Receptionist selling medical tests

Location: Austin, Texas

I visited a doctor for the first time, with no recommendation happening during the visit until the receptionist asked something like "do you wanna go ahead with that allergy test?" Thinking I must have missed the doctor recommending this, I signed up for it, later paying $300 for something I realized had nothing to do with my visit.

I recently had my follow-up, and asked the doctor about this, thinking that he recommended the test and wasted my money. He said he didn't give the recommendation, that's just something the receptionists are told to do, and that they would ask me today if I wanted an "advanced physical" regardless of him recommending it. He was insistent that it was out of his control and simply "what the receptionists were told to do."

After a cursory Google, I am convinced that this is fraud, and I wanted to come here to ask about what options one may have for pursuing legal action against this company. Is small claims suitable for this? Is there some sort of institution I can report this to?
