As a Billing Analyst at Optum from 2022, I was responsible for processing and validating invoices while ensuring accuracy and compliance with company policies. My role involved maintaining and updating financial records, contracts, and rate adjustments, as well as reconciling accounts to resolve billing discrepancies and prevent financial errors. I coordinated with internal teams and clients to address billing concerns and ensure timely payments. Additionally, I generated reports and assisted in audits to maintain data integrity and compliance. I also utilized billing systems and Microsoft Office tools for efficient record-keeping and data management.
