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.
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 team members. 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.
We are specifically looking for candidates with deep experience in post-acute and/or hospital-based prior authorization workflows, along with hands-on Epic experience. Exposure to outpatient specialty care is a strong plus.
As a Prior Authorization Specialist at Ascertain, you will play a critical role in our AI-powered prior authorization solution. You’ll collaborate closely with operations, leadership, and product teams to help shape how prior authorization is transformed through automation and AI.
You’ll partner with healthcare providers—particularly in hospital and post-acute settings—to reduce administrative burden and streamline complex workflows. Day-to-day responsibilities include both manual processing and oversight of automated submissions across services such as procedures, referrals, and medications.

Communicate with hospital teams, post-acute providers, and outpatient specialists to gather required documentation
Submit prior authorization requests to payors using established workflows and Epic-based processes
Monitor and track authorization requests to ensure timely processing and follow-up
Respond to inquiries from providers, patients, and payors regarding authorization status
Maintain accurate and detailed records of submissions, approvals, and denials

Collaborate with internal teams to improve workflows and support automation efforts
Stay current on payor policies, Epic workflows, and industry changes
4+ years of prior authorization experience, including hospital-based and/or post-acute care settings (required)
Hands-on experience working in Epic (required)
Experience across multiple specialties (e.g., oncology, cardiology, rehab, pharmacy, etc.) is a plus
