Texas Medical Billing Laws: What Providers Need to Know in 2026
TL;DR: Texas providers must follow three core medical billing laws: a timely billing rule that gives you until the 1st of the 11th month after service to bill the patient, SB 490’s itemized bill requirement before any debt collection, and SB 1264’s balance billing ban for state-regulated plans (extended to ground ambulance by SB 2476). Miss any of them and you lose the right to collect. Build the rules into your workflow, don’t bolt them on.
Texas medical billing laws are stricter than most providers realize, and the penalties for getting them wrong hit your cash flow directly. One billing industry report notes that more than 10% of Texas providers violate the state’s timely billing rule each year, forfeiting payment they had every right to collect. The fix isn’t more effort. It’s understanding what the state actually requires.
This guide walks through the three laws that matter most: timely billing, itemized billing under SB 490, and balance billing protections under SB 1264 and the newer SB 2476. You’ll see what each one requires, who it applies to, and what happens when you don’t comply. If you run a Texas practice, manage RCM for one, or outsource your billing, this is the rulebook your workflow needs to match.
What Are the Main Texas Medical Billing Laws Providers Must Follow?
Texas providers must follow three primary billing laws: the timely billing rule under Chapter 146 of the Health and Safety Code, the itemized billing requirement under SB 490 (Chapter 185), and the balance billing protections under SB 1264 and SB 2476. Workers’ comp claims also fall under a separate electronic billing mandate.
These rules stack. A bill can be timely and still violate SB 490 if it isn’t itemized. A bill can be itemized and still violate SB 1264 if it tries to balance bill a protected patient. Treat them as a single compliance layer, not three separate boxes to tick.
Workers’ compensation adds one more piece. Texas Labor Code §408.0251 requires providers and carriers to submit and process medical bills electronically for work-injury claims, with limited paper exceptions. If you bill workers’ comp, your software has to handle it.

What Is the Texas Timely Billing Law?
The Texas timely billing law requires providers to send a bill to the patient no later than the first day of the 11th month after the service was provided. If you miss that deadline, you can’t collect those charges from the patient or anyone connected to them. The rule lives in Health and Safety Code §§146.002 and 146.003.
The deadline applies whether you’re billing the patient directly or going through Medicare, Medicaid, or a commercial carrier. If your contract with a third-party payer sets an earlier deadline, that one controls. If it doesn’t, the 11th-month rule still applies as the outer limit.
There’s also a four-year statute of limitations on suing to collect medical debt. So even if you bill in time, you have to take legal action within four years of the date of service if it comes to that.
Practical example: a patient is seen on March 15, 2026. You have until February 1, 2027, to send the bill. Send it February 2, and you’ve lost the right to collect for any charges the patient would have been reimbursed for or wouldn’t have owed if you’d billed on time.
SB 490 and the Itemized Billing Requirement
SB 490 took effect September 1, 2023, and added a new compliance step before you can collect a dollar from a patient. The law sits in the new Subtitle J / Chapter 185 of the Health and Safety Code, and the Texas Health and Human Services Commission enforces it.
The rule is short: if you’re requesting payment from a patient after services were rendered, you must give them a written, itemized bill first. No itemized bill, no collection. Full stop.
The bill must include three things, per the official Senate analysis of SB 490:
- An itemized list of every service and supply provided
- The amount you’ll accept as payment in full for each line
- A plain-language description of each service so the patient understands what it is
If you billed a third-party payer, you also have to disclose the billing codes you submitted and the amounts billed and paid by that payer. Need a refresher on coding? See our [[INTERNAL LINK: place of service codes]] guide.
The timing matters too. You have 30 days from receipt of final payment from a third-party payer to deliver the itemized bill to the patient. For self-pay patients, the itemized bill must go out when you first request payment.
Who does it apply to? The definitions are broad. SB 490 defines a “health care provider” to include any facility licensed to provide care in Texas, including hospitals, with a narrow carve-out for federally qualified health centers. Solo practices, group practices, ASCs, and hospitals are all in scope.
One detail providers often miss: the law explicitly says hospitals must provide the itemized bill before sending the account to collections or pursuing any payment. Selling debt or handing it to a collections agency without an itemized bill on file is a violation.
You can deliver the bill electronically (patient portal, email) as long as the transmission is HIPAA-compliant, since itemized bills contain PHI. Patients also have the right to request an itemized bill at any time, even years later. Build a request workflow now; you’ll need it.
Penalties for non-compliance include disciplinary action from your licensing board, on top of the loss of the right to collect.
How Does Texas Balance Billing Law Affect Out-of-Network Providers?
Texas SB 1264 prohibits out-of-network providers from balance billing patients with state-regulated health plans in three situations: emergency services, services delivered at an in-network facility, and out-of-network diagnostic imaging or lab work tied to an in-network service. Disputes go through TDI’s Independent Dispute Resolution (IDR) process, not the patient.
The law took effect January 1, 2020 and covers patients whose insurance card shows TDI, DOI, or TXI, plus members of ERS, TRS-ActiveCare, and TRS-Care Standard. About 16% of Texans have state-regulated coverage that falls under SB 1264.
For payment, health plans must reimburse out-of-network providers at the “usual and customary rate” and pay clean claims directly to the provider within 30 days for electronic submissions and 45 days for paper. If you disagree with what the plan paid, you don’t bill the patient. You file for IDR. Facilities go through mediation; physicians and other non-facility providers go through arbitration.
There’s a narrow exception. A patient can sign a balance billing waiver, but only when they had a genuine choice between an in-network and out-of-network provider, with the waiver delivered at least 10 business days before the service. The waiver can’t be used in emergencies or when an out-of-network specialist (like an anesthesiologist) is assigned to a case.
If your practice is out-of-network with any major Texas plan, your intake and consent paperwork need to handle this correctly. See our [[INTERNAL LINK: out-of-network credentialing]] guide for the workflow side of this.
One important limit: SB 1264 does not apply to self-funded employer plans (most large-employer coverage), which are governed by federal law. For those patients, the No Surprises Act sets the rules instead.
How Does Texas Balance Billing Law Affect Out-of-Network Providers?
The penalties for violating Texas medical billing laws fall into four buckets: loss of the right to collect, disciplinary action from your licensing board, unfavorable IDR rulings, and reputational damage from patient complaints. None of them are theoretical; each one is built into the statutes.
Timely billing violations are the most direct hit. Miss the 11th-month deadline and you simply can’t collect on amounts the patient would have been reimbursed for, or wouldn’t have owed had you billed on time. The money is gone.
SB 490 violations trigger two consequences. You can’t pursue collection until you deliver a compliant itemized bill, and your licensing board (the Texas Medical Board, Texas Board of Nursing, or whichever applies to you) can open disciplinary proceedings under HHSC enforcement. Disciplinary action stays on your record.
Balance billing violations are heard through TDI’s IDR process. If you billed a protected patient improperly, the patient (or their plan) can flag it, and the dispute outcome usually goes against the provider. Repeated violations invite TDI scrutiny.
Then there’s the reputational layer. Texas state and consumer-protection groups actively publicize providers who balance-bill protected patients, and patient-side organizations are watching. One viral complaint can do more damage than the fine.
A clean denial management process catches most of these issues before they escalate.
How Providers Can Stay Compliant With Texas Medical Billing Laws
Compliance isn’t a one-time project; it’s a set of workflow rules your billing team runs every day. Here’s the practical checklist:
Lock in a timely billing SLA. Every claim and patient bill should leave your office well before the 11th-month deadline. Most efficient practices target 60 to 90 days from date of service for patient bills, which builds in a buffer for payer adjudication and patient questions.
Standardize your itemized bill template. Every patient bill that asks for money post-service should automatically include the SB 490 elements: line-item services, plain-language descriptions, the amount you’ll accept as full payment, and billing codes plus third-party payments where applicable. Build it into your billing software, not a manual step.
Set up a 30-day post-final-payment trigger. The moment a third-party payer’s final payment posts, the clock starts. An automated 30-day reminder keeps you on the SB 490 timeline.
Handle out-of-network status correctly. If you’re OON with a plan that’s regulated by Texas (TDI/DOI/TXI cards, ERS, TRS), don’t balance bill. Send disputes to IDR instead. If you want the option to balance bill a non-emergency patient, deliver the disclosure and waiver at least 10 business days before service.
Submit EMS fee schedules to TDI on time. If you run a ground ambulance service, get your fee schedule on file in the TDI portal so you’re paid at your rate rather than the 325%-of-Medicare fallback.
Move workers’ comp to electronic billing. The Labor Code §408.0251 mandate isn’t optional for most claims.
Train staff and document everything. Every itemized bill delivery, every balance billing waiver, every electronic transmission needs an audit trail. PHI on itemized bills means you also need HIPAA-compliant billing processes for delivery.
If building this in-house is more than your team can carry, outsource your medical billing to a partner with Texas-specific experience.
Conclusion
Texas medical billing laws come down to three things every provider has to get right: bill on time, itemize before you collect, and never balance bill a protected patient. The penalties are simple too: write off the charge, face the licensing board, or lose the dispute. None of those outcomes need to happen if your workflow is built correctly.
The state has tightened these rules steadily since 2019, and the trend isn’t slowing. SB 2476 closed the ground ambulance gap in 2024, and federal updates around the No Surprises Act are still in motion. Audit your billing process this quarter against the three pillars above, fix the gaps, and document the changes. If you’d rather hand it off, partner with a billing service that lives inside these rules every day.
