all the worst words...but this is another example of how mismanaged and unprofessional the company is, as a whole. First, their service and shipping delays caused me to have periods of days at a time where I had no CGM and Second, they refused to help me with a replacement for a defective monitor (even though they were my supplier) and directed me to the manufacture which delayed the replacement by almost 10 days!, then they charged me a co-pay when my insurer assures me I have a zero co-pay (for the record, I have been using CVS as my supplier since November now and have never paid a copay to them) and finally, when they screw up a shipment that was canceled and returned to them they are insisting I still have a co-pay for that order and have been persistently trying to collect. I just read a few reviews also complaining about slow and late ships so I wanted to warn any future customers of this so they can find a better supplier. Incidentally, they deserve no stars but I had to choose at least one star in order to post this review. read more

ADS sends us SMS messages asking us to authorize expenditures for supplies but without telling us which supplies they're going to send us, when they're going to send it, or how much they're going to charge us. This is unacceptable because we need to know what, when, and how much. Why do they say, "click here and we'll charge what we want," instead of "click here and we'll send you x boxes of A and y boxes of B for $[billling amount]"? It shows that they're not willing be upfront and honest about what they're going to do. Having to do business with companies like ADS is another burden of having Type 1. read more

Better than my local pharmacist Great experience overall Was able to do everything over the phone and I received my order very fast read more

Yet again ADS has not followed through with my supplies! Always an excuse why my supplies aren't shipping in a timely manner. I'd use another company if it was possible! Being held Hostage by their incompetency is maddening! Every time my supplies aren't shipping on time. Disgusting! read more

I have been trying to work with ADS for 2.5 months now to get my prescription for a CGM filled through medicare. The interface between ADS and my doctors office is pathetic. ADS keeps telling me that the script that my doctor is writing isn't correct and needs to be submitted via a form that ADS uses. My doctor tells me that he has filled out that form and returned it at least twice now and ADS still say's that they haven't received anything. At this point my doctor is no longer replying to them as he claims that he has provided what every other medicare provider requires and there have been on issues, only with ADS. read more

Worst of the worst. They don't know what they are doing with diabetes supplies and Medicare. I have spent hours on the phone with them regarding CGM approval. They claimed Medicare denied my coverage. In fact, they never contacted Medicare. The reps give out conflicting information and make up incorrect answers. Worst of the worst...a call center in the Phillipines...everyone reading from screens. Zero knowledge. read more

This is the third time in less than a year my supplies have been late. They say they take complaints very seriously but their record says otherwise. read more

When my husband ordered 6 months ago, it was a nightmare. He was without a CGM for weeks while waiting for this company to get their act together. Finally, the order was sent out, and we were assured by a supervisor that these issues would not happen again. Lie, lies, and more lies! We are going through exactly the same problems as before. First got an email stating order would be shipped on 1/21. If there was a problem, they would "reach out to us promptly." On 1/22, we got a call that they needed medical records, records that they never requested from the doctor. OMFG!!! I have begged our insurance carrier to go with a different company, but no luck so far. If you can go with a different company, DO IT! This one doesn't care if you live or die. read more

Phone personnel was extremely helpful & friendly. Delivery came faster than expected!

Absolutely awful company. I have been trying to return this pump and get a new one for 3 weeks. After being on the phone for about 12 hours having the same exact conversation, I GIVE UP! There is no note taking from the calls so everyone I talk to is starting from scratch and knows nothing! I never get the call backs from supervisors that I have been promised. Absolute worst customer experience I have had in my entire life. Avoid this company if you possibly can. Update: They sent me 1/3 of the supplies I need simply to exist. Awful company. Expect to do their job for them. Update #2: Was transferred to the US call center where I was told I would get my infusion sets! HOORAY! That was 6 days ago when I was told they would be "overnighted". After emailing, messaging and otherwise trying to contact this company, I am now on the phone with a non US call center who tell me that the infusion sets are 'Out of stock". I am on my last set. THIS COMPANY SHOULD BE AVOIDED AT ALL COSTS. Absolutely incredibly inept. I can't express my disdain for this company. They cut corners at every turn at the expense of their customers. Avoid at all costs. update #3: I HAVE EMAILED THAT BS ADDRESS YOU RESPONDED WITH. Multiple times! I never hear back from you people. Absolutely awful company! update #4: I still have not received a refund for the pump I returned 6 months ago. I was assigned and "advocate" and the company is saying that no refund is due because I returned the pump!?! So I am out 4k and I had to pay for my replacement pump? This is criminal and I will be pursuing legal action. STAY AWAY FROM THIS COMPANY! read more

they are a great company. on time delivery. also checking for you. They always have supplies for you.

I haven't seen any supplies show up. It is the holiday weekend. Unknown Unknown Your asking me questions and I haven't received any supplies yet. read more

I had a little difficulty working with ADS when my physician changed my testing method. Also I just received my supply of test strips in a HUGE box that was impossible to open without a carpet knife. Why such a gigantic box for 4 little boxes of viles? read more

Advanced Diabetes Supply - Medical Supplies Near Me - Carlsbad, California

See all

Avoid this company if at all possible. I'm genuinely mind-blown at how terrible their service is. They sent me continuous glucose monitors that were far too close to expiration without my authorization and billed the wrong insurance. A rep told me they would send a replacement shipment, but it never arrived and no one followed up. When I checked in again, they said I needed to speak with a supervisor who would call me--no call ever came. After multiple attempts, I finally spoke with a supervisor, but there were roosters screaming in the background, and it was extremely hard to hear them. They were mumbling, giggling, and acting completely unprofessional, with other phone conversations happening in the background. There was zero accountability or empathy. It appears everything is outsourced to the Philippines and very poorly managed. Do not put your health in the hands of this company. read more

Excellent communication. Fast service. Kept in contact with me throughout the entire process read more

I had a terrible experience with Advanced Diabetes Supply (ADS). My doctor referred me to them on June 4th, 2025, to get my Freestyle Libre 3 glucose monitor. Almost 2 months later, I still haven't received my supplies. They kept claiming I have a past-due balance. Even though they can confirm that I've never ordered anything from them before, and my insurance covers the CGM 100%. They also tried to charge me a copay when there shouldn't be one. I called them numerous times, and every time they either gave me the runaround or said they'd look into it but never followed up. It's now July 28th, and nothing has been resolved. I'm extremely disappointed. Avoid this company if you want reliable service for critical medical supplies. read more

Awesome products that have helped keep my A1C in check. The value was incredibly low considering how much a similar kit would have cost. The customer service was great and very friendly. read more

Terrible. My mom's supplies weren't sent so we called on a Monday, rep said it was late and that they would send overnight shipping, provided no tracking info, and it's now Friday night. They are based in San Diego and my mom is in LA..... I hope she is still alive by the time her supplies arrive. Thanks Advanced Diabetes! read more

The foreign out of the country representatives seem like they've had NO TRAINING. After I was asked for my name for the 4th time during the call I asked for a manager. Of course she couldn't find one. Another representative called me at 9:30pm PST as I sent in a request for a call back when their phone lines were busy. This woman wasn't much better than the first. I still have not gotten my supplies. You need to provide a corporate number to the United States. The Worst out of Country service I've ever had. Plus the calls were noisy I don't know if it's a call center or their homes they call from. read more

This company is so user friendly. The product was here in a few days it's very easy to reorder

Horrible company and services. Patients need their supplies but they can't deliver the products on time. Multiple times, we have had to call because we were out of supplies but they just happen to be "processing" it on the same day. Coincidence? They can't set up and schedule and supplies have come either on the same day we're out or late. It continuously causes stress and anxiety for us because we've had to remind them to do their jobs and deliver much needed supplies. This company toys with patients health and don't care about their services. CS rep every single time: we apologize and ensure it wont happen again. Until the the next time Oh and good luck if you have to update insurance. You can try updating them, but they'll make you do all the work in calling all the insurances about the changes. They'll then make you call again to verify because no one at this company knows how to their jobs read more

They do not answer the phone at all. They rarely return calls. When they do it's someone that often can't help because it's a different department. They send automated calls that don't help. They charged my card, then said I didn't pay, and I'm wasting my time straightening it out because they won't answer. This company could not be worse. I just transferred my prescription. read more

Support service and information. Mistake for not using them sooner. Prompt service and follow up.

The customer service is stellar. They always have been helpful and knowledgeable. They address my concerns immediately. ADS has been paramount in managing my condition... Thank you!!! read more
