Healthcare Administrative Specialist

About the Role

We're looking for professionals with deep, hands-on experience in the administrative and operational work that keeps healthcare organizations running — the "back office" of a medical practice, hospital, or health plan. This spans the full administrative lifecycle: getting patients registered and covered, securing authorizations, moving claims through to payment, managing provider and payer relationships, and keeping records and compliance in order. You'll help us understand the precise steps these workflows take in the real tools you use every day.

Core Workflows (you should actively own one or more)

• Patient Access & Front-End: registration, scheduling, insurance/eligibility verification, benefits interpretation, intake, and referral management

• Prior Authorizations & Utilization Support: initiating, submitting, and tracking authorizations through payer portals

• Claims & Revenue Cycle: claim submission, status tracking, denials and appeals, A/R follow-up, and resolution of rejections

• Remittance & Payment Posting: electronic remittance advice (ERA), payment posting, and reconciliation against clinical charges

• Provider & Payer Operations: credentialing, provider enrollment, payer configuration, appeals & grievances, and member/provider services

• Health Information & Practice Administration: medical records administration, release of information, and day-to-day practice/office operations

Requirements

• 3+ years of daily, hands-on experience in a healthcare administrative / back-office role

• Direct experience with the systems this work runs on — payer portals (Availity, Optum/Change Healthcare, Waystar, Office Ally, or individual payer hubs like UHC Link, BCBS, Aetna), EHR / practice-management platforms, and/or clearinghouses

• Currently working in a healthcare administrative role

• Based in the United States
