BCBS Texas Timely Filing Limit 2026: PPO, HMO, Medicaid and Appeals

By DocMBS Billing Team · Last updated: October 2026

Ask five billers for the BCBS Texas timely filing limit and you may get five answers: 95 days, 180 days or 365 days. They are not all wrong. Blue Cross and Blue Shield of Texas (BCBSTX) uses different deadlines for different plan lines, and a claim filed one day late is not eligible for payment. You also can’t bill the patient for it.

This guide puts every BCBSTX deadline in one place, by plan, with the official source for each. It also covers corrected claims, secondary claims, claim reviews, proof of timely filing and how to fix a CO-29 denial.

BCBS Texas Timely Filing Limit by Plan (2026)

Start by checking the member’s ID card. The plan name and network on the card tell you which deadline applies. Then use this table.

Why the BCBS Texas Deadlines Differ (and the Texas 95-Day Law)

Texas law sets a baseline. Under Texas Insurance Code §1301.102, a physician or provider must submit a claim to a PPO insurer by the 95th day after the service. If they don’t, they forfeit the right to payment. A similar rule applies to HMOs.

The same law lets the insurer and the provider extend that window by contract. That is why BCBSTX gives commercial PPO and HMO providers 365 and 180 days. Medicaid works differently. The Texas Medicaid program uses a 95-day rule, and BCBSTX’s STAR, STAR Kids and CHIP plans follow it.

So when you see “BCBS Texas is 95 days” online, that usually refers to Medicaid or to the bare state-law minimum. When you see “365 days,” it refers to Blue Choice PPO. Both are true for their own plan.

Corrected Claims, Secondary Claims and Claim Reviews

The first-claim deadline is only one of several clocks. These are the ones that catch billing teams most often.

BCBSTX reviews commercial claim review requests within 45 days, and you can ask for a second review if you disagree with the first answer. The second review also gets a 45-day decision window.

Worked Example: One Date of Service, Four Deadlines

Example only. A behavioral health practice in Austin sees four BCBSTX patients on March 10, 2026. Each has a different BCBSTX plan. Here is when each claim is due:

Two of those deadlines fall on a weekend. Don’t count on getting an extra business day. Treat the date as a hard stop and file before it.

Now add the follow-up clocks. Say the Blue Choice PPO claim pays short, and the EOP is dated April 20, 2026. Your claim review is due within 180 days of that date, so by October 17, 2026. If the STAR patient also has other insurance and the primary’s RA is dated May 15, 2026, the BCBSTX Medicaid secondary claim is due within 95 days, by August 18, 2026.

Proof of Timely Filing BCBSTX Accepts

If BCBSTX denies a claim as late but you know you filed on time, you need proof. BCBSTX’s claim review rules list these as acceptable:

• Availity Electronic Batch Response (EBR) reports showing BCBSTX accepted the claim
• Texas Department of Insurance (TDI) mail log for paper claims
• Certified mail receipt, but only together with a TDI mail log
• Proof that the claim was filed on time with the wrong BCBSTX division
• BCBSTX documents showing the claim was incomplete or that BCBSTX asked for more information
• The primary carrier’s EOB showing you filed on time with the primary

A screenshot of your practice management system is not on that list. A clearinghouse “sent” status is also weak proof. What matters is the payer-level acceptance report.

Step-by-Step: How to Never Miss a BCBSTX Deadline

1. Verify eligibility and plan type at check-in. Use Availity to confirm whether the member has PPO, HMO, Medicare Advantage, Medicaid or FEP coverage. Record the plan line in your system.
2. Set a filing deadline per plan line. Build rules in your billing system: 95, 180 or 365 days, or the FEP year-end date.
3. Submit electronically within 7 days of service. Use the right payer ID: 84980 for PPO and HMO, 66002 for Medicaid.
4. Work clearinghouse rejections every day. A rejected claim never reached BCBSTX, so the clock is still running.
5. Save the Availity EBR report for every batch. Store it where your team can find it in a year.
6. Check claim status at 30 days. If BCBSTX has no record of the claim, resubmit right away and keep the proof.
7. Track follow-up deadlines. Put the 180-day commercial review date and the 120-day Medicaid appeal date on every denied or short-paid claim.
8. Run a weekly aging report by deadline, not just by days in AR. Any BCBSTX claim within 30 days of its limit gets worked first.

Common Denials and How to Fix Them

If timely filing write-offs keep showing up in your BCBSTX AR, the problem is usually in the process, not the payer. Our medical billing and denial management services are built to catch these claims before they age out.

Behavioral Health and Home Health Claims in Texas

Behavioral health: Many Texas therapy and ABA practices see a mix of BCBSTX PPO, HMO and STAR Kids patients. The 95-day Medicaid limit is much shorter than the commercial limits, so a STAR Kids claim held for a missing authorization can expire long before a PPO claim from the same day. Track Medicaid claims on their own work queue.

Home health: Home health agencies often bill after the end of a period of care. That uses up days from the filing window before the claim is even created. On BCBSTX Medicaid and Medicare Advantage plans, build that billing delay into your deadline tracking.

FAQs

What is the BCBS Texas timely filing limit?

It depends on the plan. Blue Choice PPO claims must be filed within 365 days of the date of service. Blue Advantage HMO and Blue Cross Medicare Advantage HMO claims have 180 days. Medicaid STAR, STAR Kids and CHIP claims have 95 days. FEP claims are due by December 31 of the year after the service.

Is the BCBS Texas timely filing limit 95 days?

Only for some plans. The 95-day limit applies to BCBSTX Medicaid STAR, STAR Kids and CHIP. It is also the baseline in Texas Insurance Code §1301.102, but contracts can extend it. BCBSTX gives Blue Choice PPO providers 365 days and Blue Advantage HMO providers 180 days.

What is the BCBSTX appeal deadline?

For commercial plans, request a claim review within 180 days of the EOP check date or Provider Claims Summary date. For Medicaid STAR, STAR Kids and CHIP, submit claim appeals within 120 calendar days from receipt of the remittance advice. Member-level medical necessity appeals have their own timelines.

How long do I have to file a secondary claim with BCBS Texas Medicaid?

BCBSTX must receive Medicaid COB claims within 95 days from the date on the other carrier’s remittance advice or denial letter. Attach the primary payer’s RA or EOB. For commercial plans, the primary EOB serves as proof that you filed on time with the primary.

What counts as proof of timely filing for BCBSTX?

BCBSTX accepts Availity Electronic Batch Response reports, a TDI mail log, a certified mail receipt with a TDI mail log, proof you filed with the wrong BCBSTX division, BCBSTX requests for more information and the primary carrier’s EOB showing timely filing. Practice software screenshots are not on the list.

Can I bill the patient if I miss the BCBS Texas filing deadline?

No. BCBSTX says providers may not seek payment from the member for claims submitted after the filing deadline. That applies to the PPO, HMO and Medicaid plans. A missed deadline usually becomes a write-off unless you can prove the claim was filed on time.

What is the BCBSTX payer ID?

Blue Choice PPO and Blue Advantage HMO claims use electronic payer ID 84980. BCBSTX Medicaid STAR, STAR Kids and CHIP claims use payer ID 66002. Always confirm the payer ID with your clearinghouse, because some plans and out-of-state Blue members route differently.
