Horizon BCBSNJ timely filing limit
Short answer
The Horizon BCBSNJ timely filing limit is 180 days from the last date of service for a claim you file under the patient's assignment of benefits, the window New Jersey's claims rule, N.J.A.C. 11:22-3.4, sets for the payers it covers. File later and Horizon may deny or dispute the claim, and you cannot bill the patient for it.
Under the Ensuring Transparency in Prior Authorization Act, in effect since January 1, 2025, you may appeal a claims determination on or before the 90th calendar day after you receive it, and when more than $1,000 is in dispute you may then seek binding arbitration within 90 days of the appeal decision. Compare other payers in the timely filing limits table.

- Appeal

Exceptions the payer allows
A late claim is weighed, not denied on lateness alone
When a claim arrives after 180 days, the rule lets the payer deny or dispute it, but the payer must tell you that payment will turn on five factors you address: good faith use of the payer information the patient gave you, delays caused by coordination of benefits, whether you have a pattern of untimely claims, prejudice to the patient's or provider's rights in the medical necessity review, and the effect on the public. Answer each one in writing.
Asking a court to let you refile
If a claim filed after 180 days is denied in whole or in part, a Superior Court judge may let you refile it when the payer has not been substantially prejudiced. The motion is due within 14 days of the denial notice and needs affidavits showing why the claim was late.
Claims without an assignment of benefits
When you file for a patient who has not assigned benefits to you, the same rule gives you 60 days from the last date of service, not 180. Get the assignment signed at intake so the longer window applies.
Self-funded employer plans
DOBI's claims-handling guidance does not apply to self-funded plans or to policies issued outside New Jersey, and its arbitration program excludes self-funded plans and the State Health Benefits Program. Confirm the plan type on the member's card before you rely on a New Jersey deadline.
What counts as proof of timely filing
- The 277 acknowledgement for each electronic claim, which New Jersey's rule requires a payer to send for every electronically filed claim; the ETPAA requires the acknowledgement within two working days
- If your system cannot receive a 277, the alternative acknowledgement you and the payer agreed on, which the rule requires the payer to set up with you
- Your intake records showing the patient's assignment of benefits and the payer information the patient gave you, the first factor a payer must weigh on a late claim
- For an appeal, the Health Care Provider Application to Appeal a Claim Determination form, carrier-specific or generic, which DOBI Bulletin 10-32 says should be used for claim payment and overpayment recoupment appeals; an appeal not filed on it cannot go to PICPA arbitration
Notes for billers
- A carrier must pay an electronic claim within 30 days and any other claim within 40 days, or tell you within the same period why it is unpaid; an overdue claim bears 12 percent simple interest a year (DOBI Bulletin 24-17).
- A carrier cannot seek repayment of an overpaid claim more than 18 months after the first payment, and a provider cannot seek more for an underpaid claim more than 18 months after the first payment, unless the claim is under appeal or subject to continual claims submission. If you appeal a repayment request within 45 days, the carrier cannot collect it until your appeal rights are used up.
- Arbitration runs through the Program for Independent Claims Payment Arbitration (PICPA), only after the internal appeal is exhausted and only for an appeal filed on the DOBI appeal form. You can combine disputed claims to pass the $1,000 threshold. The arbitrator decides in writing within 30 days of receiving the documents, the decision binds both sides, and a payment owed with interest is due within 10 business days.
- DOBI readopted N.J.A.C. 11:22, the chapter that holds the 180-day rule, effective February 17, 2026, so the rule runs to February 17, 2033. The rule was first adopted in 2001 as N.J.A.C. 11:22-3.6 and moved to 11:22-3.4 in 2011 with no change in text.
- DOBI's examination of Horizon Healthcare Services, Inc. as of December 31, 2020 describes it as doing business as Horizon Blue Cross Blue Shield of New Jersey and operating as a not-for-profit health service corporation domiciled in New Jersey, one of the carrier types the ETPAA covers.
