<prompt> Human: I will try to make this as concise a possible. Thank you for taking the time to read my frustrating saga.Spring 2010: I visit a doctor for a physical.Fall 2010: I move across country and change my insurance. I update my address, retain my email and cell number, and verbally verify there is no balance with the doctor because the visit was my free annual physical. Its been over four months and I have received no statement regarding the visit. A week later: I incur a balance. The claim is filed days before the insurance companys deadline. The visit is incorrectly coded, and my insurance company denies the claim. For four years, I have no knowledge of this balance despite retaining my same cell number, email address and checking my credit report.September 2014: I discover my impeccable credit is blemished by the unpaid balance and has been sent to a collection agency. Im confused because I had coverage and the visit should have been my free annual physical.April 2015: After months of unearthing why I have an unpaid balance and appealing to the doctors office and insurance company, I give up, and pay the balance to the doctors office. The balance is has now a over hundred dollars more than it was in September 2014 because of added recovery fees.May 2015: I receive a notice from the collection agency for the 275. I call the doctor to question this and verify my balance is zero. I am informed they just havent gotten around to contacting the collection agency to tell them its been paid. I contact the collection agency and inform them the bill has been paid.Today: I receive a bill from the doctor for more recovery fees. My questions:Is there any recourse I can take? This seems highly unethical. How many more bills for recovery fees should I expect? If it matters, I included a letter stating this is my final payment regarding this balance.EDIT for format and additional comment: I just wanted to add my appreciation for everyones thoughtful response. Ive always had excellent credit and this experience has been beyond frustrating.  <response>: This happened to me and took over 10 months to get the Dr.s office to fix. I tried for months to get the charge removed by speaking with the office, the billing vendor and the insurance company. I visited the office for my free annual physical and ended up with a charge for the free visit, a breast exam and an additional outpatient visit fee because the office said they had to provide me two separate diagnoses for my issues! Nothing was wrong with me. I wasnt sick, wounded or complaining of any ailments. I never saw the doctor and the nurse practitioner simply talked to me. She never touched me, took blood or examined me in any way.I called the insurance company to report fraud and they said they couldnt do anything. They said it came down to the doctors word versus mine.I went on Yelp and posted a complaint. The doctor responded and essentially said I was too stupid and plebeian to understand insurance. I responded again. I work in healthcare and am fully aware of the procedures I had. They continued to send bills and threatened my credit so I finally drove to the office and told them I was going to sit there until we figured this out. I had them print out my medical records which clearly showed they were lying and miscoding my exam. I dont know if it helped to physically stand in front of them and accuse them of lying, but the bills seem to have stopped. I also agree with the other poster that said to just start posting reviews any where you can. I would post them and then send the office screen shots so theyre aware of what youre doing. Let them know you will post reviews on every healthcare site that allows them and file reports with any agency that accepts them. Yelp, ZocDoc, Healthgrades, Google reviews, etc. Good luck!!
