At Scale, Small Leaks Become Big Numbers.

Managing dozens of providers across multiple specialties means that even a tiny denial rate on your dashboard quietly turns into a serious monthly revenue leak. The problem is rarely a lack of effort from your team. It is almost always a structural flaw. You cannot fix a broken system just by adding more staff to chase claims inside payer portals.

The real solution is building a better foundation. You need one unified workflow for every single provider. You need coding that is strictly accurate to each specialty across the entire group. And you need reporting that your administrators can actually trust to make strategic decisions. When you bring your denial rate down by just a few points at your volume, the return is massive. We are talking about recovering six figures a year, not just fixing a rounding error.

Large Practice Billing Requires Specialized Enterprise Expertise

Group practice billing operates under a completely different framework than solo provider or single-specialty billing. When you scale to dozens of providers, a minor compliance error or misassigned claim can trigger costly audits and severe revenue leakage. Our revenue cycle team protects your reimbursement across every provider and location while ensuring strict adherence to complex payer rules.

Accurate rendering and billing provider assignment across all locations.

Correct NPI validation to reduce claim rejections.

Compliant shared and split visit billing for proper reimbursement.

Proactive credentialing and payer enrollment monitoring.

Accurate place of service validation to support compliant reimbursement.

What Our Clients Say About Us

Healthcare providers across the country rely on OneMed Billing to manage their revenue cycle with accuracy, consistency, and specialty-specific expertise. Here is what some of them have to say.

Testimonials

“We were losing $180,000 annually to credentialing lapses, underpayments, and inconsistent coding. OneMed implemented enterprise-level controls that eliminated these leaks. Days in A/R dropped from 58 to 34, and we added five locations without hiring additional billing staff.”

COO, Independent Multi-Specialty Practice (32 Providers)

“Our professional and facility billing were disconnected, creating compliance risks and revenue leakage. OneMed unified operations across seventeen providers and six service lines. Our net collection rate jumped from 91 percent to 97.8 percent with full enterprise visibility.”

Chief Financial Officer, Hospital-Affiliated Physician Enterprise

“Managing billing across four providers and two locations was creating gaps we were not equipped to handle in-house. OneMed gave us one team that handles everything across the group and our A/R tightened in a way that is visible on our monthly reports.”
