What I'm looking for

I’m seeking remote prior authorization work supporting U.S. healthcare providers, and I’m available to work U.S. Central Time hours.

At PHARMBILLS, I manage end-to-end skilled, custodial, and retro prior authorizations for a Centers Health Care account. I process 25–35 cases a day through Waystar and Availity, with 95% approved before the service date.

I gather clinical documentation from care teams and payer representatives, helping secure approvals in an average of 1.5 days. I also track authorization statuses and renewal dates in Excel while maintaining HIPAA-compliant records.

Previously, I posted insurance and patient payments for a CBS account at PHARMBILLS, coordinated shipments at LEAN STAFFING SOLUTIONS (CLIENT: INTEGRITY), and supported UnitedHealthcare members. I’m bilingual in English and Spanish, HIPAA-certified, and available for U.S. Central Time hours.
