The trusted compliance and revenue-cycle partner for clinical research sites.

Why Hay Hill Advisors


We are the only partner that pairs audit-ready compliance expertise with pioneering revenue-cycle innovation — empowering research sites to capture every dollar while staying fully protected.

The Standard Starts Here

We created the Coverage Analysis — the methodology that became the industry standard for research-billing compliance. That foundation informs everything we build, and every client we serve.

Compliance and Finance, Unified

Our integrated model bridges research billing compliance and revenue cycle management — eliminating the fragmentation that creates risk, delays time to activation, and leaves money on the table.

Research Payment Analysis

Insurance coverage doesn't guarantee payment. Our proprietary Research Payment Analysis — built on deep Medicare payment expertise — exposes reimbursement gaps before they become budget shortfalls, giving your team projections they can actually rely on.

Revenue Recovery & Claims Management

We ensure every billable service is captured and compliant, then pursue full recovery of sponsor payments owed to your institution. Our claims review process closes the gap between what was agreed to and what was actually paid.

Training That Builds Lasting Capability

Our training and education programs equip your compliance, billing, and research teams with the knowledge to sustain best practices and operate with confidence at every level of your organization.

Your Institution's Advocate

We work exclusively for research sites, never sponsors. Every analysis, recommendation, and strategy is designed to strengthen your compliance posture and financial position.

Our Mission


We apply the regulatory expertise and payment methodology we pioneered to empower research sites — mitigating risk, leveling the playing field with commercial sponsors, and aligning operations to ensure every dollar is captured.
