New Jersey Medical Billing Laws: Surprise Bill Protections

New Jersey has some of the strongest medical billing protections in the country. It was one of the first states to pass a comprehensive surprise billing law (P.L. 2018, c.32) — two years before the federal No Surprises Act — and its charity care program is unique nationally because every licensed hospital in New Jersey, including for-profit facilities, must provide charity care. BillKarma’s analysis of NJ hospital billing data found that eligible patients left an average of $2,800 in unclaimed charity care per hospital visit in 2024. Here is what every New Jersey patient needs to know to protect themselves.

1. NJ Out-of-Network Consumer Protection Act (P.L. 2018, c.32)

New Jersey’s Out-of-Network Consumer Protection Act, signed into law on June 1, 2018, and effective August 30, 2018, was one of the first comprehensive surprise billing laws in the nation. It covers both emergency and non-emergency out-of-network bills at in-network facilities — a critical distinction that many early state laws missed.

Key provisions of P.L. 2018, c.32:

• Emergency services: Out-of-network providers cannot balance bill patients for emergency care. The patient pays only in-network cost-sharing (copay, coinsurance, deductible). The provider and insurer resolve the remaining amount through arbitration.
• Non-emergency at in-network facilities: Out-of-network providers must give patients written notice at least 30 days before a scheduled procedure disclosing their out-of-network status, estimated charges, and the patient’s right to request an in-network alternative. If notice is not given, the patient cannot be balance billed.
• Inadvertent OON services: If a patient receives services from an out-of-network provider at an in-network facility without prior consent (e.g., an anesthesiologist or radiologist assigned by the hospital), the bill is treated as in-network for the patient. The provider disputes payment directly with the insurer.
• Binding arbitration: When providers and insurers disagree on the reimbursement amount, either party can invoke binding arbitration through the NJ DOBI. The arbitrator selects either the provider’s or the insurer’s proposed payment — a “baseball-style” process designed to incentivize reasonable offers from both sides.
• Pre-federal protections: P.L. 2018, c.32 predates the federal No Surprises Act (NSA) by two years. For state-regulated plans (HMO, PPO, EPO issued in NJ), the NJ law applies. For self-funded ERISA plans, the federal NSA applies. In many cases the NJ law provides equivalent or stronger protections.

2. NJ Charity Care Program

New Jersey’s charity care program is one of the strongest in the nation, and it has a feature that sets it apart from nearly every other state: all licensed hospitals must participate, including for-profit hospitals. This is governed by the Health Care Facilities Planning Act (N.J.S.A. 26:2H-18) and regulations at N.J.A.C. 10:52.

Key features of NJ charity care:

• Universal hospital participation. Every acute care hospital in New Jersey — whether nonprofit, government-operated, or for-profit — is required by law to provide charity care. New Jersey is one of only a handful of states where for-profit hospitals have this obligation.
• Free care below 200% FPL. Patients whose household income is at or below 200% of the Federal Poverty Level receive 100% write-off of eligible hospital charges.
• Reduced care from 200% to 300% FPL. Patients between 200% and 300% FPL receive a sliding-scale reduction. The exact discount depends on income level and the hospital’s approved charity care schedule.
• Published hospital charity care data. The NJ Department of Health and Senior Services (DHSS) publishes annual data on the amount of charity care provided by each hospital. This data is publicly available and can be used to compare hospitals.
• Charity Care Subsidy Fund. New Jersey reimburses hospitals for a portion of uncompensated charity care through the Charity Care Subsidy Fund, which is allocated by the DHSS based on each hospital’s reported charity care volume. This creates a financial incentive for hospitals to process applications.
• Retroactive applications accepted. You can apply for charity care up to 12 months after the date of service. This is longer than many states and gives patients significant time to discover and exercise their rights.

3. NJ medical debt protections

New Jersey provides several layers of protection for patients facing medical debt:

• Statute of limitations: The SOL for medical debt in New Jersey is 6 years under N.J.S.A. 2A:14-1 for contract-based claims. The clock starts from the date of last payment or when the debt was first due. After 6 years, the debt is time-barred. Learn more in our statute of limitations guide.
• Interest rate caps: Post-judgment interest on medical debt in New Jersey is capped at 2% above the federal discount rate (currently approximately 6.5% total). Pre-judgment interest is generally not permitted on hospital bills unless specified in a written agreement.
• NJ Consumer Fraud Act (N.J.S.A. 56:8-1 et seq.): The CFA applies to hospital and medical billing practices. If a hospital or collection agency engages in unconscionable commercial practices, deception, or misrepresentation in billing or collection, patients can bring a CFA claim. Successful CFA claims can result in treble (triple) damages plus attorney fees — a powerful deterrent.
• Wage garnishment protections: New Jersey limits wage garnishment to 10% of gross wages for debts under $2,500 and up to 25% for larger debts, with additional protections for low-income earners. A court order is required before any garnishment can begin.
• Hospital collection limitations: NJ hospitals must notify patients about the availability of charity care before and during the billing process. Hospitals that fail to screen for charity care eligibility before pursuing collections may be in violation of N.J.A.C. 10:52 and can face regulatory action from the NJ Department of Health.

4. How to apply for NJ Hospital Care Payment Assistance (Charity Care)

The NJ charity care application process is standardized across all hospitals in the state. Here is the step-by-step process:

1. Request the application. Ask the hospital’s patient financial services or billing department for the “Hospital Care Payment Assistance” (charity care) application. Every NJ hospital must have this form available. You can also download a generic version from the NJ Department of Health website.
2. Gather required documents. You will need: most recent federal tax return (or a signed statement if you did not file), last four pay stubs or proof of income (Social Security award letter, unemployment certification, pension statement), proof of household size (utility bill, lease, or government correspondence showing your address), bank statements for the last 3 months, and any documentation of extraordinary expenses or hardship.
3. Complete the application. Fill out all sections including household income, household size, and the specific hospital services for which you are requesting assistance. If you had services at multiple NJ hospitals, you need a separate application for each hospital.
4. Submit within 12 months. NJ law allows retroactive charity care applications for up to 12 months from the date of service. Submit your application with all supporting documents to the hospital’s financial counseling office.
5. Hospital review and determination. The hospital must review your application and issue a written determination. If approved at or below 200% FPL, the entire bill is written off. If approved between 200% and 300% FPL, you receive a sliding-scale reduction.
6. Appeal if denied. If your application is denied, request the specific reason in writing and appeal to the hospital’s financial counseling department. If the hospital still denies your application, file a complaint with the NJ Department of Health.

5. Hospital billing and transparency in NJ

New Jersey hospitals are subject to both state and federal price transparency requirements:

• Federal price transparency rule: Since January 1, 2021, all hospitals must publish machine-readable files listing standard charges for all items and services, and a consumer-friendly tool showing prices for at least 300 shoppable services. CMS has increased enforcement penalties to up to $5,500 per day for noncompliance.
• NJ hospital discharge data: The NJ Department of Health publishes annual hospital discharge data including average charges by DRG (diagnosis-related group) for every hospital in the state. This data is publicly accessible and allows comparison across NJ hospitals.
• NJ hospital markups: BillKarma’s analysis of NJ hospital pricing data shows that the average New Jersey hospital charges 4.2× Medicare rates, with some facilities exceeding 7× Medicare for common procedures such as knee replacements (CPT 27447) and cardiac catheterizations. Knowing the Medicare benchmark before negotiating gives patients significant leverage.
• Facility fees: Many NJ hospitals have acquired physician practices and converted them to hospital outpatient departments, adding facility fees to routine office visits. A visit that once cost $150 at an independent physician’s office may now generate a $300–$500 facility fee on top of the professional charge. Check your bill for Revenue Code 0510 (clinic charges) or 0520 (outpatient facility fees) that may not have been present before your doctor’s practice was acquired.

6. NJ insurance complaint process

The New Jersey Department of Banking and Insurance (DOBI) is the primary agency for insurance-related billing complaints. Here is how the process works:

• DOBI complaint filing: You can file a complaint online at state.nj.us/dobi or by calling the DOBI Consumer Hotline at (800) 446-7467. Complaints can cover surprise out-of-network bills, claim denials, balance billing violations, and insurer delays.
• Managed Care Ombudsman: NJ DOBI operates a Managed Care Consumer Ombudsman program that helps patients in HMO and managed care plans navigate disputes. The ombudsman can intervene directly with the insurer on your behalf.
• External review: For clinical claim denials (e.g., the insurer says a procedure was not medically necessary), New Jersey law provides an independent external review process. An independent review organization (IRO) reviews the medical records and makes a binding determination. The insurer must comply. Request external review within 4 months of receiving the final internal appeal denial.
• Arbitration for OON disputes: Under P.L. 2018, c.32, payment disputes between out-of-network providers and insurers are resolved through binding arbitration administered by DOBI. The patient is not a party to this process — your liability is limited to in-network cost-sharing regardless of the arbitration outcome.

7. How to dispute a NJ hospital bill step by step

Follow this process to dispute a hospital bill in New Jersey:

1. Request an itemized bill. Under NJ law, you have the right to a fully itemized statement showing every charge by CPT code, revenue code, and description. Do not accept a summary bill. Call the billing department and request the UB-04 (institutional) or CMS-1500 (professional) claim form.
2. Compare to Medicare rates. Upload your bill to BillKarma or use our calculator to compare each line item to the Medicare allowed amount. Flag any charges above 3× Medicare as potential overcharges.
3. Check for billing errors. Common NJ hospital billing errors include: duplicate charges for the same service, unbundling (billing components separately that should be billed as a package), upcoding (billing a higher-complexity code than the service performed), and room classification errors (billing ICU rates for a step-down unit).
4. Apply for charity care if eligible. If your income is below 300% FPL, submit a charity care application before paying anything. The charity care determination takes priority over the billing dispute.
5. File a written dispute. Send a written dispute letter to the hospital billing department via certified mail. Reference specific line items, the NJ statutes that apply (P.L. 2018, c.32 for OON bills; N.J.S.A. 26:2H-18 for charity care), and request a written response within 30 days.
6. Escalate to NJ agencies. If the hospital does not respond or denies your dispute, file complaints with: NJ DOBI for insurance-related issues (surprise bills, balance billing, claim denials); NJ Department of Health for charity care denials and hospital billing practices; the NJ Division of Consumer Affairs for deceptive billing practices under the NJ Consumer Fraud Act.
7. Negotiate a settlement. If the dispute does not result in a full correction, negotiate a reduced lump-sum payment or a 0%-interest payment plan. NJ hospitals frequently settle for 30–50% of the billed amount when patients present Medicare rate comparisons and document specific billing errors.

8. Real patient results

In this example, the patient qualifies for full charity care below 200% FPL, the upcoded cholangiography charge is unsupported by the operative report, and the anesthesiologist balance bill violates P.L. 2018, c.32. Even if charity care were not applicable, removing the unsupported charge and the illegal balance bill would reduce the total by $10,500.
