I resolve complex claims, denials, appeals, and healthcare billing discrepancies.

Message

I've spent more than 10 years resolving claims, appeals, denials, and billing issues across long-term care, disability benefits, and healthcare operations.

At Mutual of Omaha, I processed appeals and rendered denial determinations for long-term care claims, reviewing medical and functional documentation against policy provisions, eligibility criteria, and regulatory requirements. I managed a high-volume caseload across multiple systems while identifying documentation trends that improved review workflows.

In my current contract role with Healthcare Management Source, I perform medical billing and ICD-10 coding, resolve discrepancies before claim submission, and protect patient information under HIPAA. Earlier roles at Health First strengthened my experience in benefits eligibility, enrollment, provider communication, and appeals.

I've also supported financial operations at Ana Luisa and United Nations Federal Credit Union through accounts payable, receivable, payroll, payment processing, and reconciliation. I'm bilingual in English and Spanish and bring a detail-focused approach to accurate, compliant operations.
