Billing deadline for providers under North Carolina workers' compensation law
Under North Carolina workers' compensation statutes, a health care provider must file a bill for services rendered to an injured employee within 90 days of the date of service. The deadline is strict; missing it can result in the claim being denied unless a valid extension is granted by the North Carolina Department of Insurance (NCDOI) or the employer's insurer.

How the 90‑day clock starts
The countdown begins on the day the provider delivers the service—whether it is an office visit, diagnostic test, surgery, or physical therapy session. The date is recorded on the provider's claim form and must match the date on the patient's medical record. If the service spans multiple days (e.g., a multi‑day hospital stay), the deadline is calculated from the last day of treatment.
Exceptions and extensions
North Carolina law allows limited extensions when the provider can demonstrate a legitimate reason for the delay. Common grounds include:
- Patient's inability to sign or provide required documentation due to ongoing medical issues.
- Provider's internal processing backlog caused by a natural disaster or system outage.
- Delayed receipt of the employer's workers' compensation claim number.
To obtain an extension, the provider must submit a written request to the insurer or the NCDOI before the original 90‑day deadline expires. The request should detail the reason for the delay and include supporting evidence. Approval is at the insurer's discretion and is not guaranteed.
Consequences of missing the deadline
If a bill is submitted after the 90‑day period without an approved extension, the insurer may reject the claim outright. The provider then faces the following outcomes:
- Loss of reimbursement for the services rendered.
- Potential need to pursue a separate civil action for payment, which is often more time‑consuming and costly.
- Impact on the provider's relationship with the employer's insurance carrier, possibly affecting future referrals.
In rare cases, the insurer may consider a late claim if the provider can prove extraordinary circumstances, but this is the exception rather than the rule.
Best practices for timely submission
To avoid missing the deadline, providers should adopt these workflow safeguards:
- Enter the service date and claim details into the billing system immediately after each encounter.
- Maintain a calendar alert set for 75 days post‑service as a reminder to review pending claims.
- Verify the workers' compensation claim number before filing; request it from the employer's HR or the insurer promptly.
- Keep electronic copies of all medical records and authorizations to expedite the billing process.
Comparison of billing deadlines across states
| State | Standard billing deadline | Extension provisions |
|---|---|---|
| North Carolina | 90 days from date of service | Extensions possible with written request; approval discretionary |
| South Carolina | 120 days | Automatic 30‑day extension if claim number not provided |
| Virginia | 30 days | Strict; no extensions except for insurer error |
Key takeaways
North Carolina mandates a 90‑day window for providers to submit workers' compensation bills, starting on the service date. Extensions are not automatic and must be requested before the deadline, supported by documented reasons. Missing the deadline typically leads to claim denial and loss of payment, so proactive billing practices are essential for compliance and revenue protection.
