Medical Billing Services in New York
Built for a state where the Medicaid filing window is 90 days — and everything else is just as specific.
New York gives providers one of the shortest Medicaid timely filing windows in the country and one of the most fragmented payer mixes. A practice in Buffalo works with Independent Health and Univera; the same specialty in Queens lives on Healthfirst, Fidelis Care, and EmblemHealth. Layer on the Prompt Pay Law, a surprise-bill arbitration system that predates the federal No Surprises Act, and a Medicaid program replacing its provider enrollment infrastructure in 2026, and revenue cycle work here becomes its own discipline. Mental Health Billing remotely supports healthcare providers throughout New York; this page covers what actually determines whether a New York practice gets paid.
The New York Payer Environment in 2026
Roughly seven million New Yorkers have Medicaid, over 4.5 million of them in mainstream managed care plans such as Healthfirst, Fidelis Care, MetroPlus, EmblemHealth, Molina, and UnitedHealthcare Community Plan, plus regional plans like MVP and CDPHP upstate. Fee-for-service claims run through eMedNY, but the real workload is managed care: each plan keeps its own credentialing application (typically 90 to 120 days), prior authorization lists, and claim edits.
Two structural rules trip up teams new to the state. Every managed care network provider must also be enrolled with New York State Medicaid under the 21st Century Cures Act — plans screen against the state database and can remove providers who never completed enrollment. And that process changed in 2026: the Department of Health moved new enrollments and five-year revalidations for all provider types into the new Medicaid Provider Services Portal (PSP), phasing out the paper workflow.
The commercial market splits by geography: downstate means UnitedHealthcare/Oxford, Anthem Blue Cross Blue Shield (still "Empire" to many New Yorkers), EmblemHealth's GHI and HIP lines, Aetna, and Cigna, while Excellus BlueCross BlueShield, Independent Health, Univera, MVP, and CDPHP dominate upstate regions. Systems like Northwell, NewYork-Presbyterian, Mount Sinai, NYU Langone, and Montefiore keep absorbing practices, but behavioral health and much of primary care remain independent — exactly where billing infrastructure is thinnest.
One 2026 disruption is unavoidable: federal H.R. 1 funding cuts ended Essential Plan coverage for enrollees between 200 and 250 percent of the federal poverty level on July 1, 2026, sending roughly 450,000 New Yorkers to Qualified Health Plans mid-year. Claims for those members with dates of service after June 30 under the old product will deny, so re-verify eligibility at every visit.
Billing Rules That Only Exist in New York
Each rule below is indexed to the statute, regulation, or program that creates it — because in New York, the citation is the workflow.
The 90-day Medicaid clock
New York Medicaid claims are due within 90 days of the date of service — most states allow 180 to 365. Late claims require a documented delay reason code, and managed care contracts set their own limits, often just as short. A two-week charge entry lag that is harmless elsewhere becomes unrecoverable revenue here.
The Prompt Pay Law
Insurers and HMOs must pay clean claims within 30 days when submitted electronically (45 on paper) or owe interest of at least 12 percent per year, enforceable through a complaint to the Department of Financial Services. Few practices reconcile payment dates against receipt dates, so interest owed goes uncollected.
Telehealth payment parity through 2028
New York extended payment parity — telehealth paid at the same rate as in-person care across Medicaid and state-regulated commercial plans — through April 1, 2028, with carve-outs for Article 28 facility fees. Capturing it still requires correct modifiers (95, or 93 for audio-only) and place of service (02/10); miscode and the plan pays less.
Behavioral health has its own architecture
Office of Mental Health–licensed Article 31 clinics bill Medicaid under the Ambulatory Patient Group (APG) methodology — rate codes, procedure weighting, and edits that exist essentially nowhere outside New York. Adults with serious mental illness or substance use disorders may be in HARP plans with added Behavioral Health HCBS benefits, and commercial payers routinely flag 90837 utilization, so session-length documentation matters.
OMIG oversight
New York's Office of the Medicaid Inspector General runs one of the country's most active audit and self-disclosure programs, with extrapolated recoveries — units, modifiers, supervision, and treatment plans must survive a chart review, not just a claim edit.
Separate statutes for accident care
No-fault auto claims under Regulation 68 must generally be billed within 45 days of treatment, and workers' compensation follows the state fee schedule through OnBoard — real revenue for practices in the boroughs and on Long Island. New York also runs its own surprise-bill dispute process (since 2015) and a DFS external appeal for medical-necessity denials that many practices never use.
How Mental Health Billing Addresses Each of These
Our workflow is built around the rules above, not a national template. Eligibility runs through ePACES and plan portals before visits — which this year means catching former Essential Plan members whose coverage changed July 1. Claims are coded, scrubbed against payer-specific edits, and submitted within days, tracked against the 90-day Medicaid window. Denials are worked payer by payer, and when a plan pays late we calculate and pursue § 3224-a interest rather than writing it off. Credentialing covers PSP enrollment and revalidation, CAQH maintenance, and every managed care and commercial panel separately — in New York there is no single door.

This is where New York's complexity peaks: Article 31 clinic billing differs completely from private-practice psychotherapy billing, HARP enrollment changes the benefit set, and parity violations by commercial plans are appealable through DFS.
Primary care is navigating the 1115 waiver era — health-related social needs screening, Social Care Network referrals, and enhanced payment tied to PCMH recognition, funded through March 2027.
Physical therapy, chiropractic, and pain practices juggle no-fault and workers' comp deadlines alongside commercial claims.
Specialists face prior authorization lists that differ by Medicaid managed care plan for the same CPT code.
A Revenue Cycle Built for a 90-Day State
- Verify before the visitEligibility through ePACES and plan portals — catching mid-year coverage changes.
- Code at charge entryCoding review at the point of charge capture, not after the denial.
- Scrub for the payerClaims checked against payer-specific edits before they leave.
- Submit 837P dailyDaily electronic submission keeps every claim far inside the 90-day window.
- Post 835s same weekPayment posting from remittance files within the week, so timing is auditable.
- Triage denials in 48hEvery denial worked within two business days, payer by payer.
- Appeal to the endAn appeal ladder ending at the DFS external appeal when medical necessity is disputed.
The emphasis is prevention: when your largest payer's filing window is 90 days, a claim touched twice is a claim at risk.
Why Outsourcing Makes Financial Sense in New York
Billers who genuinely know eMedNY, APGs, and a dozen plan portals command well above national salaries in the New York City metro, and losing one mid-year can stall cash flow entirely. Outsourcing converts that fixed cost into a predictable percentage of collections, adds audit-ready habits in an OMIG-active state, and typically recovers revenue — late-payment interest, appealable denials, missed crossovers — that a stretched in-house team leaves behind. We support solo practices in the North Country as readily as groups in Manhattan; the work is remote by design.
Frequently Asked Questions
What is the timely filing limit for New York Medicaid?
Ninety days from the date of service for fee-for-service claims, with limited exceptions documented through delay reason codes. Managed care plans set their own contractual limits, so read each participation agreement.
Do New York insurers really owe interest on late payments?
Yes. Under Insurance Law § 3224-a, clean electronic claims paid after 30 days accrue interest, with escalation available to the Department of Financial Services. It only gets collected if someone tracks it.
How should we handle former Essential Plan patients right now?
Re-verify coverage at every visit through the rest of 2026. About 450,000 members lost Essential Plan eligibility on July 1, and many are moving to marketplace plans with different networks, cost-sharing, and payer IDs.
Can you bill for OMH-licensed Article 31 clinics?
Yes — including APG rate codes, modifiers, and New York's clinic-specific edit logic, alongside standard CPT billing for private behavioral health practices.
Do you work with upstate and rural practices?
Yes. We remotely support healthcare providers throughout New York, from Western New York and the Southern Tier to Long Island.
