What are the essential billing rules and filing requirements for NJ FamilyCare (New Jersey Medicaid)?
NJ FamilyCare is administered by the New Jersey Division of Medical Assistance and Health Services (DMAHS) through five contracted Managed Care Organizations (MCOs): Horizon NJ Health, Wellpoint (formerly Amerigroup NJ), Aetna Better Health of NJ, Fidelis Care, and UnitedHealthcare Community Plan. The standard timely filing deadline is 365 days from the date of service. Providers must verify active eligibility on the 1st of every month via the NJMMIS portal to prevent retro-disenrollment denials. Cross-over claims for dual-eligible Medicare/Medicaid patients require proper secondary billing using CMS-1500 Box 9/11 and appropriate Medicare denial explanation codes.
1. The Structure of NJ FamilyCare Managed Care
NJ FamilyCare provides publicly funded healthcare coverage to eligible low-income adults, pregnant women, and children across New Jersey. While fee-for-service (FFS) Medicaid still exists for institutional care and specialized waivers, the overwhelming majority of outpatient primary care and specialty visits are administered through private managed care organizations.
For healthcare practices in Newark, Paterson, Jersey City, Elizabeth, and Trenton, maintaining active enrollment across all five NJ FamilyCare MCO plans is vital to capturing the full volume of community healthcare demand.
2. Key NJ FamilyCare Billing Specifications
Timely Filing, Prior Auth & EPSDT Coding
• 365-Day Timely Filing: Clean claims must be filed within one year (365 days) from the date of service. For appeals, providers have 90 to 180 days following the initial remittance notice depending on the specific MCO contract.
• Pre-Service Authorizations: MCOs enforce rigorous prior authorization lists for advanced diagnostic imaging (CT, MRI, PET), elective outpatient surgeries, physical therapy beyond initial allotments, and non-preferred pharmaceuticals.
• Early and Periodic Screening (EPSDT): Well-child exams must include developmental screenings (96110), vision/hearing assessments, and lead screening documentation. Ensure the EPSDT checkbox is marked on the electronic 837P file to prevent encounter claim denials.
3. Dual-Eligible (Medicare-Medicaid) Crossover Billing
New Jersey has a significant dual-eligible population. Claims must first be submitted to Novitas Solutions (Medicare Part B Jurisdiction JL).
Once adjudicated by Medicare, the electronic crossover automatically forwards to NJMMIS or the patient's Medicare Advantage dual special needs plan (D-SNP). Our billing specialists track crossover loops (Loop 2320/2330) to reconcile patient co-insurance and deductible balances without manual re-entry.
