What I'm looking for

I seek a role in medical billing or healthcare administration where I can improve billing accuracy, optimize financial processes, and support timely claims/reconciliations.

I am a medical billing and HMO billing officer with hands-on experience processing claims, reconciling denied claims, and managing billing workflows for Health Maintenance Organizations. I combine formal education in microbiology with targeted training in medical coding, billing, and virtual assistant skills.

In previous roles I streamlined rebate and commission payment processes, supported expense management and invoice tracking, and performed patient data entry and records organization to improve operational efficiency. I have completed courses covering ICD overview, HIPAA compliance, reimbursement guidelines, and practical tools like Google Workspace and MS Office.

I am committed to accurate, timely payable functions and financial process optimization, and I bring strong communication, organization, and project coordination skills to support healthcare administrative and billing operations.
