Aetna Texas Timely Filing Limit: 95-Day Rule Explained

The Aetna Texas timely filing limit for most fully insured commercial claims is 95 days from the date of service, set by Texas law, unless your provider contract allows longer. Institutional claims count from discharge, and secondary claims count from the primary payer’s decision. Self-funded and Medicare Advantage plans follow their own contract terms instead.

In most states, a late commercial claim is a denial you can often fight. Texas uses a stronger word: forfeit. Miss day 95 on a fully insured Aetna claim, and the right to payment can disappear. This guide explains where the 95-day rule comes from, when the clock starts, and which Aetna plans it covers. It also explains Texas prompt pay penalties and what to do when a timely claim is wrongly denied. A ten-question check-up near the end shows how exposed your workflow is today.

Source labels: “Published standard” means Texas statute or TDI regulation sets the rule. “Payer policy” means Aetna publishes it. “Illustrative target” is a practical internal goal from general industry practice; no agency or payer mandates it. Confirm your own contract before relying on any date.

Why Texas Sets the Aetna Deadline at 95 Days?

What the law actually says?

Texas wrote the deadline into law rather than leaving it to payers. Under 28 TAC §21.2806, a physician or provider must submit a claim by the 95th day after delivering care. The Insurance Code sets the same rule for HMOs and preferred provider plans. A provider who misses the deadline forfeits payment, unless a certified catastrophic event caused the delay. That makes timely filing in Texas a legal condition of payment on fully insured plans. The regulation also lets both parties extend the window by contract, but never shorten it.

How Aetna’s Texas policy lines up?

Industry billing sources report that Aetna aligned its Texas filing window with the state’s 95-day rule on May 1, 2023. That change reportedly did not override provider agreements that already had their own filing terms. So read your contract, since some Texas agreements allow longer windows. Whatever number applies, set your internal deadline well inside it to leave room for fixing rejections.

Worked Example 1 — Professional Claim Deadline Formula: Filing deadline = Date of service + 95 days Scenario: Office visit on July 7, 2026. Day 95 falls on Saturday, October 10, 2026. Tip: The rule says “not later than the 95th day,” so transmit electronically before the weekend.

The catastrophic event exception

Texas excuses late filing only when a catastrophic event caused it. Think of a fire, flood, or major storm that disrupts normal business operations. According to TDI’s prompt pay guidance, the affected provider must contact TDI within five days of the disruption. The request goes to PromptPay@tdi.texas.gov and must describe the event, the dates, and each affected location. Once TDI approves, the deadlines are paused for the disruption period. Routine problems, such as staff turnover or a software upgrade, do not qualify.

When the 95-Day Countdown Begins?

The day count stays at 95, but the starting event changes with the claim type. Choosing the wrong start date is one of the most common Texas errors. For hospitals and other institutional providers, the count begins at discharge, so a long stay does not eat into the window. Under coordination of benefits, the secondary clock starts when you receive the primary payer’s payment or denial. Record the date that notice arrived, not just the EOB print date.

Worked Example 2 — Institutional and Secondary Deadlines Formula: Deadline = Starting event + 95 days Inpatient discharge on August 20, 2026 → claim due November 23, 2026. Primary payer’s denial received September 1, 2026 → Aetna secondary claim due December 5, 2026.

Which Aetna Plans Follow Texas Rules?

Fully insured versus self-funded coverage

The 95-day rule and prompt pay protections apply to fully insured plans regulated by the Texas Department of Insurance. Aetna also administers many self-funded employer plans, where the employer carries the risk. Those plans fall mainly under ERISA, so Texas prompt pay generally does not reach them. Filing windows then come from your Aetna agreement and the plan terms, which may differ from 95 days. Record the funding type at eligibility, because the cards often look identical. If mixed-up plan types have already caused denials, structured denial management support can help sort them out.

Medicaid and Medicare Advantage lines

Aetna Better Health of Texas, the Medicaid and CHIP plan, lists 95 days from the date of service. For coordination of benefits claims, it allows 95 days from the EOB. Aetna Medicare Advantage claims fall under federal rules and your Medicare Advantage agreement, not the Texas Insurance Code. Contracted providers should use the filing period in their agreement. Non-contracted providers should confirm the window with Aetna, since published figures vary.

What Aetna Owes When a Clean Claim Pays Late?

Texas pairs its strict filing rule with strict payment deadlines. For contracted providers on fully insured plans, a clean claim must be paid within 30 days electronically or 45 days on paper. When a carrier misses that deadline, the Texas Medical Association explains that it owes the contracted rate plus a tiered penalty. The penalty equals 50% of billed charges minus the contracted rate for payments 1–45 days late. It rises to 100% for 46–90 days late. After that, 18% annual interest accrues on the penalty from the date payment was due. Dollar caps apply to each tier.

Worked Example 3 — Prompt Pay Penalty Formula: Penalty = Tier percentage × (Billed charges − Contracted rate) Scenario: Billed $1,000; contracted rate $400; difference $600; electronic clean claim. Paid 20 days late (Tier 1): 0.50 × $600 = $300. Paid 60 days late (Tier 2): 1.00 × $600 = $600. Paid 100 days late (Tier 3): $600 plus 18% × $600 × 100/365 = about $29.59 in interest.

When Aetna denies a claim you filed on time?

Sometimes a claim arrives on time but still gets denied as late. Don’t resubmit it as a new claim, because the new receipt date works against you. Instead, file a reconsideration or appeal with proof of timely submission attached. The strongest proof is a clearinghouse acceptance report or a payer receipt confirmation. Aetna’s published dispute window is 180 days from the decision where no state exception applies. For fully insured plans, a provider can also file a prompt pay complaint with TDI.

Watching Aetna Timeliness Inside Your Practice

The statute tells you when payment is lost, but internal measures warn you weeks earlier. The two most useful are days to bill and the share of Aetna claims accepted by day 45. Both targets in the table above are illustrative goals, not Aetna or TDI benchmarks. Actual figures vary by specialty, product mix, and staffing, so verify them against your own data. They fit alongside the broader medical billing KPIs you may already track.

Worked Example 4 — Day-45 Acceptance Rate Formula: Claims accepted by day 45 ÷ Total Aetna claims × 100 Scenario: 441 of 450 claims accepted = 98%, just under the 99% illustrative goal. Exposure: 9 late claims × $150 average = $1,350 that could be lost after day 95.

How a blended rate hides one weak product?

Illustrative scenario (not an actual client record): a Houston multi-specialty group bills three Aetna lines. Its blended on-time rate is 95.8%, which looks fine. Split by product, the self-funded plans sit at 88%, because staff assumed the statutory 95 days applied everywhere. Those plans actually ran on a shorter 90-day contract window. Aging balances like these deserve dedicated accounts receivable management attention.

Illustrative product split

Aetna Product (Illustrative)	Claims	On Time	Rate
Fully insured PPO	200	199	99.5%
Self-funded (90-day contract)	150	132	88.0%
Aetna Better Health of Texas	150	148	98.7%
Blended	500	479	95.8%

Comparing Your Numbers Fairly

The 95-day rule and payment deadlines are legal requirements, so they apply to every provider equally. Internal targets work differently and only mean something when compared like-for-like. Compare the same Aetna product, a similar service mix, a comparable practice size, and the same reporting period. One missed target is a signal to investigate, not a verdict on your team.

How Soon Fixes Usually Show Results?

These are general planning ranges, not guarantees. Backlog size, product mix, and staffing will change them for any practice.

Fix	Early Signs	Steadier Results
Due dates keyed to claim type and funding type	Within one billing cycle	Within a quarter
Daily rejection review before day 30	Within a few weeks	Within a quarter
Prompt pay penalty audit on late payments	Within one to two months	Over two quarters

Key Takeaways

• Texas law requires fully insured claims by day 95, or payment is forfeited (published standard).
• Institutional claims start at discharge; secondary claims start when the primary notice arrives.
• A catastrophic event requires a TDI extension request within five days of the disruption.
• Self-funded, Medicare Advantage, and Aetna Better Health plans follow their own rules.
• Two to five days to bill and 99%+ acceptance by day 45 are illustrative goals, not mandates.

Aetna Texas Filing Check-Up: 10 Questions

Answer each with yes or no, then count your yes answers.

1. Do you know whether your Aetna agreement extends the 95-day window?
2. Do you record whether each Aetna plan is fully insured or self-funded?
3. Do institutional claims use the discharge date as the start?
4. Do you log the date primary payer notices arrive?
5. Is your average days to bill five days or fewer?
6. Were 99% or more of Aetna claims accepted by day 45 last month?
7. Did you have zero Aetna claims lost to timely filing last quarter?
8. Do you check late fully insured payments for prompt pay penalties?
9. Do you appeal timely-filing denials with clearinghouse proof instead of resubmitting?
10. Do you track Aetna Better Health and Medicare Advantage on separate calendars?

9–10 yes: Strong control; review monthly. 6–8 yes: Gaps exist; fix the “no” items this quarter. 0–5 yes: Revenue is likely slipping now; review every Aetna claim older than 45 days this week.

Signs Your Team Needs Outside Help

Many practices handle these deadlines well in-house. These signals suggest your current process has reached its limit:

• Aetna claims routinely go out more than two weeks after the visit.
• Nobody can say which Aetna members have self-funded coverage.
• Late payments arrive without penalties, and no one notices.
• Any claim was lost to the 95-day rule in the past year.

Good outside support should set due dates by claim type, capture funding type at eligibility, and audit late payments. EON MED SOLUTIONS works this way, assigning a dedicated agent to each provider for medical billing, coding, credentialing, and denial follow-up. Results depend on each practice’s situation.

Expert Opinion

The Aetna Texas timely filing limit rests on state law, not just payer policy. Ninety-five days is the standard for fully insured claims, and the start date depends on claim type. On the other side, Texas prompt pay penalties give contracted providers real leverage when Aetna pays late.

To be clear about sources: the 95-day rule, forfeiture, the catastrophic event process, the 30/45-day payment deadlines, and the penalty tiers are published Texas standards. Aetna’s 2023 alignment, Aetna Better Health’s 95-day rule, and the 180-day dispute window are payer policies. Days to bill, the day-45 goal, and the improvement ranges are illustrative targets to adapt to your own data.

Frequently Asked Questions
