About us

Why Centerline.

Centerline Medical Billing was founded in 2018 by behavioral healthcare leaders who recognized that providers needed more than just a billing company. They needed a revenue growth partner.

Long before Centerline was founded, our founders spent decades leading behavioral healthcare organizations, with industry experience dating back to 1998. That experience gave us firsthand insight into the operational and financial challenges providers face every day, from navigating complex payer requirements and utilization management to improving cash flow and scaling operations.

We built Centerline to be the revenue growth partner we believe behavioral healthcare providers deserve. That philosophy continues to guide everything we do.

Leadership That Knows Your Business

Centerline is led by founders Patrick Mahoney, CEO, and Gabe Hynes, COO, alongside an experienced leadership team specializing exclusively in behavioral healthcare revenue cycle management.

Our leadership remains actively involved with every client relationship, because we believe strong partnerships are built on consistency, accessibility and trust. When you have a question, you'll speak with someone you know, someone who knows your organization, understands your goals and has earned your trust. Not a call center or a ticketing system.

Our Approach

We believe the strongest client relationships are built on partnership, transparency and accountability. That's why we work as an extension of your leadership team, providing strategic guidance, proactive communication and experienced support as your organization grows.

We don't believe in one-size-fits-all solutions. Every organization has different goals, payer relationships, operational challenges and opportunities for growth. Our role is to understand your business, align with your objectives, and build revenue systems that support long-term financial performance.

Our commitment is simple: to help behavioral healthcare providers build stronger revenue systems that support sustainable growth, allowing leadership teams to focus on what matters most: delivering exceptional patient care.

Behavioral Healthcare Is What We Know

We understand how behavioral healthcare payers operate, what they require, and where issues arise throughout the revenue cycle:

  • Payer complexity. We know how to navigate payer requirements from benefit verification through final reimbursement.
  • Authorization strategy. We anticipate payer requirements and manage initial and continued-stay authorization throughout treatment.
  • Denial prevention. Our upstream processes prevent many denials before they happen. When one does, we act quickly to resolve it and pursue the reimbursement.
  • Benefits and reimbursement intelligence. VOBs don't always tell the whole story. We combine historical payer data with a deep understanding of each partner's ideal patient and payer profile to provide real-time reimbursement guidance and help admissions teams make confident decisions.

The People Behind the Work

Our team is U.S.-based: no offshore call center and no rotating cast of juniors. The same people who learned your facility, your payers, and your revenue cycle last year are still by your side today. You'll know the people on your team, and they'll be there when you need them.
