A June 30, 2020, my gynecologist sent to Medicare the request for a TSH (84443) and jab (36415) service. Unfortunately and unbeknownst to me, the doctor's office miscoded the TSH lab work. In September, 2020, I began receiving a Lab Corp bill of $119.00 for the before mentioned lab work. In calling their office, I was only told that that Medicare had denied the claim with no further and that I would be sent to their Collections after 7 notices. In December, 2020, I finally paid the $119.00 to Lab Corp. I sent an Appeal to Medicare in mid August, 2020 and called in mid September for an update. I was told to call in mid November for an outcome or I would receive a letter concerning my appeal. In the meantime, I paid Lab Corp. On 1/12/2021 I called Medicare for an update because I had not received any information on my Appeal. Finally a CS person, told me that my original Appeal in 2020 had never been processed. I resent my Appeal mis-code update which was received by Medicare on 1.25.2021. On 3.19.2021, I was told that a positive decision on my Appeal had been made on 3.11.2021. I didn't hear the fact that Lab Corp would be paid $19.80 for my lab services. None of my documents could be attached according to your format needs. So, when I called Lab Corp to make sure that they had received Medicare's positive decision, again, I didn't hear the $19.80 only refund. I received a check from Lab Corp for $19.80 and called CS to see why they didn't refund the full amount I had paid of $119.00. I was told that Lab Corp only refunds the amount that Medicare pays them. What a robbery by Lab Corp. Needless to say, I'm not the only customer they continuously rip off with this "medicare" policy.
