1. An audiologist is not a doctor, and doesn't write prescriptions. They test your hearing and try to sell hearing aids. (An optometrist is not a doctor either. They test your vision and give you the results, go where you want. The results of you not following up on those tests won't affect your health unless, say, you fall into a hole you didn't see, or not hear that train coming as you crossed the tracks.)(You don't get a hearing aid or eye glass "prescription" filled at a pharmacy.)
2. Take those hearing test results anywhere you want that sells hearing aids.
I went to the audiologist at my ENT doc's practice. She recommended 4-6k dollar hearing aids. I took the results, not a prescription, to a Sam's Club here in Amarillo. The guy there read the results, tested a few more frequencies, and I bought hearing aids for 12 hundred bucks.
The Sam's I went to has had hearing aids and tests since it opened.
I lost one though. 200 bucks to replace. Going tomorrow. All my info is on his computer, should take about ten minutes.
