The Leader in U.S.-Based Prior Authorization Solutions

An Extension of Your Business Office

Founded in 2015, NYX Health supports healthcare organizations across the full patient and payment lifecycle—from hospitals and health systems to physician practices and specialty providers.

We manage key revenue cycle functions including prior authorizations, insurance verification, scheduling, denial follow-up, clinical documentation improvement (CDI), and Independent Dispute Resolution (IDR) services. Our U.S.-based teams work directly in your existing systems to help reduce delays, prevent denials, and optimize financial performance.

With 98% prior authorization accuracy and the ability to scale quickly, we help organizations stay ahead of volume and payer demands without adding internal strain.

We don’t replace your business office—we become an extension of it when extra support is needed.

Why Prior Authorization Matters to the Revenue Cycle

When prior authorizations are delayed, inaccurate, or incomplete, the impact extends far beyond the front end. Missed or incorrect authorizations lead to preventable denials, delayed reimbursement, and increased administrative burden across the revenue cycle.

By improving prior authorization performance early on, healthcare organizations can reduce downstream issues and accelerate cash flow.

Why Outsource Revenue Cycle Management?

Revenue cycle work has become harder to staff, manage, and scale. Regulatory changes, payer inconsistencies, and rising denial volumes have made it difficult for internal teams to keep pace, especially without adding cost.

NYX Health helps providers stabilize and strengthen revenue cycle operations by combining AI-driven automation with experienced clinical and revenue cycle professionals. We work inside your EHR to support patient access, clean claims, and proactive denial management—reducing delays, write-offs, and unnecessary rework.

Our clients partner with us when they need:

  • Relief from staffing gaps or volume spikes
  • Faster resolution of denials and underpayments
  • More predictable cash flow
  • Support that adapts as payer rules change

NYX Health isn’t just outsourced RCM. We’re a performance partner focused on keeping revenue moving without adding internal burden.
