Prior Authorization Assistant -… at Ascertain

Meet Ascertain

Ascertain is building AI agents to automate the administrative work that burdens care teams. We are in major health systems and large specialty groups, saving hundreds of staff hours every week.

Our backers include Northwell Health, New York’s largest health system, and Deerfield Management, a leading healthcare investment firm.

Together, we’re on a mission to restore time, trust, and focus to the people who keep healthcare running. Our work is urgent — not because of startup timelines, but because our customers rely on us to drive financial resilience and operational clarity in a system under strain.

About the Job

This is a hands-on role for someone who thrives in high-volume operational environments and is comfortable balancing individual contribution with team support.

You will continue to process prior authorizations directly, often at high volume, while also serving as a go-to resource for other Ascertain Assistants. Over time, this role will evolve into a hybrid operations + technology position as workflows become increasingly automated and integrated with Ascertain’s platform.

This is not a traditional healthcare shift-based desk role. It is an outcome-driven position that rewards ownership, judgment, and follow-through.

What You’ll Do

As a Prior Authorization Assistant at Ascertain, you will play a critical role in our new AI-powered prior authorization solution. You’ll collaborate directly with Ascertain leadership and product teams, helping to shape how prior authorization is transformed through recent advances in artificial intelligence. This is a unique opportunity to work at the intersection of healthcare operations and cutting-edge technology.

You’ll work closely with radiology practices and imaging centers to reduce administrative burden and streamline complex workflows. Day to day, this includes manually processing authorizations and overseeing automated submissions for advanced imaging (MRI, CT, PET, nuclear medicine), diagnostic and interventional radiology procedures, and related referrals. The role offers broad exposure to multiple specialties, external stakeholders, and departments across Ascertain.
