Richard Cartajenas

I work in U.S. healthcare ancillary services and Revenue Cycle Management (RCM), where I coordinate with vendors, validate billing inputs, and keep payments accurate and on time. I bring strong attention to detail and analytical accuracy to high-volume workflows.

At ISTASolutions, I processed and reviewed invoices for U.S. healthcare ancillary service providers, collected and validated vendor invoices for long-term care facilities, and resolved payment discrepancies through email and phone follow-ups. I also maintained accurate vendor/patient accounts by performing account reconciliations and investigating outstanding balances while following ePHI and HIPAA Compliance requirements.

I support Medicare-focused processes by assisting with insurance verification and validating patient billing information when required. I reviewed discharge and ancillary billing records to support accurate reimbursement and verified ambulance point-to-point transport using mapping tools to ensure Medicare compliance.

I consistently met productivity, quality, and compliance standards while handling confidential financial and healthcare information. I adapt quickly to various tools and systems, and I use AI and productivity platforms to stay efficient and reliable in day-to-day operations.
