This section includes information about:

  • Updates on the Interactive Voice Response (IVR) System.
  • How to access information online through NaviNet®.
  • A listing of the frequently used addresses, phone numbers and fax numbers.

We've also included information about how to access online training courses on Horizon BCBSNJ administrative policies and procedures, and the products and members you serve. Your satisfaction is important to us. We understand that as a health care facility, you may have questions or need information about patients' health care plans outside of our regular business hours. We strive to have systems and processes in place that allow you to contact us in ways that are efficient, flexible and compatible with your needs.


You no longer need to call us to get eligibility, cost-share estimates and to see if the service requires prior authorization for your patients with a member ID number that includes 3HZN. You can easily access this information with ourEligibility and Benefits Cost Share Estimator.

This self-service solution will even give you the information you need at the diagnosis and CPT/Revenue code level as well as a reference number!

Log on to NaviNet and click the link on the Horizon BCBSNJ Plan Central page.


The IVR system expands your options for contacting us, allowing you to obtain the information you need in a more convenient manner. You can access information 24 hours a day, generally including weekends and holidays, and get instant answers to many questions previously handled only by our service representatives.

Not only is the system available when you are, it’s also user-friendly. Our natural speech recognition technology gives you the option of speaking your request in a natural manner, much like you would when speaking with a service representative. You can access the easy-to-use IVR system by calling 1-888-666-2535 and exploring all the information and services that it has to offer.

IVR Tips

Use your natural voice or the touchtone keypad alone to enter the patient’s ID number or navigate through the call.

  • Speak clearly in your natural tone.
  • If accessing the IVR from a noisy environment, mute your phone and use the keypad to enter your responses.
  • Say numbers one digit at a time.
  • When speaking numbers, say Zero rather than O.
  • You may return to the main menu at any time by saying Main Menu. You may also say Repeat or Help.
  • You don’t have to listen to all the options. Go directly to the option you want by using the following voice prompts. Just say...
    • Claims to check claim status or payment.
    • Eligibility and Benefits to verify that a patient is enrolled under a Horizon BCBSNJ plan or to check their benefits (FEP® benefits and eligibility are separate menu options.)
    • Authorizations to request an authorization, check the status of an authorization or find out if an authorization is required.
    • Duplicate Vouchers to request a copy of a voucher by date or by patient. Hospital Services Representatives are available to help you and provide information that you may not be able to access through our IVR system. Call 1-888-666-2535, Monday through Friday, between 8 a.m. to 5 p.m., ET.


All participating facilities are required to register for NaviNet within 30 days of your effective date of participation. Through NaviNet, a multi-payer web portal, your facility has access to the important Horizon BCBSNJ information (eligibility, benefits, claims status, online explanations of payments, submit and check status of UM authorization requests, etc.) that you need to conduct business with us on a day-to-day basis. By using NaviNet, your facility will have access to Horizon BCBSNJ information, as well as the online information of many other New Jersey health plans.

Billing Company Access to NaviNet

If you employ the services of a billing company, we want to remind you that you can help increase their effectiveness and efficiency by encouraging them to register and use NaviNet to carry out their day-to-day responsibilities on your behalf. To register for NaviNet, the billing company should:

  1. Visit and click Sign Up.
  2. Follow the instructions and complete the online NaviNet New Registration Request Application using your company’s tax ID number. Ensure that Yes is selected in response to the question: Is your office a billing agency? Upon submission of the NaviNet New Registration Request Application, a NaviNet enrollment specialist emails an authorization form and instructions to the billing company contact.
  3. Complete the authorization form. The billing company will need to obtain a signature from your office to grant them access to the information on your behalf.
  4. Fax the completed and signed authorization forms to NaviNet to the fax number provided.

NaviNet processes the enrollment request and emails NaviNet login credentials to the billing company contact. If your billing company is registered for NaviNet and does not have access to your information, ask them to forward a copy of the authorization form (see step 3 listed above) they originally received from NaviNet for you to sign. For help registering, call NaviNet Customer Care at 1-888-482-8057.


To help you navigate the health care system, Horizon BCBSNJ offers the Change Healthcare Clear Claim ConnectionTM, a web-based code editing disclosure solution. Clear Claim Connection is designed to help ensure our claim reimbursement policies, related rules, clinical edit clarifications and clinical sourcing information are easily accessible and transparent for our participating doctors and other health care professionals. Clear Claim Connection displays Horizon BCBSNJ’s code auditing rules for various code combinations and the corresponding clinical rationale.

To access Clear Claim Connection, log on to, select Horizon BCBSNJ from the My Health Plans menu:

  • Mouse over Claim Management and select Clear Claim Connection.
  • Within Clear Claim Connection, enter the required data to obtain the appropriate code auditing results. Clear Claim Connection will provide you with the ability to identify Horizon BCBSNJ’s code auditing rules.

Note: This auditing reference tool will provide results that reflect the reimbursement policies on the current date, not necessarily the service date. Displayed results are not a guarantee of how your actual claim will be processed. Claim reimbursement is subject to member eligibility and all member and group benefit limitations, conditions and exclusions.


The Eligibility and Benefits Inquiry transaction allows you to access eligibility and benefits information for active Horizon BCBSNJ members. The Eligibility & Benefits Detail screen displays:

  • Current Primary Care Provider Information (if applicable)
  • Plan information
  • Patient’s Gender and Date of Birth
  • Patient’s relationship to Subscriber
  • Group Information (if applicable)
  • Service Type information section
  • Benefit Accumulation
  • Prior Authorization Indicator
  • Status (identifies subsidized members who are delinquent on their premium payment)

Service Type Information Section

The Service Type Information section displays various service type product information for the patient.

Benefit Accumulation

Making arrangements to collect amounts that will be applied to a member’s deductible requires that you validate the amount applied to the members’ deductible to date. To view the deductible amount a member has satisfied to date within Eligibility & Benefits Inquiry.

  • Enter the requested Subscriber Information and click Search. Note: In rare cases, you may see a listing of dependents in instances when multiple matches are found.
  • From the list of dependents that displays, double click the member in question.
  • The annual deductible amount as well as the amount remaining to be satisfied will be displayed in the Health Benefit Plan Coverage section.

Remember that the deductible information displayed on NaviNet is based on finalized claims as of the date that NaviNet is accessed. Claims that are processed or adjusted following your review of this information and prior to the processing of claims to be submitted might alter the patient’s true deductible liability.

Health care fraud, waste and abuse are national problems that affect us all. Horizon BCBSNJ takes health care fraud, waste and abuse seriously. Each day, our Special Investigations works to uncover fraudulent activities and recover monies paid as a result of such activity. Health care fraud, waste and abuse can take many forms, including:

  • Performing unnecessary health care services or procedures for the sole purpose of producing more billings and insurance payments
  • Falsifying a patient’s diagnosis to justify tests, surgeries or other procedures
  • Supplying durable medical equipment that patients do not need

If you suspect that a member, health care professional or employee of a health care facility is committing fraud, call our Special Investigations Anti-Fraud Hotline at 1-800-624-2048 or send documents and/or inquiries to:

Special Investigations
PO Box 200145
Newark, NJ 07102-0303

As a Medicare Advantage and Medicare Part D plan sponsor, we also work closely with the Centers for Medicare & Medicaid Services (CMS) to investigate and prosecute all instances of fraud, waste and abuse involving those lines of business. Our dedicated Medicare Advantage and Medicare Part D Fraud, Waste and Abuse Hotline is 1-888-889-2231.

HorizonNet 2000

HorizonNet 2000 (HNET) has been identified as an impacted software application in accordance with Health Insurance Portability and Accountability Act of 1996 (HIPAA) Version 5010 regulations. After a detailed impact analysis and consideration of several remediation options, Horizon BCBSNJ will only update HNET 2000’s Notice of Admission – Request for Authorization transactions. We reached this decision after considering several factors including development resources, costs and the fact that HNET 2000’s transactions are available to you through other platforms (our Online Services and various software vendors).

If you have general questions about HNET 2000 or want a copy of Horizon BCBSNJ’s approved Trading Partners list, call our EDI Service Desk at 1-888-334-9242, Monday through Friday, between 7 a.m. and 6 p.m., ET.
