Wanja Maina

I’m a results-oriented Medical Billing Specialist and Accounts Receivable Specialist with more than 3 years of experience in healthcare administration, revenue cycle management, insurance verification, claims processing, denial management, and patient care coordination. I’m especially proud of how I combine accurate billing execution with clear, respectful communication so patients, payers, and internal teams stay aligned.

In my current accounts receivable role, I manage full-cycle billing and accounts receivable operations, verify insurance eligibility for multiple payers, and handle prior authorization requests and denial appeals using payer portals and supporting documentation workflows. I’ve used EOB and ERA analysis to reduce overall claim denial rates by 40% and implemented structured AR follow-up to reduce AR aging by 35%, while maintaining 100% HIPAA-compliant practices with zero PHI breach incidents.

Previously, as an Insurance Verification, Prior Authorization and Intake Specialist (DME/HME), I supported high-volume inbound and outbound customer service and drove operational consistency by training and onboarding 6 new team members. I maintained strong quality outcomes, earned Employee of the Month recognition for exceptional customer service and operational performance, and focused on continuous improvement through process guides and reusable training materials.
