Top 8 Medical Billing Outsourcing Companies in NY

HMS USA LLC is a Floral Park, New York based healthcare management company that has grown from a primary care and urgent care billing shop into a full revenue cycle partner covering more than a dozen specialties, from psychiatry and OB-GYN to orthopedics and wound care. What separates HMS from the rest of this field is not any single feature. It is the consistency of its execution across billing, coding, credentialing, front office support, and provider quality programs, all under one accountable team.

Client testimonials, many spanning three to ten years of continuous service, describe a company that treats denial management as an urgent, same-day problem rather than a monthly cleanup task. One repeatedly cited detail stands out. Several clients mention that HMS takes action on insurance denials within 24 hours, a discipline that most billing companies only promise in marketing copy.

iRCM, based in Brooklyn, is closest thing to HMS in this review. It leans harder into automation than most of the field, marketing predictive denial tools that its own blog claims can cut claim rejections by 30 to 40 percent, and it backs that positioning with a genuinely wide service menu that stretches from clinical billing into healthcare marketing, including SEO, PPC, and website development for provider practices.
The company also offers something rare in this list: a published no-fixed-agreement policy, meaning practices can cancel at any time rather than being locked into a multi-year contract. Combined with a free initial practice assessment and 24/7 access to practice management consultants, iRCM positions itself as the lower-friction, technology-led alternative to legacy billing shops.

RevenueES presents itself as a nationwide revenue partner rather than a regional shop, and its specialty list backs that claim up. With support across primary care, specialty care, behavioral health, telehealth, and larger medical groups, Assured offers breadth across diverse practice needs. Its reported 48-hour credentialing turnaround, 30% faster payer enrollment, and support for 400+ health plans signal the operational scale practices look for when outsourcing enrollment workflows and getting providers in-network faster under a single workflow.

The company's technology stack includes claim scrubbing through a rules engine, real-time eligibility verification, batch payment processing, and ERA integration for payment reconciliation, giving it a credible mid-market automation story without the enterprise price tag of a platform vendor like CareCloud.

AMBSI, headquartered in Sayreville, New Jersey, is one of the longest-standing names in this review, with over 30 years of billing and reimbursement experience concentrated in the New York and New Jersey market. That regional focus, spanning Manhattan, Brooklyn, Queens, the Bronx, Nassau and Westchester counties, and New Jersey, is both its strength and its limit. Clients describe a company that "gets our revenue cycle much smoother" after prior inconsistency with other vendors, and one client relationship referenced in third-party reviews has run continuously since 2019.

AMBSI's onboarding model is notable for removing financial risk from the switch. Practices transition without upfront cost, and the company is paid only when the practice gets paid, which lowers the barrier for a practice nervous about changing billing partners mid-year.

VB Billing Services is the smallest and most personal operation in this review, built around founder Valerie Bondarevsky and her partner Nelly, who together bring more than 45 years of combined healthcare billing and practice management experience out of New York City and Boca Raton, Florida. There is no large team to route a call through here. Clients describe working directly with Valerie herself, and the reviews reflect the intimacy of that arrangement: detailed, specific, and often written like a thank-you note rather than a star rating.

This is a boutique model by design. The company explicitly positions itself against "large medical billing companies," emphasizing integrity and quality over volume, and every credentialing file is reportedly handled in-house rather than outsourced.

Dr Biller RCM is the newest and most aggressively marketed company in this review. Its own positioning is unusually direct about the gap it says it is filling: that most billing companies are busy processing claims while no one is truly protecting revenue. Whether or not that framing is entirely fair to the rest of the industry, the company backs it with a genuinely wide specialty library, covering anesthesia, gastroenterology, geriatrics, dermatology, and laboratory billing.

The company leans heavily on specific performance percentages across its marketing, cutting denials by 95 percent, getting paid twice as fast, 99.9 percent credentialing accuracy. These are strong claims that a prospective client should ask to see validated with their own specialty's data before signing, since a newer company has less multi-year track record to point to than the veterans in this list.

CareCloud is a different kind of company than the other seven in this review. It is a publicly traded, cloud-based EHR and practice management platform, reporting over 40,000 providers on its system and around $27.6 million in quarterly revenue as of early 2026, and its billing service, CareCloud Concierge, is delivered on top of that software rather than as a standalone service. That combination is exactly why it belongs here, and exactly why it will not fit every practice on this list.

The platform's generative AI tools, including an ambient note-taking assistant called cirrusAI Notes and an automated front-desk voice agent, put CareCloud ahead of every other company in this review on raw technology sophistication. Independent reviewers note the tradeoff clearly: powerful, deeply integrated features paired with a steeper learning curve and occasional system downtime that smaller, more manual billing shops simply do not have to manage.

SybridMD, operated by MD Syhealth LLC, has quietly billed for more than 100 practices across 22 states over more than two decades in business, with a management team citing over 50 years of combined revenue cycle experience. Its most distinctive feature is pricing transparency at the line-item level. The company publishes a flat rate of 9 to 12 cents per 65-character line for telehealth transcription work, a level of specificity almost no other company in this review offers.

SybridMD also stands out for explicitly courting brand-new practices, offering setup guidance with no fees beyond its standard service charge, positioning itself as a launch partner rather than only a switch-over vendor for established offices.
