You have been given the correct information by Papa but I want to reinforce that answer.

Look at your explanation of benefits [EOB] from your insurance company for that encounter. I can 100% guarantee you that your treating physician is not familiar with the exact wording of your specific plan, rather only knows in general terms what is covered or not covered.

The 82 could be a copay, a coinsurance, a deductible or a non covered procedure cost. The EOB will detail exactly what you owe for that visit and why you owe it. If you cannot access the EOB online under "claims" or a similar tab, call the carrier and they should tell you over the phone.

Look at all the earlier visits as well. It is possible you owed the 82 from an earlier visit not the one in July and it took time to be processed.

If you are unable to find a reason for the charge after this then you need to contact the office manager for the practice and tell him/her that you have been unable to resolve this with the billing office. Again, your doctor is not the person who knows about charges, copays, deductibles, coinsurance and coverage denials.
