Mark Lester Antonio

I am a Registered Nurse with over 8 years of experience in the BPO healthcare industry and more than a year of hands-on hospital experience. I specialize in prior authorization, utilization review, and payer credentialing, with strong knowledge of healthcare processes, insurance guidelines, and compliance standards.

Throughout my career, I have developed strong analytical, communication, and problem-solving skills, allowing me to efficiently manage authorizations, coordinate with providers and insurance companies, and ensure timely and accurate case handling. I am experienced in using platforms such as CAQH, PECOS, MD Staff, and various payer portals.

I am detail-oriented, adaptable, and committed to delivering high-quality results while maintaining patient-centered care and operational efficiency. I thrive in fast-paced environments and work well both independently and as part of a team.
