In the US healthcare system, I started as a collections representative for a hospital for more than a year. I was responsible in following up denied and/or unpaid claims with insurances from California and Texas. I also had an experience with reading and converting EOBs in the system. After this, I moved to a new company where in I started as a claims analyst with the same responsibilities. I've added experiences with contacting patients regarding COB issues and making appeal letters. With the same company, I worked my way from being an analyst, a quality analyst then finally being a supervisor. I had experiences with hospital and professional billing, so I am familiar with UB04s and CMS-1500s. 3 years after, I decided to apply as a medical biller in the virtual assistant world wherein I had experiences with making sure patients' insurance information are up to date, billing CCMs, and correcting information for denied or rejected claims. I also had experiences with working as an office administration wherein I helped out with reports and excel sheets that consist of patient data. I am proficient in various healthcare systems and tools including ACE, Meditech, Epic, Allscripts, Practice Fusion, and CollaborateMD, along with strong skills in Microsoft Excel and Google Sheets. My experience has helped me develop keen attention to detail, strong analytical skills, and the ability to meet performance targets in fast-paced environments.
