I am now scheduled for a 5 year re-exam. Scheduling was a little bit of a problem in that the telephone number given in the email notification goes to an automated system that switches to voice mail after an extended wait on hold. Calls were not returned, so I had to contact Dr Dewar's office at the number I had from a previous visit.

He takes his time, answers your questions, and can make you smile! He's performed many colonoscopies and endoscopies on me and even referred me to a great surgeon the times it was required. I do wish it was easier getting a quick appointment sometimes but I think the people up front do their best to work you in where and when they can. His nurse Nina is also very nice and informative, if I get her voicemail she's always prompt to call me back. Overall, if you need a gastro Dr, he's the man to see! Big thumbs way up for Dr. Dewar!

I was called by their scheduling person (Eli) but did not get the message till after they had closed for the weekend. I literally called everyday for a week trying to schedule an appointment and never received a return call.

On a side note I called my personal doctor back and explained what I'd gone thru and was told I could try TDDC Southlake Office.

This is, without question, one of the most unprofessional and frustrating medical offices I have…read moreever encountered. The overwhelming impression is that their priority is maximizing billing rather than providing accurate, ethical patient care. Even the office setting--located in a converted old Wendy's building--reflects a lack of professionalism. I was referred by my primary care physician for a colonoscopy at a five-year interval due to my documented high risk for colon cancer, based on both a personal history of polyps and family history. This office has my medical records clearly indicating that I qualify for high-risk surveillance. Despite this, they are refusing to bill the procedure correctly. Instead of coding it as "high-risk surveillance," which my insurance has explicitly confirmed would be covered at 100%, they are insisting on labeling it as a "routine colonoscopy" and demanding $800 upfront. What is especially concerning is that they acknowledge my history of polyps, yet still refuse to use the correct billing classification. This is not a gray area--it is a clear misrepresentation of the medical necessity of the procedure. Attempts to resolve this have been met with complete dysfunction. I have been repeatedly bounced between the Billing and Scheduling departments, each refusing to take responsibility and directing me back to the other. At no point has anyone taken ownership of correcting what is clearly a billing and coding error. I have already confirmed with my insurance company that the procedure would be fully covered if billed correctly. The office's continued refusal to do so raises serious concerns about their billing practices and their commitment to ethical standards. At this point, this is no longer just an inconvenience--it is a failure to provide appropriate patient care and accurate billing. I would strongly caution others to verify coding and billing practices in advance before trusting this office with their care.
