I was scheduled for an endoscopy at 2pm. When you schedule your appointment, you are not told that you should arrive 45 minutes before your actual scheduled appointment. This is counterintuitive, however can be considered patient error. I arrived around 1:45 thinking I was early for my appointment but received a call at that time telling me that I was late for my procedure. I never received a call the day of, nor a message at 1:15 when I was expected to be there. I was told that if I arrived before 2 pm (my appointment time) that the doctor could still do the procedure today. I agreed and quickly filled out the paperwork. When everything was submitted, I was pulled out into the hall by one of the front desk associates and told that the doctor had two separate procedures and would not be able to complete my procedure today. After a bit of back and forth the front desk associate inquired whether I had forgotten my appointment was today or if I was running late. Long story short, this felt like an unnecessary interaction and circumstance that could have been avoided had there been better communication. While doctors and office administrators have busy schedules, so do patients. I wasn’t even asked when I might be able to come back for a procedure or even get a chance to speak with my doctor. An unfortunate occurrence but hopefully can spare others from having the same experience from lack of clarity.
