From our office in Melville, Long Island, Fast Billing Solutions helps private practices across Nassau County get paid faster and more completely. We’re not a distant national call center — we’re a Long Island medical billing company headquartered minutes from the Nassau–Suffolk border, and we understand New York payers, NY Medicaid enrollment, no-fault and workers’ compensation billing, and what it really takes to run a profitable practice here in Nassau County.
A Billing Partner That Knows Nassau County Healthcare
Nassau County’s healthcare market is one of the densest — and most competitive — in the New York metro area. Major health systems anchor the county: Northwell Health’s North Shore University Hospital in Manhasset, Long Island Jewish Medical Center on the county’s western edge, NYU Langone Hospital–Long Island in Mineola, Mount Sinai South Nassau in Oceanside, and Nassau University Medical Center in East Meadow. Yet between these giants, thousands of independent private practices thrive: orthopedics in Garden City, cardiology in Great Neck, dermatology in the Five Towns, ENT in Syosset, gastroenterology in Hicksville, physical therapy groups in Massapequa, urgent care centers along Hempstead Turnpike, and podiatry, ophthalmology, behavioral health, oral surgery, and urology practices in nearly every Nassau town and village.
Every specialty — and every payer contract — carries its own billing rules. Nassau practices draw patients from across Long Island, Queens, and the five boroughs, which means juggling commercial plans, NY Medicaid, Medicare Advantage, no-fault auto, and workers’ compensation claims in a single week. We represent 20+ physician specialties, bill more than $60 million in claims annually, and hold an average 98% net collection rate — for practices of every size, from solo physicians to multi-location groups.
Billing Pain Points We Solve for Nassau County Practices
These are the problems Nassau County practices bring to us most often — and the ones we fix first:
- New York payer credentialing and enrollment. CAQH, NPI, Medicare (PECOS), NY Medicaid through eMedNY, plus commercial credentialing with Empire BlueCross BlueShield, UnitedHealthcare/Oxford, Aetna, Cigna, EmblemHealth (GHI/HIP), Healthfirst, and Fidelis Care. Because Nassau patients routinely cross county lines, a single lapsed enrollment means denied claims — we keep every provider current. Learn about our credentialing services.
- No-fault and workers’ compensation billing. NY auto no-fault (PIP) and Workers’ Compensation Board claims run on their own forms, fee schedules, authorization rules, and strict timely-filing windows. Nassau’s busiest corridors — the LIE, Northern State Parkway, Sunrise Highway, and Hempstead Turnpike — generate a steady stream of accident and work-injury cases. We handle these claims every day for practices that treat them.
- Denials and prior authorizations. Commercial payers deny aggressively — medical necessity, coding edits, missing authorizations. Our denial management team works every denial to resolution and fixes the root cause.
- The cost of in-house billing staff. Hiring and retaining billing staff in Nassau County is expensive, and turnover stalls cash flow. Outsourcing gives you a full revenue-cycle team for less than the cost of one experienced in-house biller.
- No visibility into your revenue cycle. Daily, weekly, and monthly reports plus customized reporting, so you always know what’s billed, paid, and outstanding.
