<prompt> Human: In January, I was sick - fever, cough, etc and went to Little Clinic on a Wednesday. I saw a nurse practitioner and she diagnosed me with sinusitis and gave me a z-pack. During our time she said that my lungs sounded good. I took a pill that evening and the next evening. During that time, my fever never broke and my illness became worse. The next morning Friday I went to our local urgent care, I had a fever still and five minutes with the doc and she diagnosed me with pneumonia. She prescribed a breathing treatment and levoquin sp?, which is a very strong antibiotic. After taking the first antibiotic and breathing treatment, my fever finally broke. Next day I felt so, so much better. Clearly the Little Clinic mis-diagnosed me. When we got the bill, we were irritated. We called twice and they reviewed and evaluated the situation, twice. Both times they said that we still had to pay. Finally spoke to a regional director and she told me the following: she would agree with her NP over a doctor any day and that z-pack will treat pneumonia. Two doctors - urgent care and my pcp told me that z pack will absolutely not treat pneumonia this was relayed to the director. The regional director also argued if I even had pneumonia - two doctors - urgent care diagnosis wo xray and my pcp xray after the fact, with with a lung nodule that indicated pneumonia diagnosed me with pneumonia. So, this whole thing ended with me extremely irritated with them. So, my question. I am really irritated esp since speaking with the regional director. I do not want to pay - its only 30 but its the principle of the thing now. I have excellent credit and do not want to hurt it over 30. Does anyone have any suggestions? Do you know if Little Clinic has a collection agency and if that agency will report to my credit?  <response>: Yeah, so, as a doc, let me just say that azithromycin and Levofloxacin both can treat community acquired pneumonia and there is statistically probably not much difference between how long they take to work. Now your NP may have missed the pneumonia, however, its possible that your pneumonia was not that obvious. Pneumonia can change very quickly over time. So, you should just go ahead and pay the 30.
