Texas prompt-pay discussions almost always reference two statutes: Chapter 843 and Chapter 1301 of the Texas Insurance Code. They are not interchangeable, and citing the wrong one in a dispute letter signals to the payer that you have not done your homework. Chapter 1301 is the statute that governs preferred provider benefit plans, the PPOs your commercial patients most commonly carry. Knowing what it requires, how to confirm a plan falls under it, and when to invoke it in a dispute is foundational for any Texas practice that bills commercial insurance.
What Chapter 1301 covers
Chapter 1301 of the Texas Insurance Code regulates preferred provider organizations and the preferred provider benefit plans they issue. A preferred provider benefit plan is what most people call a PPO: a commercial health plan that contracts a network of providers at negotiated rates and offers enrollees the option to use out-of-network providers at higher cost sharing. When a Texas-regulated commercial insurer issues a PPO-type plan to an employer group or individual in Texas, Chapter 1301 sets the rules for how that insurer must handle claims.
The core obligation for providers: payers subject to Chapter 1301 must pay or formally contest a clean claim within the timeframes the statute specifies. Failure to do so triggers the interest provisions that make Texas prompt-pay law meaningful for practices willing to enforce it.
Chapter 843 versus Chapter 1301
The two chapters cover different plan structures. Mixing them up in a dispute is a common and costly mistake.
- Chapter 843 covers Health Maintenance Organizations. HMO plans typically require enrollees to designate a primary care physician, get referrals for specialist visits, and stay in-network for covered care.
- Chapter 1301 covers preferred provider benefit plans (PPOs). PPOs allow out-of-network use but at a higher patient cost-share, and they generally do not require referrals.
Before sending any prompt-pay dispute letter, pull the patient's Explanation of Benefits or check the insurer's provider portal to confirm the plan type. The insurance card often says "PPO" or "HMO" but is not always conclusive. A call to the payer's provider relations line to confirm the plan type and the governing Texas statute is worth the five minutes.
Clean claims and payment deadlines
Chapter 1301 requires payers to pay or formally contest a clean claim within set timeframes from the date they receive it. The general framework under the statute holds electronic claims to approximately a 30-day window; paper claims typically carry a longer deadline. These numbers are specified in the statute and subject to change, so verify current requirements before calculating a deadline in a live dispute.
"Clean claim" is the key phrase. A clean claim is one that contains all the information the payer needs to adjudicate it without requesting additional data. If a claim is missing a diagnosis code, has a mismatched NPI, or omits a required modifier, the payer can request additional information and suspend the payment clock. Getting the claim clean on the first submission is the most direct way to shorten your payment cycle and strengthen any later dispute.
Interest on overdue payments
When a state-regulated PPO payer misses the Chapter 1301 payment deadline on a clean claim, the statute provides for interest on the overdue amount. The rate is commonly cited at up to 18% per annum, accruing from the date payment was due. The exact conditions and mechanics are specified in the Texas Insurance Code; consult a Texas healthcare attorney or billing compliance professional for guidance specific to your situation before asserting interest amounts in a demand letter.
What matters operationally: payers do not volunteer this interest. You calculate the accrual, document it, and request it through the payer's contract dispute channel. The 18% interest guide covers the calculation method and how to structure the demand.
The self-funded plan exception
This is the biggest practical limitation of Chapter 1301. The statute only applies to state-regulated commercial plans. Many employer-sponsored health plans are self-funded: the employer bears the insurance risk directly and hires a commercial insurer only to administer the plan. Self-funded plans are governed by the federal Employee Retirement Income Security Act (ERISA), which generally preempts state insurance law. A self-funded plan is not subject to Chapter 1301, regardless of which insurer's name is on the card.
This matters because a significant share of commercially insured patients at any practice may be on self-funded plans. Filing a Chapter 1301 dispute against a self-funded plan produces no result and delays resolution. To verify plan type, review the Summary Plan Description, ask the employer's benefits department directly, or look for "self-funded" or "self-insured" in the Explanation of Benefits. The insurance card alone is not sufficient; a United Healthcare or Aetna card may be either fully insured or self-funded.
Texas Department of Insurance enforcement
TDI regulates payers subject to Chapter 1301. If a state-regulated commercial PPO payer repeatedly fails to meet payment deadlines, a TDI complaint places the payer under regulatory scrutiny and creates a documented record. TDI has authority to direct payment of outstanding amounts including statutory interest and can impose penalties on payers with patterns of violations. A single complaint can cover multiple claims from the same payer, making it efficient for practices with a documented pattern of late payment.
See the TDI penalties guide for how the complaint process works and the escalation sequence guide for the full dispute-to-complaint path. The Texas Prompt Pay Act overview covers both Chapter 843 and Chapter 1301 together for a complete picture.
Three questions before citing Chapter 1301
Every Chapter 1301 dispute starts with three confirmations:
- Is the plan a state-regulated commercial PPO, not a self-funded ERISA plan, a Medicaid managed-care plan, or a Medicare Advantage plan?
- Do you have the 277 acknowledgment or other documentation establishing when the payer received a clean claim?
- Has the applicable payment deadline actually passed from the receipt date (not from the date of service or submission)?
With those three facts confirmed, a written demand citing Texas Insurance Code Chapter 1301 by name, the specific claim number, the verified receipt date, the number of days overdue, and the calculated interest accrual carries meaningfully more weight than a generic request for faster payment. Specificity signals that you know your rights and will escalate.
