During that time my home sold and I'm moving back to my home state. I kept the follow up appointment but I will continue my care elsewhere. Dr Klein is a sweet caring Physician. I highly recommend him. His staff, depending who you get answering the phone will or can be helpful. Often you're sent to a VM or not answering at all. That happened to me several times. Again I liked Klein a lot.

Absolutely unacceptable billing practices…read more I was overcharged for a preventive screening -- something that is 100% covered by insurance. Not "maybe covered." Not "partially covered." Fully covered. And instead of automatically correcting the overpayment once insurance processed the claim, this office just... keeps the money unless you call and demand it back. Let that sink in. They will not issue refunds automatically. The patient has to catch the mistake and call. How many patients never even realize they were overcharged? How many people assume the office knows what it's doing and trust the bill? This office handles insurance claims every single day. They know how preventive services are billed. They know preventive screenings are covered at 100%. Pretending confusion or acting like this is some unpredictable insurance mystery is insulting. This isn't a rare coding anomaly -- it's routine, standard billing. Patients shouldn't have to audit their own medical bills to make sure a provider isn't sitting on their money. If you overcharge, you fix it. Automatically. Period. If you go here, scrutinize every single bill and compare it to your EOB. Apparently, that's the only way to make sure you're not quietly overpaying.

Mentioned, she was out of the office and that there could be another doctor that could see me so then I had the practice manager Victoria Herget call me and I was telling her how this doctor yells at patients in the appointments says that they're questions about their own medical stuff should not be asked in the appointment that that's not what it's for and so the practice manager Victoria Herget said that her yelling at me was just Dr bortuzzo HOT ITALIAN WAY OF SPEAKING so basically saying at that facility it's ok that patients get yelled at and blamed for the doctors or even assistance negligents so I would say , if you're going to see Dr bortuzzo or even going to this facility, you should record all interactions.Especially when practice managers call you too cause that's what I did and then I got a phone call saying they don't take my insurance anymore

Well guess what, I went to another G.I. got some blood tests, CT scan, and it was something bigger. If you want someone who will miss something, go to this doc. If you want someone who will listen to you, advocate for you, go to any other doctor. I only took this appointment because it was the first one available, I'd recommend anyone to wait for another doctor, even if it's another one in the same clinic. This was the first doctor that I actually left in tears. Do not waste your time.

The office staff communicated well. The person at the front desk, Megan (?) probably should be in another position. She sounds and acts like a robot. However, in short, it's exceedingly clear that the joint practices of Drs. McCallum, McNerney and Hanna have LONG ago outgrown the facility. The parking lot is too tight and stretched to the limit. On the day of a procedure, whether the patient or driver, this adds up to additional stress. The larger waiting room needs better lighting and some freshening up in the area of esthetics. The smaller surgery waiting room, to the east, is an abomination! The day that I was there, it was pretty chilly outside. The patient exit door opens frequently, and it got cold and drafty. So, there we are, faithful spouses, drivers and patients--people who may not have eaten in more than 24 hours and slept little--sitting in this ugly, cold an cramped waiting area. There aren't enough seats and there isn't enough room for comfort. The patient exit door should be in the back of the building with a dedicated door for such and a safe place where their drivers can park. As the throughput of the facility is high, I have to say that I felt rushed as I was coming out of anesthesia. Rushed, in that beds are in very short supply. "Wake up and get out of here!" So, to the owners of the business, I say, take some of your retained earnings, and invest in a better property and plant whereby your patients can receive the first class treatment that they deserve and that you want them to have.
