Mark Jester Wagan

I am a detail-oriented professional with over four years of experience in high-volume, accuracy-sensitive data environments, specifically within the healthcare and customer support sectors. My career has been defined by a commitment to operational excellence and a rigorous "auditor mindset," ensuring that every piece of information processed meets the highest standards of integrity. In the complex field of medical billing, I leverage my deep understanding of member benefits, insurance verification, and regulatory compliance to ensure seamless financial workflows.

During my tenure at Optum, I served as a Service Support and Customer Care Professional, where I was responsible for reviewing and validating member benefits and insurance information during live interactions. This role required navigating multiple complex client protocols and internal systems while maintaining strict HIPAA-compliant documentation. I successfully managed high-volume case queues, ensuring the timely and accurate transition of sensitive data between CRM platforms and internal systems. This experience honed my ability to handle confidential medical data with the utmost discretion and precision.

My background also includes significant roles at VXI Global Solutions, Concentrix, and Teleperformance, where I refined my skills in billing adjustments, account documentation, and financial record management. I have a proven track record of maintaining 99%+ data accuracy, a critical metric when preventing billing discrepancies and ensuring service eligibility. My technical proficiency spans Microsoft Excel, Salesforce, and various CRM platforms, allowing me to reconcile data across systems efficiently.

Beyond technical skills, I excel in high-pressure environments that demand strict adherence to deadlines, such as end-of-month reporting and real-time data validation. Whether I am cross-checking encoded information or managing structured digital documentation, my goal is always to prevent errors before they impact the bottom line. I am a proactive problem-solver who thrives on the challenge of multi-protocol account navigation and context switching. I am now eager to bring my expertise in data integrity, compliance, and workflow management to a dedicated Medical Billing team where I can contribute to the financial health and operational efficiency of the organization.
