  Scheduled appt. in **** ******* and confirmed they accepted my insurance. One week from my appt they called and said they discontinued offering coverage at the **** ******* location, so referred me to Eagan, and they confirmed they accepted my insurance as In Network. Complete all their online forms, set up portal, give all my personal history to them and drive 60 miles to my appointment this morning, only to be told they won’t accept my insurance but they’ll offer me a cash option of $375 just for the consultation. I was infuriated as asked why is this happening? All she said is if one clinic doesn’t accept it, none of them will, even though my insurance agent called them twice to confirm it’s covered in network, and it’s listed on their website that they accept it. I took 3 hours off of work, drove 120 miles round trip, only to find out they don’t and won’t cover me in network. There will never be any referrals or positive feedback from me on this company.

  NICE DOCTORS ETC. THE ISSUE IS THEY ARENT UPFRONT WITH THE PATIENT. I GOT CHECKED OUT AND MY CT SCAN DONE TO FIND OUT THEY REQUIRE 50% DOWN TO DO THE PROCEEDURE. NEVER HAVE I HAD TO PAY UPFRONT . FOR THIS REASON I AM GOING TO ANOTHER ENT DR *** GOT THE PROCEEDURE AUTHORIZED BY MY INSURANCE AND NO UPFRONT OUT OF THE POCKET EXPENSES. THEY ALSO REQUIRE A $100 BOOKING FEE, THIER BUSINES MODEL IS TERRIBLE, NEVER SEEN A OFFICE RUN LIKE THEY DO,

  The process did not cure nor treat my sleep apnea. I had a sinus procedure $15,000. I had a terrible recovery. I could not sleep after for almost a week. They were not sympathetic to my stress during recovery. The swelling was so bad I had panic attacks and could not sleep. I was fearful that I would never breathe normally again. Then I had a bad nose bleed when a clot came off. Yet every time I called them and had an in office visit I felt like my concerns were brushed off. Then after my last appointment they tell that the sinus procedure was not the 'cure' that I would need an additional $5000 mouth guard that I would have to wear for the rest of my life. I did try wearing it but after a few weeks I still had bad snoring. I asked for post sleep study to see if it was at all effective. They said that was not required. Now I see why cause it does not work! In fact my dentist warned me to NOT wear the mouth piece cause it would ruin my bite. So the whole $20,000 was a waste. Do not have the procedure. Just get a **** and live with it. Less $ and hassle.

  Do not go to Advent. Take a look at the rest of the reviews. I am writing this on behalf of my wife who had a procedure to turbinate reduction to help stop snoring. She had to perform multiple studies and tests which cost us thousands of dollars ($1,000's) before they determined she needed to have the inside of her nose "scraped". During this lengthy and expensive process, when she had questions, she was never able to get through to anyone and there were dozens of phone numbers and multiple different people that she had to talk to, none of which knew what the other person was doing, and none of them every answered their phone or returned our calls.Finally, after getting the procedure scheduled, we had to pay the "expected" insurance upfront. I was told emphatically - because I asked to clarify - that this was the only and final payment. We also had a letter stating as such that we received. This was the calculated insurance payment. We were not able to go thru with the procedure unless we paid the amount in full that day. (That should have been a red flag, but because I was tired of my wife snoring, and I'd heard good things about Advent, I paid). That was well over $1,000.She still snores, albeit, less.They then sent me a bill about a month later, which had gone thru insurance. It was a statement that showed their cost and my payment. It was over $1,000 but less than my payment on the day of the procedure. Why submit to insurance if I paid already? I tried calling their "billing" #... GOOD LUCK. They only allow you to leave a voicemail and DO NOT ANSWER THEIR PHONES, nor do they call back. You cannot even wait on hold, as they hang up after one minute. I am not paying a duplicate bill. In fact, they OWE me money since insurance charged less than the day I paid. DO NOT GO TO ADVENT.

  Don't do it. They rush you right in wifh no upfront pricing. First appointment with insurance was over $270.00. I just wanted to get some information, see what they offered, but it's like going to a used car lot, before you know it, they've sold your car you didn't want. I question them again about given me upfront pricing for the upcoming appointments.Never heard back from them . I canceled the rest of the appointments they had set up. Ask them to give me a good reason why the first appointment so expensive. Still waiting for a call back, which will never happen. Go to your regular doctor or ENT. I'm not even sure the person I seen was a real certified doctor. When I first got there, there was somebody there trying to figure out about making payments on their account. I should've walked right out the door then I got a very uneasy feeling. Don't be fooled like me.Stay far away!!!

  So expensive. They don't make costs clear up-front, my **** **** *** barely covered their expenses, after sinking $1000+ between visits and a "sleep study" (which can be purchased online for $150 and was billed at over $1000) I found myself out of options as could not afford to move forward, after gathering funds I was told I needed to restart the entire process. I have no idea if their solutions work as I never made it that far, maybe if money is not an issue they guys are great but I feel like they should be more clear, even with insurance they are going to extract $2500-3000 from you before you get any help.

  My husband has used the traditional hose and mask c-pap set--up for over 20 years. Although it works well, he heard the commercials from Advent regarding other c-pap options. I went to all appointments with my husband, so I do know what I'm talking about. We went in and the PA immediately started talking about sinus surgery, tacking a sleep study on the end of everything else. The everything else included what it took to get ******** to pay for the sinus surgery. They ordered a round if antibiotics( what ever happened to not prescribing antibiotics unless needed?) My husband has never had a sinus infection or problem in the 25 years I've known him. Then came the nasal spray and the sinus scan. Then, finally, an at home sleep study. Please remember, we went there only for the c-pap issue. After all this, we get a call that ******** has approved the surgery and a date was set. My husband asked about the sleep study and was told that would have to be talked about in office. So now we have a surgery scheduled when there is no problem. If there were sinus or breathing issues, the c-pap machine would not have been so successful all those years. We went for the final office visit and the PA talked about the surgery only, until we finally asked about the sleep study. Oh yes, the sleep study. My husband's sleep apnea is so severe that none of the less cumbersome alternatives would work, he should stay with the system he already had. So, we went in for the c-pap issue and found that they zeroed in on a sinus issue that wasn't there, got ******** to approve it and set a date. Is this a form of ******** fraud? There was no surgery needed, my husband canceled it and we left with no other options for the sleep apnea. We are not upset about the outcome of the sleep study or the recommendation. We are upset that the PA immediately set about doing what had to be done to get ******** to pay for a procedure that was not needed. Be very careful using this business.

  Advent Knows Buyer Beware For the initial 30 minute visit, they charged my insurance company $959, and i didn't see a doctor. The physician assistants came in and did the tests. Response was we don't see anything right now, until you complete more testing. Nope, i didnt want to incur any extra costs for my initial visit because i didnt believe they had an approach for me. Now i am responsible for $365 in deductible visit. 30 minutes of a physician assistants time, and no answers.Advent Doesn't Know

  Horrible experience. Charged my insurance company 4x what was customary, and left me with a hefty co-pay, of which I told them to ***** it. This is a slick marketing company desguised as an ENT practice.

  I was just curious if there was something besides my deviated septum that caused difficulty in breathing from my left nostril. I know I could have corrective surgery but perhaps by chance something simpler. So I scheduled a visit just to have them look in my nose and see what they thought. I have a PPO so I thought an office visit shouldnt be very expensive. During the office visit a little light and camera were inserted in my nose. The health professional ( not a MD or DO) said I would then need to schedule some kind of head scan. I really didnt want to get that involved just hoping for a quick look on options. I never scheduled the scan and thought some day I would go see a ENT if I really wanted the time and expense of the corrective procedure. I just received a bill for $239 after insurance was billed $700 for a surgical procedure plus office visit charges to look in my nose. I was not informed that this was a procedure not covered as included in an office visit. Place seems like a scam to me.
