Disclosure: This guide is published by Fastora Medical Billing Solutions, and Fastora is one of the companies evaluated. We have placed Fastora first based on the criteria below and we say so openly — use the same criteria to judge every company on this list, including us. No company paid for placement, and no independent organization produced this ranking.
New York billing runs on deadlines and plan rules. Medicaid fee-for-service claims go through eMedNY and generally must be initially submitted within 90 days of the date of service, with a two-year final submission ceiling under 18 NYCRR 540.6 — miss the window and the claim is gone, not just late. Most Medicaid members, however, sit in managed care, where each plan sets its own filing, authorization, and appeal rules on top of that state framework. Add the downstate concentration of psychiatry and psychology practices and the agency-run frameworks behind behavioral health billing, and a New York billing partner has to be deadline-driven and plan-specific at the same time. This guide compares seven companies that bill for New York practices in 2026. If you want the service itself rather than a comparison, start with Fastora’s medical billing services in New York.
How we evaluated these companies
- eMedNY and timely-filing discipline — does the company run the 90-day fee-for-service window and the two-year final ceiling as tracked deadlines, and handle the fact that managed-care claims follow each plan’s own rules instead?
- Managed-care depth — New York Medicaid is mostly managed care; the company has to enroll providers plan by plan and work each plan’s authorization and appeal process.
- Specialty fit — psychiatry, psychology, and behavioral health are unusually dense in New York, alongside large primary-care and surgical volume; coding and workflow have to match the specialty.
- Denial and A/R work — who appeals and rebills inside the deadline, versus who reports denials after the window has closed?
- Credentialing and enrollment — state enrollment plus separate plan enrollments, maintained over time, not just at setup.
- Practice-size and setting fit — a solo Manhattan practice, an upstate group, and a licensed behavioral health agency are three different billing operations.

1. Fastora Medical Billing Solutions
Fastora is a remote billing partner for New York practices, and its New York workflow is organized around the state’s filing structure: eMedNY fee-for-service deadlines tracked as hard dates, and managed-care claims worked under each plan’s own rules rather than a single assumed timeline. The service covers eligibility verification, coding, claims submission and follow-up, denial management, A/R recovery, payment posting, and credentialing and enrollment support. Specialty coverage includes a dedicated focus on psychiatry billing services, reflecting the downstate concentration of behavioral health practices, and Fastora publishes its medical billing services throughout the country for groups with locations in more than one state.
Fastora reports 50+ active clients and experience supporting 100+ physicians over more than 5 years in medical billing and revenue cycle management. Pricing — a percentage of collections or a flat monthly fee — is quoted after a free billing assessment, and the scope, aged A/R included or excluded, is defined before the engagement starts.
Strengths: the eMedNY deadline structure and per-plan managed-care rules are treated as the operating system of the account, not background knowledge. Considerations: Fastora serves New York remotely, with no New York office — practices requiring a local vendor should weigh that.
Best fit: independent and group practices, including psychiatry and psychology practices, that want filing deadlines, plan enrollment, and denial work managed by one team.
2. iRCM
iRCM is a boutique revenue cycle firm based in Brooklyn. Its published scope covers medical billing, coding, credentialing, claims processing, insurance verification, denial management, and accounts receivable management, and it pairs the billing service with practice-management consulting and practice assessment services. It describes a small, specialized team of coders, billing professionals, and consultants working with medical practices and health centers.
Strengths: a New York-based boutique model with consulting built in, useful when the problem is workflow design as much as claim volume. Considerations: a small team is a deliberate trade-off; high-volume groups should confirm capacity and coverage for their claim load.
3. HMS USA
HMS USA LLC is headquartered in Floral Park, on Long Island, with a second office in Texas. It handles the complete billing cycle for multiple specialties — registration, verification, charge capture, coding, submission, and follow-up — with CPB-certified staff, and layers practice-management services, audit review, credentialing, and EHR implementation support on top. Its workflows are built to comply with federal and state-specific requirements.
Strengths: billing plus practice-management and EHR capability from one Long Island-based vendor. Considerations: the broad service menu means billing-only buyers should define the engagement narrowly and price only what they will use.
4. Millenium Medical Billing
Millenium Medical Billing (MMB) is a Staten Island company, certified as a women/minority-owned business enterprise with New York City and New York State, serving practices in New York, New Jersey, and Florida and clients nationally. Its service list runs from patient billing and coding to credentialing, EHR management, reporting, collections, and payment posting, with published specialty depth in OB/GYN, speech therapy, physical therapy, and general surgery. Its published terms are unusually concrete: billing is submitted within 24 hours, there is no setup fee and no time-binding contract, and fees are a percentage of what is collected each month, varying with practice size and scope.
Strengths: published commercial terms — no setup fee, no long-term contract, percentage-of-collections pricing — reduce the risk of a trial engagement. Considerations: its named specialty depth is narrower than the multi-specialty firms here; confirm experience in your specialty specifically.
5. Millin Medical
Millin Medical, based in Lynbrook, is the specialist on this list: it has focused on behavioral health and human-services billing since 1982, and its model combines a proprietary billing platform (MillinPro) with full billing services, including denial follow-up and resolution. Its published experience is specific to New York’s agency frameworks — Medicaid and Medicaid managed care, and the state offices behind behavioral health and disability services (OMH, OASAS, OPWDD) — with dedicated material for Article 31 mental health clinics, substance-use programs, children’s HCBS, and I/DD providers. Its fee is published as a flat rate based on the work involved in managing claims, rather than a percentage of collections.
Strengths: unmatched New York behavioral-health specificity — the right depth for licensed agencies whose billing lives inside state program rules. Considerations: that focus is the point and the limit; a general medical or surgical practice is outside the model.
6. Medical Billers and Coders (MBC)
Medical Billers and Coders is a national billing company that maintains city-level New York coverage, publishing billing operations for New York City, Buffalo, Rochester, Syracuse, and other New York markets. Its billers and coders work across specialties, including a behavioral health billing practice built on AAPC-certified coders, and its service covers billing, coding, denial management, and credentialing. It publishes New York-specific material on Medicaid managed care requirements.
Strengths: national scale with visible New York-specific material, and specialty-trained billers for practices outside the metro area as well as in it. Considerations: a large multi-city organization — confirm that your account is staffed by the New York team and who your day-to-day contact is.
7. CureMD
CureMD is a healthcare technology company headquartered in New York City, at 80 Pine Street. Its model unifies EHR, practice management, and billing on one platform: documentation flows into claims, eligibility is verified before visits, and its managed billing service adds certified coders handling scrubbing, posting, appeals, and collections. It serves more than 30 specialties, from solo offices to multi-site enterprises, and offers both in-house billing software and end-to-end outsourced RCM.
Strengths: the chart and the claim share one database, which removes a whole class of handoff errors for practices willing to run on its platform. Considerations: the full value depends on adopting CureMD’s EHR — practices keeping their current system should compare the standalone billing service carefully.
How to choose for your New York practice
Begin with the clock. Ask every candidate how it tracks the eMedNY 90-day initial window and the two-year final ceiling, and how its process changes for managed-care members, whose claims follow plan rules instead. A company that answers in generalities about “timely filing” has not shown you a system. Then test Medicaid reality: enrollment is plan by plan, so ask how enrollments are maintained and what happens when a provider joins or leaves. Behavioral health agencies should weight framework-specific experience — Article 31 and the state agency programs are a specialty of their own — while medical and surgical practices should weight coding depth in their specialty and denial turnaround inside filing deadlines. Finally, compare pricing at equal scope, including credentialing and aged A/R, and prefer published terms where they exist.
Frequently asked questions
How does New York Medicaid billing work?
Fee-for-service Medicaid claims are submitted through eMedNY and generally must be initially submitted within 90 days of the date of service, with a two-year final submission ceiling under 18 NYCRR 540.6. Most Medicaid members are in managed care, though, and those claims follow each plan’s own filing deadlines, authorization rules, and appeal processes — which is why a billing partner has to run two rulebooks at once.
What happens if a claim misses the eMedNY filing deadline?
A fee-for-service claim that is not initially submitted within the 90-day window, and not perfected within the two-year final ceiling, is not payable. Deadline tracking, not claim volume, is the first thing to audit in a New York billing operation — the oldest unbilled claims are where the unrecoverable revenue sits.
Does my billing company need to be based in New York?
No. Claims move electronically, and eMedNY and plan rules apply the same way regardless of where the biller sits. What matters is whether the company runs New York’s deadlines and plan enrollments as tracked processes. A New York-based firm may offer local familiarity and easier on-site access; a remote firm with genuine deadline and enrollment discipline will outperform a local one that treats filing windows casually.
How much does outsourced medical billing cost in New York?
The common models are a percentage of collections and a flat monthly fee; one company on this list publishes a flat rate based on workload, and another publishes percentage-of-collections pricing with no setup fee. Rates are only comparable at equal scope — confirm whether credentialing, authorizations, patient statements, and old A/R work are included. Fastora charges a percentage of collections or a flat monthly fee, quoted after a free billing assessment.
What should behavioral health agencies look for in a billing partner?
Framework experience. New York behavioral health billing runs through Medicaid managed care and state agency programs — OMH, OASAS, and OPWDD frameworks, Article 31 clinic rules, and HCBS programs — each with its own rate codes, authorization patterns, and reporting. Ask a candidate to name the programs it bills today and how it keeps up with their rule changes; a generalist answer is a sign to keep looking, and one company on this list is built specifically for this work.
Can a billing company take over our existing accounts receivable?
Yes, most full-service companies will work aged A/R during transition, but in New York the triage order matters: claims closest to a plan deadline or the two-year ceiling get worked first, because the recoverable part has an expiry date. Get the takeover scope in writing — which buckets, which payers, and whether the work is inside the standard rate.
Conclusion
New York punishes billing operations that treat deadlines as guidelines. Compare the seven companies above on eMedNY filing discipline, plan-by-plan enrollment, specialty and framework depth, and pricing scope you can verify — and weight the answers by your own payer mix and denial data.
