<prompt> Human: For the original post, click hereHi Reddit,Quick Summary Of Original PostI Canadian visited friends in NYC to celebrate the completion of my cancer treatment, and in a beautiful twist of irony, I woke up with acute chest pain and shortness of breath which were likely side-effects of cancer treatment, so I went to the ER. I was diagnosed with bilateral segmental pulmonary emboli multiple blood clots in the lungs and pericarditis inflammation in the heart, and they started me on prednisone for the pericarditis and lovenox for the blood clots. After undergoing various examinations for 5 hours, I left the hospital and received a 15,000 medical bill, and flew back to Canada for treatment.The Recovery Once I arrived in Canada, I went straight to the hospital and spent 3D2N there. Since I only had the NYC medical notes not the actual tests from the CT Scan, blood tests, or xrays, there was no way for the doctors to definitively confirmcontradict the NYC diagnoses. They ran a few blood tests including a D-Dimer, an x-ray, and ECGs, but unfortunately, the results told them nothing bc the NYC incident had already occurred. I was feeling better, and rather than run another CT Scan, they just assumed the NYC diagnoses was correct because it was administered by a reputable hospital. They gave the rest of my prednisone for the pericarditis and started me on apixaban to replace the lovenox for the blood clots.After I finished the prednisone treatment still taking the apixaban, I was still experiencing chest pain and breathing difficulty, so I spent the following 3 months visiting various specialists to figure out what the fuck happened to me and why it wasnt going away. The uncertainty and differing opinions were extremely draining.Two key events in my recovery:- Armed with my CT scan results from the NYC hospital took me about a month to get, I went to a Thrombosis clinic to investigate the pulmonary emboli diagnosis. They repeated what every other doctor said, Firstly, after reviewing your medical notes, we believe your NYC diagnosis of pulmonary emobli is correct because it was administered by a reputable hospital. Then they continued, Normally we would continue your apixaban treatment, but since you underwent chemotherapy within the previous 6 months, we need to start you on a regular dose of heparin which is a shot. I responded, You dont even know for sure if I have blood clots! How are you going to continue my treatment without first making sure?! After a fair bit of pushback, I finally convinced them to check the NYC CT scan, and it turned out that I never had pulmonary emboli!!! The NYC diagnosis was incorrect. They were trying to find any reason to avoid analyzing the CT scan themselves, and it turns out the diagnosis was wrong! Whatever, it was very unprofessional, but at least I got off of the blood thinners and got a little bit closer to figuring out what the hell caused the NYC incident.- I went to see a cardiologist, and he suspected that I the cause was pericarditis all along. To deal with my continued chest pain and breathing difficulty, he started me on colchicine to reduce inflammation in my lungs. After about 3.5 months, I finally recovered. Im still not exactly sure what happened to me, but after hearing opinions from at least 9 different specialists, it was likely pericarditis caused by the radiation treatment.The Medical BillI was completely freaked out because my case was in a bit of a grey area. The rule is that your health must be stable for 3 months prior to your travel in order to be covered. Since I had undergone chemotherapy and radiation treatment within 3 months prior to my trip, there was room for my insurance company to claim that my health was unstable. On top of that, it took the hospital months to send me an itemized bill in the mail. Until that point, they told me the bill was 15,000, and that my insurance was only willing to pay 135. However, when I finally got the bill in the mail, it was actually 21,500!!! Summary of the bill:- CT Scan: 5,126- Emergency Room: 4,609- Laboratory: 1,807- Semi Private Room: 7,265- Pharmacy: 15- Radiology: 530- Nuclear Med: 69- Ambulatory Surg: 496- Doctor Services: 1,583I submitted the claim, a couple of doctor notes confirming that they gave me permission to travel, and evidence that I was misdiagnosed to my travel insurance company. I didnt hear from them for months. Then I received a letter in the mail today that my insurance is covering the entire bill!! What a relief! A huge weight has been lifted off my shoulders. Im healthy for now, at least, and I can finally put this mess behind me.Thanks for listening!TL;DR After seeing several specialists in Canada, I discovered that I was misdiagnosed with pulmonary emboli by the hospital in NYC. It is impossible to know for sure, but I was likely suffering from pericarditis. My medical bill turned out to be 21,500, and my insurance covered 100 of the bill.  <response>: Congratulations! Just goes to show that if you take the necessary steps beforehand and stick to your guns afterwards, you should be in the clear.In a similar vein, I called my doctors office about a whopping 15 bill they sent me for something I had already paid. It took a 5-minute phone call to get that sucker taken off my account. Yay for us and getting rid of unnecessary medical bills!
