When I worked for the eye doctor doing insurance billing, the allowed amount had more to do with the doctor's office than it did the patient. Some insurance companies have certain amounts set for different diagnosis and procedure codes that the doctors are allowed to bill. For example, when we filed a BCBS claim, we would file for the eye exam and refraction. The exam was $65 and the refraction was $15. When BCBS paid the doctor, they would pay only the allowed amount for those two procedures. I believe they paid $40 for the eye exam, and $10 for the refraction. We weren't allowed to charge the patient for the difference. So the allowed amount is what the insurance company has agreed that the doctor will be paid for specific procedures filed to them. Another important factor is your diagnosis code. As long as everything is normal, nothing to worry about, but some diagnosis codes can change the type of procedure. Sometimes patients would come in for a check-up and it turned out they had glaucoma, or something. That means the diagnosis code for glaucoma gets tacked onto the procedure, and it becomes a medical necessity. Anyways, you weren't asking about all that. Sorry.
Hope this is helpful.... If I didn't explain it well, and you are just more confused than ever, send me a message, and I will try again.
