Hospital billing · New York
Hospital billing services in New York answer to a Medicaid program unlike almost any other: the state pays inpatient stays on an APR-DRG basis, prices most hospital outpatient care through its own Ambulatory Patient Groups (APG) system rather than Medicare's APC logic, and funds safety-net care with one of the largest disproportionate-share (DSH) pools in the nation. 247 Medical Billing Services (247MBS) has run the institutional revenue cycle since 2005, and in a market defined by Northwell Health, NYC Health + Hospitals, Montefiore, and Mount Sinai, dual-methodology fluency and clean UB-04 discipline are what protect margin in a heavily Medicaid-covered population. Every New York facility we serve gets a dedicated account manager, a free 360° reporting dashboard, and HIPAA plus SOC 2 Type II security.
We support the full spectrum of New York hospital operators — large integrated systems such as Northwell Health and the Mount Sinai and Montefiore academic networks, the NYC Health + Hospitals public safety-net system, community and regional hospitals across Long Island, the Hudson Valley, and Western New York, and the critical access hospitals (CAH) that anchor the North Country and rural upstate. We also bill for academic medical centers carrying IME/GME and 340B complexity, hospital outpatient departments and clinics reimbursed through the state's APG system, observation units, and health-system central business offices consolidating multiple hospitals onto a single revenue cycle. Whether you run one community hospital in Buffalo or Rochester or a multi-borough system across New York City, our hospital billing services in New York scale to your case mix, Medicaid share, and chargemaster without adding headcount to your business office.
Traditional Medicare Part A pays inpatient care through IPPS and outpatient through OPPS via the Part A MAC; New York Medicaid pays inpatient on an APR-DRG basis and outpatient through its APG system, both with DSH support; and Medicare Advantage and commercial payers settle on negotiated terms under their own review. The table shows how a New York hospital encounter becomes a paid institutional claim.
| Payment engine | What it depends on | Claim element |
|---|---|---|
| Inpatient weight | Principal + secondary Dx, procedures, CC/MCC, POA | MS-DRG / APR-DRG, bill type 11X |
| Medicaid outpatient | APG grouping, packaging, consolidation | APG line; Medicare APC on 837I |
| Chargemaster line | CDM mapped to services delivered | Revenue codes 0450, 0510, 0636 |
| Status integrity | 2-midnight rule; inpatient-to-outpatient change | Condition Code 44; observation hours |
| Part A MAC | Medicare IPPS/OPPS adjudication | National Government Services (NGS) |
| Medicaid supplements | Safety-net funding; eligibility accuracy | DSH pool + managed-care rates |
The defining challenge of New York facility billing is running two outpatient payment methodologies side by side. A single outpatient visit is grouped one way for Medicare (an APC with status indicators and packaging) and an entirely different way for New York Medicaid (an APG with its own consolidation and packaging logic), so a business office trained only on Medicare rules will under-collect on the very population — Medicaid enrollees — that fills a New York safety-net hospital. Inpatient adds the APR-DRG layer, where documented severity and clinical-validation readiness set the weight, and the state's large DSH pool makes eligibility and cost-report accuracy part of the revenue cycle. New York City's dense Medicaid managed-care market compounds it: dozens of plans, each with its own authorization and notification rules. 247MBS runs New York hospital accounts so Medicare APC and Medicaid APG grouping, APR-DRG inpatient coding, and CDI move as one coordinated workflow instead of colliding at the claim edit.
New York leaks concentrate where the two payment systems meet. The most common loss is a Medicaid outpatient claim priced on Medicare assumptions instead of the state's APG grouping, which quietly under-reimburses high-volume clinic and emergency-department visits. Right behind it are inpatient-versus-observation downgrades under the two-midnight rule from Medicare Advantage plans, DRG downgrade and clinical-validation denials on inpatient stays, and authorization or notification gaps across the state's crowded managed-care market. The structural traps round it out — present-on-admission edits, 72-hour-window services billed separately, and readmission and timely-filing denials.

The decision to outsource the hospital revenue cycle in New York usually turns on methodology fluency. Can an in-house office code inpatient to APR-DRG, price outpatient correctly under both Medicare APC and New York's APG system, keep DSH eligibility clean, chase authorizations across dozens of Medicaid managed-care plans, and still work DNFB down daily? For most New York hospitals that is more coordination than a strained business office can hold. As a medical billing services company built for institutional facility work, 247MBS runs the entire cycle — patient access and eligibility, HIM coding and CDI, charge integrity and denial management, utilization-review support, and A/R recovery — under one accountable team. Our metrics are dependable: a 99% first-pass clean-claim rate, up to 40% fewer denials, 90% of worked denials recovered, and days in A/R under 25, backed by 98% client retention across two decades of professional hospital work. We are not a general billing company learning the APG system on your dime; we are a facility-focused billing services company that already knows how New York's dual Medicaid methodology behaves. See how our statewide footprint works on the New York billing overview.
New York hospitals bring in 247MBS to collect the full Medicaid rate on the population that fills their beds and clinics. We run medical billing for hospitals across the state's dual methodology — APR-DRG inpatient grouping, Ambulatory Patient Group outpatient pricing that differs from Medicare's APC logic, and one of the nation's largest DSH pools — as one accountable UB-04 workflow. HIM coding, CDI, dual APG/APC grouping, and payer follow-up move together, so a Buffalo community hospital or a multi-borough New York City system holds a 99% first-pass clean-claim rate and days in A/R under 25. Since 2005 we have defended facility margin against observation downgrades and under-priced outpatient claims. Request a revenue review and see what your business office is leaving uncollected.
Yes. We group and price hospital outpatient claims to the state's Ambulatory Patient Groups methodology, distinct from Medicare's APC logic, so clinic, emergency-department, and ancillary services are reimbursed at the correct Medicaid rate instead of being under-collected.
Yes. We code inpatient stays to the all-patient-refined DRG with clinical-validation-ready documentation and keep the eligibility and reporting behind disproportionate-share funding accurate so safety-net facilities collect the supplemental dollars they are owed.
We verify plan assignment at registration, track each plan's authorization and notification rules, and work managed denials plan by plan so the density of MCOs across the five boroughs does not translate into avoidable write-offs.
We work to a 24-hour submission standard once coding and documentation clear the pre-bill triple-check, so charges, grouping, eligibility, and authorization are reconciled before the claim drops rather than after a denial.
Whether you are a solo practice or a multi-site group, we bill Hospital across New York under one dedicated account manager and a live dashboard — and treat every counted unit, authorization and appeal as recoverable revenue until it is safely paid.
