  After the initial visit, Advent Knows clinic dumped me off to the office staff to schedule; they only wanted the full payment upfront before submitting it to insurance. The procedure was scheduled after paying a minimum deposit, which seems reasonable. However, upon arriving for my procedure, they would not proceed unless I paid the entire suspected insurance payment deductible of $4000 before even submitting it to insurance. There is a huge disconnect between the Hippocratic oath of the doctors, who seemed fine, and the rest of the establishment. I canceled the procedure and am now fighting to get the deposit back.

  This place is a waste of time. Charged thousands of dollars for a sleep study that was not even read or signed off by a doctor. I was told I had mild sleep apnea, and they tried to sell me on a couple of overprices mouthpieces. I questioned the study, and the two ladies could not explain it and they seemed very confused and under trained in this field. So I sent the results to my primary physician, and she had me do a consult with Community Health Sleep Medicine. The consult with the doctor said the my sleep study was poor at best and the results were not valid, nor were they reviewed or signed off by a doctor. So I did a sleep study with a mouth piece, chest band, and a finger monitor for oxygen. Test results found, no sleep apnea detected - review and signed off by a Doctor. Advent Knows is a joke. Overpriced Scam. Do not Waste your money or your insurances money!

  They don't deserve 1 star. I had a balloon sinuplasty. I had a nose bleed for 4 days. After 1 year I feel the same. I would strongly suggest you do research before you have this procedure. They ****.

  SCAM SCAM SCAM SCAM SCAM SCAM SCAM!!! I want to make that abundantly clear, so that other people don't suffer the same fate. I had a procedure done (not the one I needed, but the one they told me I needed) - if anything, that procedure made my life worse. I went to an actual ENT doctor, who was able to diagnose my issue in 5 seconds. Advent was atrocious from the start - good luck getting a hold of someone in any office, other than billing - the company knows how to respond when it comes to taking your money. SCAM SCAM SCAM SCAM SCAM SCAM SCAM!!!

  All these reviews are accurate! I went in for a "consult" they asked a few questions and poked around a bit. At no point was cost or coverage mentioned. They set me up for a sleep study and CT scan, which hasn't happened yet. I suddenly received a bill for $1100! That's insane! No way I'm going back there!

  Went in for initial convo, came out with a $700 bill with no information telling me it would be that much, they basically told me it was an intake session and then billed it as an out patient procedure, I didn't even see an actual specialist! On top of that, when I called to ask them why, I got no response and then next thing I know, I got sent to a collections agency. DO NOT recommend, just a big old money grab, wish I had checked the other reviews before I went.

  Thank you for your feedback. We take all reviews to heart and this is no exception. ADVENT is a patient-centric organization that strives to deliver results in an efficient manner for people, which is why medical evaluation and treatment starts at the first visit. In effort of transparency, patient authorization is obtained from before an endoscopy procedure is performed by one of our board-certified Physician Assistants or Nurse Practitioners. Since 2004, we've operated in the best interest of our patients, not our pocketbooks, and are happy to answer any additional questions offline at ************.

  This place is a rip off. My husband had nose surgery to open his airways. What they charge insurance is crazy. His bill was more than when he had his prostate removed. About $50,000. His follow up visits for them to look in his nose and pull out some scabs cost $1800 each visit. He had surgery in December of 2022 and his last visit was January of 2023 and we just we received a bill today May of 2024 for his last visit that wasn’t covered. That was over a year ago. Really get some better billing. Why am I getting a bill over a year later. I had to go look up my eob and saw it was filled in March of 2023. Go someplace else unless you have money to throw out the window

  BEWARE OF YOUR BILLING, particularly if you are on ********* I had a 30 minute consult with only a PA, and two weeks later received a bill that was submitted to my insurance and ******** for $1,095.57, of which $700.39 was for a "nasal endoscopy" THAT WAS NEVER PERFORMED. The office visit alone, again only with a PA was for $395.18. If I had not called to question these charges all would have been paid for false claims submitted to my insurance and ********* I was told they would look into it and would call me back immediately with their findings, of course which they never did. I followed up only to find that they admitted falsely submitting those charges and a correction would be made. I can't comment on their professional medical services as I did not pursue further, but Advent appears to be more of a corporation than a medical service charging extremely high for services that may or may not have been preformed. Let's face it, all that advertising you hear and see has to get paid somehow! Reading through previous reviews overcharging for services not performed seems to be the norm.

  Initial visit/assessment was $1,095.57. My copay helped but the surprise, additional $700 “surgical procedure” was not covered. Read other 1 star reviews and you’ll see the same charges and billing practices! They are not up front about pricing, questionable billing practices, and surprise billing. I was excited to finally get some answers and improve my breathing. They were in-network and their providers were actually recommended when searching through my health network website. The office was clean, front desk personal were nice. I was required to pay an upfront copay, this matched what I was expecting based on my insurance plan, so no surprise or issues there. I thought the PA I worked with was very knowledgeable and thorough, or so I thought. As part of the initial exam I was told they needed to do a nasal endoscopy. Next, I was told a CT was wanted but that insurance won’t cover it until at least two rounds of antibiotics were tried. So antibiotics and nasal sprays were ordered, a CT scan was scheduled for a few months later and I was on my way. About a month later I received a large bill for a surgical procedure. The nasal endoscopy was billed as a separate, surgical procedure and not covered by my insurance. I had no idea this was not part of the initial visit and was being charged separately, let alone as a surgery to my insurance. I can only imagine what the CT or procedure would cost! Initial visit billed at just under $398.18, thankfully only $30 copay Separate surprise surgery billed at $700.39, cost reduced for in-network with **** but $382 billed out of pocket As someone else who works in healthcare, I will do my best to make sure people stay clear of Advent and its providers due to these shady practices.
