Carelon Behavioral Health Timely Filing Limit (2026): Formerly Beacon Health Options

A behavioral health claim that arrives one day past the filing deadline gets denied the same as one that was never submitted and that denial, reason code CO-29, is one of the harder ones to reverse. The problem most billing teams run into with Carelon Behavioral Health isn't finding a number; it's assuming one number applies everywhere. It doesn't.
Carelon's own Out-of-Network Provider Guide sets a default of 90 calendar days from the date of service or discharge but explicitly says that default gives way to whatever a specific Provider Manual or state requirement says instead. A state Medicaid carve-out, a commercial plan, and an out-of-network contract can each land on a different deadline. This guide breaks down what's actually documented, what still needs verification on your end, and what to do if a claim already got denied.
Quick Answer: What Is the Carelon Timely Filing Limit in 2026?
There is no single universal Carelon Behavioral Health timely filing limit. The most commonly cited default is 90 days from the date of service or discharge, but the actual deadline depends on the member's health plan, state, and your provider agreement — some contracts use 95 days, and state Medicaid manuals often set their own explicit number.
Question | Answer |
Does Carelon have one universal filing limit? | No. It depends on the health plan, state, and your specific provider agreement. |
What's a commonly cited default? | Carelon's Out-of-Network Provider Guide cites 90 calendar days from date of service or discharge as a default, unless a Provider Manual or state-specific requirement says otherwise. |
What determines the actual deadline? | The member's health plan, state Medicaid or commercial contract terms, and your specific Carelon provider agreement. |
What should providers verify? | Their applicable provider manual, state-specific supplement, and remittance/EOB instructions before assuming any single number applies. |
What happens if a claim is late? | It's typically denied with reason code CO-29 ("timely filing limit expired"), which is difficult but not always impossible to overturn. |
Don't Make This Billing Mistake Don't assume a timely-filing number from an old Beacon Health Options document, a competitor's blog post, or a different state's manual automatically applies to your Carelon claim in 2026. Verify the health plan, state, and current provider agreement before you rely on any specific day count. |
2026 Timely Filing Requirements by Scenario
Numbers above are drawn from Carelon's own published Out-of-Network Provider Guide, a Carelon state-specific provider manual (Pennsylvania), and Carelon's official waiver request form. Always confirm against the manual and remittance instructions that apply to your specific claim.
Is Carelon Behavioral Health the Same as Beacon Health Options?
Yes, in the sense that matters for billing. Beacon Health Options was the organization's former name; Carelon Behavioral Health is the current brand. Carelon's own materials acknowledge that some provider documents were originally developed under the Beacon name and may still reference it. If your billing team is working from an old Beacon manual, a legacy Beacon payer ID, or a bookmarked policy page, re-verify it against current Carelon resources — payer IDs and specific requirements have been known to change during the rebrand.
Why Timely Filing Actually Matters
A missed deadline doesn't just cost one claim. It sets off a chain: Late Claim → Timely Filing Denial (CO-29) → Rework → Waiver or Exception Review → Delayed or Lost Revenue. Each step adds staff time before you even know whether the revenue is recoverable, and a pattern of timely-filing denials is one of the more preventable sources of aging A/R in a behavioral health billing operation.
What Actually Counts as the Filing Date?
Providers should understand the difference between three distinct events, since only one of them is likely to satisfy a payer's filing requirement:
● Submitted — your system or clearinghouse sent the claim
● Accepted — the clearinghouse or payer's EDI system acknowledged the claim (a 999 or 277CA)
● Received/adjudicated — Carelon has the claim in its system and is processing it
A clearinghouse accepting a claim is not automatically proof that Carelon received it — treat clearinghouse acceptance as one piece of evidence, not a guarantee, and keep the actual acknowledgment on file.
Common Carelon Timely-Filing Denial Reasons
Carelon manages behavioral health benefits on behalf of other plans, so a member's card may say Anthem or a state Medicaid program while their behavioral health benefit is carved out to Carelon. That structure is exactly why misrouted claims — sent to the medical payer ID instead of Carelon's — are one of the most common root causes behind what looks like a timely filing problem.

What to Do After a Timely-Filing Denial
Step 1 — Verify the applicable filing limit: confirm which plan, state, and provider agreement actually governs this claim.
Step 2 — Confirm the original submission date: pull the claim from your billing system, not just memory.
Step 3 — Review clearinghouse acceptance/rejection: locate the 999 or 277CA acknowledgment, or find out why it's missing.
Step 4 — Check payer claim history: verify through the Carelon provider portal whether the claim was ever received.
Step 5 — Determine if a waiver or exception applies: Carelon has published waiver request forms for specific circumstances.
Step 6 — Gather supporting documentation: acceptance confirmations, EOPs, and any written contact from Carelon during the filing window.
Step 7 — Submit the appropriate request: follow the specific dispute or waiver process for that plan — commonly through Availity or a written Provider Claims-Based Dispute Resolution Request.
Step 8 — Track the outcome: log the resolution so recurring patterns get flagged instead of relitigated claim by claim.
Following these steps improves your odds of a fair review — it doesn't guarantee a denied claim gets overturned.

Could Your Claim Be at Risk? A Quick Self-Check
Question | Yes | No |
Was the claim submitted within the applicable deadline for this specific plan? | ☐ | ☐ |
Did the clearinghouse show an acceptance (999/277CA), not just a submission? | ☐ | ☐ |
Does Carelon's system show the claim as received, not just sent? | ☐ | ☐ |
Was the patient eligible with Carelon on the date of service? | ☐ | ☐ |
Was required prior authorization obtained and matched to the claim? | ☐ | ☐ |
Was the claim sent to the correct Carelon-specific payer ID, not a medical payer ID? | ☐ | ☐ |
If you answered "No" to any question, investigate before assuming it's simply a timely-filing issue — a misrouted payer ID or a missed authorization can look identical to a late claim at first glance.
How an RCM Team Can Help
Timely-filing problems are usually easier to prevent than to recover from. An experienced RCM team can help behavioral health practices with eligibility verification, authorization tracking, claim submission and acceptance monitoring, rejection management, denial management, A/R follow-up, and appeals and reconsiderations — catching a misrouted payer ID or a missing authorization before it turns into a filing-limit denial weeks later.
Our RCM team at Sirius Solutions Global works alongside behavioral health billing staff on exactly these workflows, without guaranteeing a specific outcome on any individual claim.
Frequently Asked Questions
Q: What is the Carelon Behavioral Health timely filing limit in 2026?
There isn't one universal number. Carelon's default Out-of-Network guide cites 90 days from DOS or discharge, but specific plans, states, and contracts can set a different deadline — verify against your applicable manual.
Q: Is Carelon Behavioral Health the same as Beacon Health Options?
Beacon Health Options is the former name; Carelon Behavioral Health is the current organization. Some legacy documents and payer IDs may still reference Beacon and should be re-verified.
Q: Does Carelon have one standard timely filing limit?
No. Carelon's own materials tie the deadline to the specific health plan, state, and provider agreement rather than a single fixed number.
Q: Does the timely filing limit vary by state?
Yes. State Medicaid behavioral health carve-outs commonly publish their own explicit filing deadline in a state-specific provider manual.
Q: What happens if a Carelon claim is submitted late?
It's typically denied with reason code CO-29 for exceeding the timely filing limit. A documented waiver or exception may apply in limited circumstances.
Q: How can I prove that a claim was submitted on time?
Keep the clearinghouse or Availity submission confirmation and the EDI acknowledgment (999 or 277CA) — clearinghouse acceptance alone isn't automatic proof of payer receipt.
Q: What should I do if Carelon denies my claim for timely filing?
Verify the applicable deadline, confirm your original submission date and acceptance records, and submit the correct dispute or waiver request for that specific plan.
Q: Are corrected claims subject to the same filing requirements?
Follow the payer-specific resubmission instructions for corrected claims — a correction doesn't automatically restart the filing clock.
Q: Where can providers verify Carelon claim submission requirements?
Through the applicable Carelon provider handbook, state-specific manual, and forms available at carelonbehavioralhealth.com/providers/resources.
Q: Can an RCM company help prevent timely-filing denials?
Yes — by monitoring eligibility, authorizations, and claim acceptance status early enough to catch problems before the filing window closes.
