Texas Provider Credentialing and Enrollment: TSCA, TMHP and Payer Rules

Credentialing in Texas is not one process. A new physician in a Dallas group may need the state’s standardized application for commercial plans, a TMHP Medicaid enrollment, a separate contract with each Medicaid managed-care plan, a Medicare enrollment, and a current CAQH profile. Each track has its own rules and its own clock. Every rule below links to the statute or agency page behind it.

The Texas Standardized Credentialing Application

The Texas Department of Insurance (TDI) publishes the Texas Standardized Credentialing Application, often shortened to TSCA. TDI states that form LHL234 is promulgated under Texas Insurance Code section 1452.052, which directs the insurance commissioner to prescribe a standardized form for verifying the credentials of a physician, advanced practice nurse, or physician assistant, and to require hospitals, HMOs and PPO issuers to use it.

What TDI’s page says, in plain terms:

• Who must use it: hospitals, HMOs and PPOs are required to use the form when credentialing physicians.
• Who may use it: hospitals and health plans may also use it to credential other health care professionals.
• Where it goes: the application is sent directly to the health benefit plan or workers’ compensation network you want to join. There is no central state clearinghouse.
• Where it came from: TDI notes that the form is based on one developed by CAQH (the Coalition for Affordable Quality Healthcare, which now operates as DataSpring).

TDI’s advice is to contact each company you want to contract with and ask about its credentialing process: whether it wants the TSCA itself, a CAQH profile, its own online application, or a combination.

Expedited credentialing under Texas Insurance Code chapter 1452, subchapter C

The gap between a physician’s start date and network approval is where revenue is lost. Chapter 1452, subchapter C lets some physicians be paid during that gap. Here is what sections 1452.101 through 1452.108 say.

Who it covers (sections 1452.101 and 1452.102)

The subchapter applies only to a physician who joins an established medical group that already has a contract in force with a managed care plan. “Managed care plan” includes plans issued by HMOs, PPO issuers and other issuers such as insurance companies. “Medical group” is defined in the statute and includes a legal entity owned by two or more physicians and a professional association of licensed physicians, among other forms.

What the physician must do (section 1452.103)

• Hold a Texas license and be in good standing with the Texas Medical Board.
• Submit all documentation and other information the plan requires to begin its credentialing process.
• Agree to follow the terms of the participating provider contract already in force with the group.

What the plan must do (section 1452.104)

Once the physician submits that information, the plan must treat the physician, for payment purposes only, as if they were a participating provider. That includes letting the physician collect in-network copayments and paying the physician’s claims.

The limits (sections 1452.105 through 1452.108)

• The plan may leave the physician out of its directory until the application is approved.
• If the physician ultimately fails credentialing, the plan may recover the difference between in-network and out-of-network payments from the physician or the group. The physician or group may keep copayments already collected.
• The patient is held harmless for that difference and may not be billed for it.

Subchapters D and E give similar treatment to podiatrists and therapeutic optometrists joining established practices. The protection does not reach a solo physician opening a new practice or a group with no existing contract with the plan.

Texas Medicaid: TMHP enrollment, then MCO contracting

Texas Medicaid provider enrollment is handled by the Texas Medicaid & Healthcare Partnership (TMHP) through its online Provider Enrollment and Management System (PEMS). TMHP states that enrolling in Texas Medicaid is a prerequisite for enrolling in other state health care programs.

Texas Medicaid also operates through managed care, and joining a managed care plan is a second, separate step. The Texas Medicaid Provider Procedures Manual lists the managed care programs as STAR, STAR+PLUS, STAR Kids and STAR Health, plus Children’s Medicaid Dental Services. The manual is direct about the order of operations:

• Providers must be enrolled in Texas Medicaid before a managed care organization (MCO) or dental maintenance organization can enroll them.
• Each MCO has its own guidelines for contracting.
• Medicaid MCOs must use the credentialing verification organization contracted by the Texas Association of Health Plans as part of credentialing and recredentialing.
• Texas Medicaid enrollment does not guarantee that any MCO will contract with or credential a provider, and TMHP cannot see individual MCO requirements.

A TMHP approval is the starting line. Plan a separate application and contract with each MCO whose members you expect to see.

Revalidation

Federal rules require the state Medicaid agency to revalidate every provider’s enrollment at least every five years (42 CFR 455.414). Your due date is shown in PEMS. TMHP’s June 2026 revalidation notice adds several practical points:

• Providers should start revalidation as early as 180 days before the due date.
• Beginning June 16, 2026, PEMS automatically extends the due date by 60 calendar days if the application was submitted before the due date and is still in review. Drafts do not count.
• Revalidation is not complete until the request reaches “Closed-Enrolled” status.
• Providers without a completed or in-review application by the day before the due date will be disenrolled from all Texas state health care programs, and claims and prior authorization requests will be denied. Disenrolled providers must submit a reenrollment application.

Texas SB 1266: notice before Medicaid disenrollment

Senate Bill 1266 of the 89th Legislature, “relating to Medicaid provider enrollment and credentialing processes,” took effect September 1, 2025. The enrolled text adds two sections to the Government Code.

Notice and a chance to fix (Government Code section 532.01512)

Before HHSC may disenroll a Medicaid provider for failing to complete the enrollment revalidation process, it must:

• send the provider written notice of the disenrollment determination, both electronically and by mail, at least 30 days before the disenrollment date; and
• allow the provider to address any deficiencies in the revalidation application before that date.

Keep the mailing address and email on your Medicaid enrollment record current. A notice sent to a closed office or a former manager’s inbox does not help you.

Portal support and complaints (Government Code section 532.01511)

HHSC must also provide a support team to help providers through enrollment and credentialing, evaluate that team annually and post the results by September 1 each year (the first report was due September 1, 2026), and offer an electronic form for complaints and feedback.

What changes in 2027: federal wait-time standards for Medicaid managed care

The 2024 federal Medicaid managed care rule (CMS-2439-F) adds appointment wait-time standards. According to CMS’s applicability date chart, the standards at 42 CFR 438.68(e) apply beginning with the first rating period that starts on or after July 9, 2027. The rule requires states to set and enforce routine appointment standards no longer than:

• 10 business days from the request for outpatient mental health and substance use disorder services, adult and pediatric;
• 15 business days for primary care, adult and pediatric; and
• 15 business days for obstetrics and gynecology,

in each case where the service is covered in the plan’s contract. States may set shorter limits and add other service types. The same chart lists state secret shopper surveys of wait times and directory accuracy for the first rating period on or after July 10, 2028.

When these standards reach a given Texas plan depends on the rating period in its state contract. Why it matters for credentialing: plans that must prove timely access need credentialed, accurately listed providers.

Medicare and commercial payers in Texas

Medicare

Medicare enrollment follows the same federal rules in Texas as elsewhere. Two matter before a start date:

• Retrospective billing: physicians, non-physician practitioners and their organizations may bill for services furnished up to 30 days before their Medicare effective date if circumstances prevented enrolling in advance, or up to 90 days in a presidentially declared disaster (42 CFR 424.521(a)).
• Revalidation: most providers and suppliers must resubmit and recertify their enrollment information every five years (42 CFR 424.515). CMS contacts the provider when it is time and expects the application within 60 calendar days of that notice.

CAQH (DataSpring)

Many commercial and managed care plans pull credentialing data from the CAQH Provider Data Portal. The CAQH Provider User Guide requires re-attestation every 120 days (180 days for Illinois providers). A profile that is not re-attested moves to “Expired” status the day after it is due.

Commercial plans

Commercial payers in Texas each set their own application steps, committee schedules and effective-date rules. Outside the chapter 1452 situation above, the effective date is whatever the payer’s approval says, so track each application separately.

Dallas–Fort Worth practices

AMS Solutions has been based in Dallas since 1992 and works in all 50 states. For DFW groups we run the Texas pieces above as one workflow: TSCA and CAQH, TMHP and each MCO, Medicare, and your commercial plans. Our medical credentialing services cover new enrollments, and credentialing maintenance keeps CAQH re-attestation and revalidation dates from slipping. Because our AAPC-certified coders also bill the claims, a gap in enrollment shows up before it becomes a denial. See medical billing in Dallas or medical billing services across Texas.
