Top 10 Medical Billing Companies in New York
1. Swift Medical Billing: Best for Full-Service Revenue Cycle Support
Swift Medical Billing supports eligibility, charge entry, claim submission, payment posting, denial follow-up, accounts receivable, and reporting. The company fits practices that want a managed team instead of software alone.
Its broader healthcare revenue cycle management services connect billing with front-end and follow-up workflows. A New York practice should confirm responsibility for managed care verification, authorizations, provider enrollment, patient balances, and any specialty claim requirements.
Best for: Practices seeking end-to-end outsourcing and a single accountable billing workflow.
2. AffinityCore: Best for Connected Full-Cycle RCM
AffinityCore presents its service as a coordinated revenue cycle model covering billing, coding, credentialing, denials, and A/R. Its New York positioning makes it relevant for practices looking for a local full-service alternative.
Best for: Small and mid-size practices seeking coordinated billing support. Verify specialty references, staffing, reporting, and the exact services included in the fee.
3. Credex Healthcare: Best for Billing and Credentialing
Credex Healthcare combines revenue cycle services with provider credentialing and payer enrollment. That pairing can help groups adding clinicians or contracts, since claim payment depends on correct participation and enrollment data.
Best for: Growing practices that need billing and enrollment under one vendor. Require separate timelines, responsibilities, and status reporting for credentialing.
4. Core Med Billing: Best for Local Independent Practices
Core Med Billing operates from Brooklyn and focuses on personalized medical billing support. Boutique providers can offer direct communication, though buyers should evaluate backup staffing and the ability to handle volume growth.
Best for: Solo providers and small groups that value a close local relationship. Ask how complex appeals and staff absences are covered.
5. HMS USA: Best for Multi-Specialty Billing
HMS USA offers medical billing, coding, A/R, credentialing, and related revenue cycle services. Its broad specialty coverage can suit groups that need different coding workflows under one reporting structure.
Best for: Multi-specialty practices. Request sample reports segmented by specialty, provider, payer, location, and aging bucket.
6. Millennium Medical Billing: Best for Independent Specialty Practices
Millennium Medical Billing serves New York practices with outsourced billing and revenue cycle support. Its local-service model may appeal to independent practices that want direct access to their billing team.
Best for: Small and mid-size specialty groups. Confirm EHR compatibility, escalation procedures, contract flexibility, and post-termination claim responsibility.
7. iRCM: Best for Technology-Assisted Workflows
iRCM combines managed revenue cycle services with automation and reporting tools. This approach may fit organizations that want operational support along with technology for claim tracking and analytics.
Best for: Technology-oriented practices. Ask which tasks are automated, which receive human review, and how exceptions are escalated.
8. MediBillMD: Best for Multi-Specialty Physician Groups
MediBillMD provides billing, coding, denial management, credentialing, and A/R services across multiple specialties. It is a potential option for practices that want a managed team without moving to an enterprise platform.
Best for: Small and mid-size physician groups. Verify client references in the same specialty and payer mix.
9. BellMedEx: Best for Denials and Aged A/R
BellMedEx offers full medical billing together with denial and accounts receivable support. Practices with old balances should separate current billing from recovery inventory so performance can be measured accurately.
Best for: Groups with recurring denials or aging receivables. Define appeal authority, closure rules, fees, and reporting before transferring accounts.
10. Sunknowledge Services: Best for High-Volume Specialty Work
Sunknowledge Services supports medical billing, coding, prior authorization, DME, and other specialty workflows through a large delivery model. Its scale may suit organizations with substantial transaction volume.
Best for: Mid-size and enterprise organizations. Confirm team location, security, quality controls, service levels, and workflow ownership.
What Makes Medical Billing Different in New York?
Medicaid Managed Care
New York Medicaid managed care involves multiple health plans and program types. Provider enrollment with New York Medicaid does not automatically confirm participation with every managed care plan. Practices need to verify member eligibility, the responsible plan, network status, authorization, covered services, and claim submission rules for each encounter.
A billing partner should monitor updates from the New York State Department of Health and eMedNY, maintain payer-specific workflows, and distinguish fee-for-service Medicaid from managed care claims. Credentialing errors, incorrect plan selection, and missing authorizations can stop payment before coding accuracy is considered.
Prompt-Pay Requirements
New York Insurance Law includes standards for prompt, fair, and equitable settlement of covered healthcare claims. Timing can depend on whether the claim is complete, how it was transmitted, whether the payer requests additional information, and whether the plan is subject to the law.
Prompt-pay rules do not replace follow-up. Billing teams should track receipt dates, requests for information, responses, adjudication, interest when applicable, and complaint rights. Legal applicability should be reviewed with qualified counsel or the appropriate regulator.
Surprise Billing and Out-of-Network Claims
New York has protections for certain surprise and emergency medical bills. The rules differ based on plan funding, network status, setting, service, and date. The New York Department of Financial Services guidance explains protections and the state’s independent dispute resolution process.
Practices need accurate network verification, required notices, patient cost-sharing controls, and documentation for any dispute. A billing vendor should not balance-bill a patient simply because an out-of-network claim paid less than expected.
Workers’ Compensation Billing
New York Workers’ Compensation claims follow Board rules, fee schedules, authorization processes, and dispute procedures. The Board states that, beginning August 1, 2025, healthcare providers in the workers’ compensation system must submit the CMS-1500 electronically through an approved submission partner.
The New York Workers’ Compensation Board CMS-1500 guidance should be checked for current requirements. A general commercial-claim workflow is not enough for workers’ compensation billing.
Best Companies by Practice Type
Solo and small practices: Swift, Core Med Billing, Millennium Medical Billing, MediBillMD, and AffinityCore are relevant candidates. The right choice depends on whether the practice wants full outsourcing or selected support.
Multi-specialty groups: Swift, HMS USA, iRCM, BellMedEx, and Sunknowledge offer broader delivery models. Ask how the company separates performance by specialty, payer, provider, and location.
Practices adding providers: Swift, Credex, HMS USA, and MediBillMD offer credentialing support. Swift’s medical credentialing services can be coordinated with billing, but enrollment timelines and ownership should remain separately documented.
Denial-heavy practices: A vendor should categorize denials by payer, code, reason, provider, and root cause. Swift’s denial management services combine recovery with prevention instead of treating each denial as an isolated event.
How Much Do Medical Billing Companies Charge?
New York billing companies may charge a percentage of collections, a per-claim fee, a flat monthly amount, or a dedicated-team rate. Pricing depends on specialty, volume, payer mix, service scope, location count, and the condition of existing A/R.
Compare proposals with identical assumptions. Confirm whether coding, eligibility, authorizations, credentialing, patient statements, appeals, old A/R, postage, clearinghouse fees, and system migration are included. Determine whether the percentage applies to insurance payments, patient payments, or both.
How to Choose a New York Billing Company
- Request references from New York clients with the same specialty and practice size.
- Verify experience with the practice’s Medicaid managed care, commercial, Medicare, workers’ compensation, and no-fault mix.
- Test the real EHR, clearinghouse, and payer portal workflow.
- Define charge lag, first-pass acceptance, denial rate, A/R days, and net collection rate in writing.
- Confirm data security, a business associate agreement, access controls, and incident procedures.
- Identify who handles coding questions, authorizations, appeals, enrollment, and patient calls.
A pre-transition medical billing audit can establish baseline performance and reveal recurring issues before proposals are compared.
Contract Red Flags
Warning signs include guaranteed financial outcomes, metrics without formulas, long lock-in periods, unclear termination fees, restricted data access, and no written responsibility for claims after the contract ends. A proposal should state every included and excluded service.
Confirm data ownership, export format, access to payer portals, and whether the vendor can hold payments. Insurance and patient funds should follow the practice’s approved financial controls rather than an unclear vendor process.
How to Switch Without Interrupting Cash Flow
Create a transition plan covering payer portals, clearinghouse enrollment, EHR access, open claims, payment posting, patient balances, appeals, and provider enrollment. Divide responsibility by dates of service and keep old system access until all outstanding work has an owner.
During the first weeks, monitor charge lag, claim rejections, denials, payments, and A/R aging. Practices considering complete medical billing outsourcing should compare launch performance with the documented baseline.
