In Texas, a medical provider generally has until the first day of the 11th month after your date of service to send you a bill. If the bill goes unpaid, the provider then has four years from when payment became due to file a lawsuit to collect. Miss either deadline and the provider loses important rights: the first cuts off the ability to demand payment at all, and the second cuts off the ability to sue you for it.
The 11-Month Billing Deadline
Chapter 146 of the Texas Civil Practice and Remedies Code requires a healthcare provider to submit a bill no later than the first day of the 11th month after services were provided.1State of Texas. Texas Civil Practice and Remedies Code 146.002 – Timely Billing Required It applies whether the provider bills you directly or bills your insurance company. So if you had a procedure on January 15, the provider needs to get a bill out by November 1 of that same year.
A provider that misses this window loses the right to collect the debt. That is a stricter consequence than the lawsuit deadline discussed below, because it does not just block litigation — it eliminates the provider’s ability to demand payment. Most providers bill within weeks, so this rule mainly catches administrative errors and billing backlogs. But if a bill arrives ten or eleven months after your visit, check the dates carefully before you pay anything.
The Four-Year Deadline To Sue
Even when a provider bills you on time, they cannot wait forever to enforce the debt. Texas gives creditors four years to file a lawsuit for an unpaid debt.2State of Texas. Texas Civil Practice and Remedies Code 16.004 – Four-Year Limitations Period Medical bills fall under this rule because receiving treatment creates an obligation to pay, essentially a contract even when nothing was signed.
The four-year clock starts when the cause of action “accrues,” which in debt cases generally means when payment was due and you did not make it. That is different from the date of service. If a provider sends you a bill in March with a due date of April 15, the four-year countdown likely starts on April 15, not the day you walked into the office. After four years pass without a lawsuit, the debt is “time-barred,” and the provider loses the legal right to use the courts to force you to pay.2State of Texas. Texas Civil Practice and Remedies Code 16.004 – Four-Year Limitations Period
A provider or collection agency can still call or send letters after those four years. The debt does not vanish; it just becomes unenforceable in court. That distinction matters, because some people pay time-barred debts out of confusion or pressure when they no longer have a legal obligation to do so.
Partial Payments Do Not Restart the Clock
Before 2019, making even a small payment on an old medical bill could reset the four-year statute of limitations, effectively giving the provider a fresh window to sue. Texas closed that loophole. Under the Texas Finance Code, a payment, written acknowledgment, or other activity on a consumer debt no longer revives an expired statute of limitations.3State of Texas. Texas Finance Code 392.307 – Collection of Certain Consumer Debts Barred The change took effect September 1, 2019, and applies to debt buyers and third-party collectors.
This matters because a common collection tactic involves persuading someone to make a token “good faith” payment on a very old debt, which historically restarted the clock. In Texas, that no longer works. If four years have run, they have run, regardless of what you pay or say afterward.
Why a Bill Might Arrive Late Even Though the Provider Was On Time
If you have health insurance, the timing you see as a patient is often shaped by claim processing between the provider and your insurer. Texas law requires insurance companies to pay or deny a clean claim within 45 days for paper submissions and 30 days for electronic submissions, with financial penalties and interest for missed deadlines. Those requirements come from the prompt payment provisions in Chapters 843 and 1301 of the Texas Insurance Code.
You experience this indirectly. When an insurer takes months to process a claim, the provider may hold off on billing you for your share until the insurer pays its portion. That delay can make it feel like the provider sat on the bill even though the claim was submitted promptly. If a late-looking bill arrives, call your insurer and ask when the claim was processed. That one call often explains the timing and tells you whether the 11-month window was actually missed.
Providers also face their own deadlines for submitting claims to insurers. Medicare requires claims to be filed within one calendar year of the date of service, and claims denied for missing that deadline cannot be appealed. Private insurers set their own timely filing limits, typically 90 days to a year depending on the contract.
What To Do With a Late or Time-Barred Bill
Start with the dates. Compare the date of service against the 11-month billing deadline, and compare the payment due date against the four-year window. If the bill arrived after the 11-month mark, the provider may have lost the right to collect entirely. If more than four years have passed since payment was due, the debt is time-barred and cannot be enforced through a lawsuit.
When a collection agency contacts you about a time-barred debt, federal law is on your side. The Fair Debt Collection Practices Act and its implementing regulation prohibit a debt collector from suing you, or threatening to sue you, to collect a debt that has outlived the statute of limitations.4Consumer Financial Protection Bureau. Fair Debt Collection Practices Act (Regulation F) – Time-Barred Debt This applies to third-party collectors. The original provider collecting its own debts is generally not covered by the FDCPA.
Keep everything in writing. Phone calls are harder to prove and easier to misremember. If you believe a bill is time-barred, say so in a written letter to the collector and request they stop contacting you. Under federal law, a collector must generally honor that request. And if a collector sues you on a time-barred debt anyway, the statute of limitations is an affirmative defense: you have to raise it in your response to the lawsuit. A court will not dismiss the case on its own just because the deadline has passed.
Demand Written Validation of the Debt
Any debt collector that contacts you must send a written validation notice within five days of its first communication. That notice must include the amount of the debt, the name of the original creditor, and a statement that you have 30 days to dispute the debt in writing.5Office of the Law Revision Counsel. 15 USC 1692g – Validation of Debts If you send a written dispute within those 30 days, the collector must stop all collection activity until it mails you verification of the debt or a copy of any judgment.
Disputing in writing is almost always worth doing when an unexpected medical collection notice shows up. It forces the collector to prove the debt is real, that the amount is right, and that they have the right to collect it. Many old medical debts have been sold multiple times, and the current holder may not have adequate documentation. You can also request the name and address of the original creditor if it differs from the collector contacting you.5Office of the Law Revision Counsel. 15 USC 1692g – Validation of Debts
The Two Deadlines Side by Side
The 11-month rule and the four-year rule solve different problems. The 11-month rule limits how long a Texas provider has to send the bill after treatment. Miss it, and the provider cannot collect the money at all. The four-year rule limits how long the provider has to sue after the bill goes unpaid. Miss it, and the courts are closed to the provider, though the debt technically still exists and collectors may still ask you to pay it. Knowing which deadline applies to your situation is what tells you whether you owe the money, whether you can be sued for it, and whether it is worth paying at all.
