Missing a timely filing deadline is one of the fastest ways for healthcare providers to lose revenue. Even when services are medically necessary and properly documented, claims submitted after the payer’s filing deadline are often denied with little opportunity for reimbursement.
For providers working with Anthem, now operating under the Elevance Health brand, understanding timely filing requirements is critical to maintaining a healthy revenue cycle.
In this 2026 guide, we’ll explain Anthem’s timely filing limits, common denial reasons, best practices for avoiding filing deadline issues, and how Nexa Digital Pro helps healthcare organizations maximize collections and reduce revenue loss.
A timely filing limit is the maximum amount of time a healthcare provider has to submit a claim after the date of service.
If a claim is submitted after the filing deadline, the insurance payer may deny payment regardless of medical necessity or coverage eligibility. Timely filing requirements are an essential part of Revenue Cycle Management (RCM) and directly impact cash flow and reimbursement rates.
For many Anthem commercial plans, the standard timely filing limit for participating providers is generally 90 days from the date of service. However, filing limits can vary by state, employer group, Medicaid plan, Medicare Advantage plan, and provider contract. Providers should always verify filing requirements within their specific Anthem provider agreement.
| Claim Type | Typical Filing Window |
|---|---|
| Initial Claims | 90 Days from Date of Service |
| Secondary Claims | 90 Days from Primary EOB |
| Corrected Claims | Varies by Plan |
| Reconsiderations | Often up to 180 Days |
| Formal Appeals | Varies by State and Plan |
Always verify deadlines through the Anthem provider portal, provider manual, or payer-specific contract documentation.

Many practices lose thousands of dollars annually due to preventable timely filing denials.
New providers often begin seeing patients before credentialing is fully completed, creating claim submission delays.
Incorrect member information can delay claim processing and resubmission.
Incomplete documentation may prevent timely claim submission.
Unresolved claim rejections can push claims beyond filing deadlines.
Many practices lack dedicated billing resources to monitor claim aging effectively.
Electronic claims are processed faster and provide submission tracking documentation.
Review aging reports weekly to identify claims approaching filing deadlines.
Correct rejected claims immediately.
