Top Medical Billing Companies in New York: 2026 Comparison Guide

Choosing a medical billing partner is one of the highest-leverage decisions a New York practice makes each year. Get it right, and claims move cleanly through a payer landscape that includes commercial insurers, Medicaid Managed Care Organizations, No-Fault, and Workers’ Compensation. Get it wrong, and revenue quietly leaks out through denials, aging receivables, and coding errors that never get caught.

This guide compares AffinityCore against nine other established medical billing companies serving New York practices, using publicly available information: independent review platforms (BBB, Trustpilot, Google, Yelp), company-published specialties and track records, and the criteria outlined in our methodology below.

A note on transparency: This guide is published by AffinityCore. We’ve listed ourselves first because, naturally, we believe in what we offer but every claim about AffinityCore below is something we can stand behind, and every claim about the other nine companies is sourced from their own public listings, review platforms, or company sites, cited where possible. Where we could not independently verify a rating for a company, we’ve said so rather than guessed.

How We Selected These Companies

Companies included in this guide were selected based on:

• Active presence serving New York healthcare practices, either headquartered in New York or with documented New York client experience
• Public visibility, meaning the company has a findable BBB, Trustpilot, Google, Yelp, or Clutch profile, or a substantial published track record
• Range of practice sizes served, from solo practices to multi-location groups, so this guide is useful across different practice types
• Service breadth, covering companies offering full-cycle billing, coding, and revenue cycle management rather than single-task vendors

Ratings shown are pulled directly from the independent platform noted next to each one. Self-reported statistics (like clean claim percentages a company publishes about itself) are labeled as such and are not treated as independently verified.

Ratings currently reflect information available at time of writing and are subject to change. We recommend verifying current ratings directly on each platform before making a decision.

A Closer Look at Each Company

AffinityCore takes a full-cycle approach: medical billing, medical coding, credentialing, denial management, and AR recovery are handled by one coordinated team rather than separate vendors. We’re newer to public review platforms than some names on this list, so rather than ask you to take our word for it, we’d encourage you to read our client testimonials directly and request a free revenue analysis to see our approach firsthand.

Credex Healthcare, based in Jacksonville, FL, has built a strong reputation specifically around credentialing and payer enrollment, with RCM services layered on top. Its Trustpilot score (4.0/5 from 15 reviews) and BBB accreditation are independently verifiable.

AnnexMed brings nearly two decades of RCM experience and has been named to Becker’s Hospital Review’s list of RCM companies to know. Its performance statistics are self-published, so ask for independently verifiable references if these numbers matter to your decision.

Core Med Billing Inc. is a smaller, boutique operation well suited to solo providers, with a genuinely strong independent footprint: BBB A rating and a 5.0 Google rating.

Top Notch Billing & Management Services has carved out a specific niche in Chronic Care Management and Remote Patient Monitoring billing valuable if that’s a growing part of your practice.

HMS USA LLC is led by a credentialed billing specialist (CPB, CPC, CFP) and blends traditional RCM with modern patient-facing systems.

Millennium Medical Billing stands out for keeping all operations domestic, with 15+ years focused specifically on specialty practices.

Transcure offers an AI-powered billing platform bundled with service delivery, appealing to practices that want more direct technology control.

PRGMD serves all 50 states while maintaining New York-specific knowledge, a fit for multi-state groups.

CareCloud is a publicly traded company offering billing bundled into a broader practice-management and EHR platform, which suits practices wanting one system for everything.

What to Look For, Regardless of Which Company You Choose

1. Ask for real numbers. Clean claims rate, denial rate, and average days in AR and ask whether those numbers are independently audited or self-reported.
2. Check outside sources. BBB, Trustpilot, Google, and Clutch reviews tell you more than a company’s own homepage.
3. Confirm New York-specific experience, particularly with Medicaid MCOs and No-Fault claims if relevant to your practice.
4. Get pricing in writing, including whether fees are calculated on gross charges or net collections.
5. Ask about contract length and transition support, especially how a new partner handles your outstanding AR during the switch.
