IC System and Your Texas Lawsuit: Medical Bills, Deadlines and Defenses

IC System (registered in Texas as I C System Inc) is a collection agency, not a debt buyer. Its own website says it collects for original creditors, and most of its clients are health care providers. So if IC System has been calling or writing about a medical bill and you have now been served with court papers, the first question is who the plaintiff actually is. The answer changes what has to be proved and what defenses apply.

Who Is IC System?

IC System's FAQ says it was "founded in 1938" and is "a family-owned, privately held collection agency," licensed or bonded in all 50 states, Guam and Puerto Rico. It also says: "IC System provides collection services to original creditors only." Its health care page states that its "more than 4,000 healthcare clients represent over 70% of our client mix," and its website lists other industries it serves, including utilities, telecommunications, dental and veterinary offices, and government.

For consumers, IC System lists a medical line at 866-628-7811, a line for other inquiries at 800-279-7244, and a language-access line at 1-800-279-9420. Correspondence goes to IC System Correspondence, 444 Highway 96 East, P.O. Box 64378, St. Paul, MN 55164-0378, and disputes to P.O. Box 64319, St. Paul, MN 55164-0319.

Texas Secretary of State bond

Third-party debt collectors must file a surety bond with the Texas Secretary of State (Finance Code § 392.101). On November 3, 2026, the registry showed an active bond for I C System Inc, file 20050100, filed April 20, 2005, at 444 Highway 96 East, St. Paul, Minnesota, issued by Travelers Casualty and Surety Company of America. A 1993 filing was canceled in 2004. Note that searching the registry for "IC System" without the space does not find it.

Texas Debt Law is not affiliated with IC System.

Who Is Actually Suing You?

IC System's website describes collection calls, letters, optional credit reporting for clients, and an optional "Non-Litigation Attorney Referral" service. It does not describe filing lawsuits. In practice that means:

• If the petition names a hospital, clinic or other provider, the provider is suing on its own account through its own lawyer, and any role IC System had was in collecting before suit.
• If the petition names another company as assignee, that company must prove it acquired the account.
• If you have only a letter or call saying you "have been sued," and no citation delivered by a sheriff, constable or process server, check with the court clerk before you do anything else. See how to know if you've really been sued.

Your Answer Deadline

Once you are served, the court's deadline controls:

• Justice court: the end of the 14th day after service (Texas Rule of Civil Procedure 502.5).
• County court at law or district court: 10:00 a.m. on the Monday after 20 days from service (Rule 99(b)).

Our answer deadline calculator will give you the date. Payment arrangements with IC System, or a dispute letter, do not answer the suit.

The Texas Itemized Medical Bill Rule

Since September 1, 2023, Texas Health and Safety Code chapter 185, added by S.B. 490, requires a licensed health care provider that asks a patient for payment to send a written, itemized bill. It must list each service and supply in plain language, any billing codes submitted to an insurer with the amounts billed to and paid by the insurer, and the amount the provider says the patient owes for each item. The bill is due no later than 30 days after the provider receives final payment from a third party such as an insurer.

The key sentence for collection is § 185.002(e): a provider "may not pursue debt collection against a patient" for a service or supply unless it has complied. "Debt collection" has the meaning used in the Texas Debt Collection Act. Federally qualified health centers are excluded. The statute is enforced through licensing discipline and does not expressly create a private lawsuit, and courts have not yet said much about how it applies in collection suits. H.B. 216, effective September 1, 2025, added rules about how itemized bills must be delivered.

What to do with this:

1. Ask the provider in writing for the itemized bill, and keep a copy of your request.
2. Compare it with your insurer's explanation of benefits. Look for charges that should have been paid or adjusted by insurance.
3. If you never received an itemized bill, tell your lawyer. It may bear on whether collection, and a lawsuit, was allowed.

What the Plaintiff Has to Prove on a Medical Bill

A provider suing over a medical bill must show that it provided the services, that you are responsible for paying (often through a financial responsibility form signed at admission), what was charged, what insurance paid or adjusted, and the balance left. If a buyer sues instead, it must also prove each transfer of the account to itself (Rule 508.2–508.3 in justice court) through admissible business records (Texas Rules of Evidence 803(6), 902(10)). Also check for unresolved insurance claims, any financial assistance application you made, and whether the bill belongs to you or to another family member.

Medical Collections and Your Credit Report

IC System says it offers credit reporting to qualifying clients. The three national credit bureaus have voluntarily stopped reporting paid medical collections (since July 1, 2022) and medical collections with an original balance under $500 (since April 2023), and they wait a year before reporting unpaid ones. A federal rule that would have removed most medical debt from credit reports was vacated by a federal court in Sherman, Texas on July 11, 2025, before it took effect (Cornerstone Credit Union League v. CFPB, No. 4:25-cv-16 (E.D. Tex.)). See our update on the bureaus' medical debt policies.

Old Medical Bills and Limitations

Texas generally allows four years to sue on a debt (Civil Practice and Remedies Code § 16.004). Against a provider suing on its own bill, limitations is a defense you must raise in your answer. Finance Code § 392.307, which bars suits on time-barred consumer debt, applies to debt buyers, so it matters only if a buyer is the plaintiff. Regulation F prohibits any debt collector, including a collection agency, from suing or threatening to sue on time-barred debt (12 C.F.R. § 1006.26(b)). The Fifth Circuit has held that "urgent" collection letters on a time-barred Texas medical debt, silent about its age, can violate the FDCPA (Manuel v. Merchants & Professional Bureau, Inc., 956 F.3d 822 (5th Cir. 2020)); that case involved a different collector and says nothing about IC System or your account.

IC System and Your Rights Under the FDCPA and Texas Debt Collection Act

IC System says it collects for original creditors, so it collects debts owed to another and is generally a "debt collector" under the Fair Debt Collection Practices Act when it collects consumer debts (15 U.S.C. § 1692a(6)). It must send validation information (§ 1692g) and follow Regulation F's limits on calls, texts and emails. It is also a bonded third-party debt collector under the Texas Debt Collection Act, which reaches original creditors too, so a hospital or provider collecting its own bill must follow Texas rules.

Common violation categories include:

• Harassment, such as repeated calls or abusive language (15 U.S.C. § 1692d; Tex. Fin. Code § 392.302).
• Threats of arrest or of action that cannot legally be taken (§ 1692e(4)–(5); § 392.301).
• False statements about the amount or legal status of the debt (§ 1692e; § 392.304).
• Unauthorized interest or fees (§ 1692f(1); § 392.303(a)(2)).
• Telling others about the debt, such as your employer or relatives (§§ 1692b, 1692c(b)).
• Contacting you directly after learning you have a lawyer (§ 1692c(a)(2)).

Our Texas FDCPA attorney page covers these rules in more depth.

If IC System or a provider collecting a bill has harassed, threatened or misled you, keep a log of calls and letters and request a free case evaluation. FDCPA claims generally must be filed within one year (§ 1692k(d)). Where the facts support them, we bring these claims as a separate federal lawsuit rather than a counterclaim.
