Driscoll Health Plan credentialing for behavioral health providers and IOP/PHP programs

The short answer: be enrolled in Texas Medicaid (TMHP) with an active NPI, update your CAQH or Availity credentialing profile, then fill out Driscoll Health Plan's Request for Contract form (PROV-PR-033), one for each practice or facility location, and email it to DHPContracting@Dchstx.org. Driscoll then tells the Texas Medicaid credentialing verification organization to start verifying your file, and its Credentialing and Peer Review committee decides. A clinician joining a group that already contracts with Driscoll uses a separate form (PROV-PR-034) and can ask for expedited credentialing (PROV-PR-032). Driscoll serves STAR, STAR Kids and CHIP in the Coastal Bend (Nueces) and STAR and STAR Kids in the Rio Grande Valley (Hidalgo).

Below is each step, sourced to Driscoll's own forms, quick reference tools and notices, from a team that runs a licensed Texas PHP, IOP and outpatient program.

Updated October 24, 2026. Driscoll, HHSC and TAHP sources checked October 24, 2026. Driscoll posts changes as dated notices and monthly quick reference tools; check its provider site for the newest before you file.

Driscoll at a glance

QuestionAnswer
Who it isDriscoll Health Plan (DHP), a non-profit, community-based plan that is part of the Driscoll Health System in Corpus Christi. It says it serves 24 counties in the Nueces and Rio Grande Valley areas.
ProgramsNueces: CHIP (since 2000), STAR (since 2006), STAR Kids (since 2016). Hidalgo: STAR (since 2012) and STAR Kids (since 2016).
Before anythingTexas Medicaid enrollment and an active NPI, which Driscoll requires before it accepts the request; a current CAQH or Availity profile.
How to applyRequest for Contract (PROV-PR-033), emailed to DHPContracting@Dchstx.org, one per location.
VerificationThe Texas Medicaid CVO (Driscoll's documents name both Verisys and Aperture), then Driscoll's Credentialing and Peer Review committee.
Adult PHP and IOPOffered to STAR and STAR Kids members as in-lieu-of services; approval needed for members 21 and older.

Where Driscoll serves

Driscoll's 2023 behavioral health workshop gives its program history by area (Driscoll behavioral health workshop), and HHSC's managed care service areas map (2026 revisions) shows who else is there:

Service areaCountiesDriscoll's programsOther plans there
Nueces (Corpus Christi, Coastal Bend)Aransas, Bee, Brooks, Calhoun, Goliad, Jim Wells, Karnes, Kenedy, Kleberg, Live Oak, Nueces, Refugio, San Patricio, VictoriaSTAR, STAR Kids, CHIPSTAR and CHIP: Superior, UnitedHealthcare. STAR+PLUS: Superior, Wellpoint
Hidalgo (Rio Grande Valley, Laredo)Cameron, Duval, Hidalgo, Jim Hogg, Maverick, McMullen, Starr, Webb, Willacy, ZapataSTAR, STAR KidsSTAR: Molina, Superior, UnitedHealthcare. CHIP: Molina, Superior. STAR+PLUS: Molina, Superior, UnitedHealthcare

What that means for your program. Driscoll isn't a STAR+PLUS plan, so it doesn't cover adults with disabilities or adults 65 and older. Its members are mostly children and teens, children and young adults with disabilities (STAR Kids), and the pregnant women and parents in STAR.

  • An adolescent IOP in Corpus Christi, McAllen, Brownsville or Laredo: Driscoll belongs on the first list, because it carries STAR and STAR Kids in both areas and CHIP in Nueces. See how to run an adolescent IOP in Texas.
  • An adult SUD IOP: start with Superior (in STAR and STAR+PLUS in both areas), then add Driscoll for its adult STAR members, for whom it approves PHP and IOP as in-lieu-of services. Our city guides for Corpus Christi, the Rio Grande Valley and Laredo list the full local line-ups.

Contract status: HHSC's 2024 tentative STAR and CHIP awards left Driscoll out (Texas Tribune), and a Travis County judge then paused that procurement (Fierce Healthcare). We found no final new contracts, and Driscoll is on HHSC's 2026 map. Check the current map before you build a program around one plan.

Before you apply

  • TMHP enrollment and an active NPI. Driscoll's Request for Contract says providers must be enrolled in Texas Medicaid and have an active NPI before they submit it. Driscoll also asks providers to keep enrollment and demographic data current with TMHP, because the plans reconcile their records against it. Our Texas Medicaid enrollment guide walks through PEMS.
  • LPCs and LMFTs: Medicare, or the pediatric exemption. Since March 1, 2024, Texas Medicaid has required LPCs and LMFTs to enroll in Medicare or claim a pediatric practice exemption in PEMS (BCBSTX Medicaid notice, 2024). For a children's plan, the exemption is often the route; our Medicare guide for LPCs and LMFTs covers both.
  • A current credentialing profile on CAQH ProView or Availity, with every document unexpired. The CVO works from it. Our CAQH ProView guide covers each section.
  • For a program: the HHSC license for each site, covering the ages you treat, the organization NPI and TPI, liability certificates and an ownership chart. See how to get a Texas CDTF license.

PEMS credentialing. In April 2025 Driscoll told providers that PEMS would add a credentialing tab so providers could start managed care credentialing there, while the plans and the CVO keep their roles (Driscoll PEMS notice). HHSC postponed that update in May 2025, and a December 2025 Texas plan notice described a soft launch for facility credentialing only (Community Health Choice notice). Ask Driscoll which route it wants when you file.

The three forms

FormUse it whenWhat happens next
PROV-PR-033 Request for ContractYou, your group or your facility want a new contract with DriscollDriscoll notifies the CVO, which starts credentialing from your CAQH or Availity application
PROV-PR-034 Request to Credential New Provider to Existing GroupYour group already contracts with Driscoll and is adding a clinicianThe new clinician is credentialed under the group's contract
PROV-PR-032 Expedited Credentialing Request (with its addendum)The new clinician qualifies to see members provisionally while credentialing finishesProvisional status, until the Credentialing and Peer Review committee approves the clinician

All three are on Driscoll's provider site (Request for Contract, new provider to existing group, expedited request). The Request for Contract we checked is dated April 2023, so download the current one before you fill it in.

Step by step

  1. Confirm TMHP enrollment for each clinician and the facility, and that your PEMS, NPPES and CAQH addresses match.
  2. Update CAQH or Availity. Driscoll's form asks you to make sure all information is updated and every required document is current before you send it.
  3. Complete PROV-PR-033 for each location. Driscoll wants one form per practice or facility location. List your behavioral health specialty, the programs you want (STAR, STAR Kids, CHIP) and the ages you serve.
  4. Email it to DHPContracting@Dchstx.org and keep the sent message as your start date.
  5. Answer the CVO. Driscoll's form names Aperture, which older Texas plan documents name as the CVO, while its provider resources page names Verisys, the CVO the Texas Medicaid plans use now (TAHP's Credentialing 101). Either way, the shared CVO's verification counts for every Texas Medicaid plan, and the email asking for a missing item is the one to answer the same day.
  6. Sign the contract and confirm the effective date and programs in writing before you schedule Driscoll members.

For questions, use the Provider Relations contacts on Driscoll's current provider page; numbers differ between its older documents. Driscoll doesn't publish a credentialing timeline; on our Texas roadmaps we budget about 90 days for a Medicaid plan after TMHP and CAQH are done.

Expedited credentialing

Texas law requires every Medicaid plan to offer expedited credentialing to a clinician who joins an established group that already contracts with the plan, is enrolled in Texas Medicaid, agrees to the group contract's terms and sends what the plan requires on time (Texas Government Code §540.0656; 1 TAC §353.423). Superior's guide to the same law lists LCSWs, LPCs, LMFTs and psychologists among the eligible behavioral health types.

Driscoll's addendum to PROV-PR-032 has the clinician attest to a Texas license in good standing with no disciplinary history and an active Texas Provider Identifier, and to hold members harmless. Its wording names the Texas Medical Board, so a counselor or social worker should ask Driscoll for its Expedited Credentialing Criteria and how to complete the attestation for their own board. The addendum also says provisional status doesn't make the clinician a participating provider until the Credentialing and Peer Review committee approves them (Driscoll expedited addendum). Building a group? Our Group Practice Launch carries every clinician's plans on one roadmap.

For IOP and PHP programs

A program contracts as a facility on the same Request for Contract, one form per site. Ask Driscoll which facility credentialing application it wants; many Texas Medicaid plans take the Texas Association of Health Plans' standardized Texas Facility/Ancillary/Long-term Care Credentialing Application, which must not be reworded or reformatted.

What Driscoll pays for, by program. Driscoll's quick reference tool (September 2026) lists, for CHIP:

ServiceCodeCHIP, per Driscoll's tool
Partial hospitalizationH0035, S0201Covered benefit
Substance use IOPH0015Covered benefit
Mental health IOPS9480Not a CHIP benefit, but Driscoll provides it through participating in-network providers

For STAR and STAR Kids members 21 and older, Driscoll offers inpatient psychiatric care, partial hospitalization and intensive outpatient services as in-lieu-of services, with approval required (Driscoll's adult mental health and substance use page). Ask Driscoll how it authorizes PHP and IOP for members 20 and younger (see authorizations). Our Texas Medicaid IOP and PHP guide explains in-lieu-of services, and our guide to insurance contracts for treatment centers lists what to check before you sign: the codes, the per diem, which programs and ages, and whether your clinicians also need individual credentialing.

Authorizations by age and program

  • Adults (21 and older) in STAR and STAR Kids: Driscoll's November 2024 notice says prior authorization will always be required for PHP and IOP, in network and out of network (Driscoll authorization update, November 2024). It reversed an earlier 2024 notice, so read the newest one.
  • Members 20 and younger: a Driscoll medical necessity guideline said Driscoll wouldn't require authorization for PHP and IOP at these ages. Check the DHP authorization requirement lookup for each code before the first admission; the newest quick reference tools don't restate the age rule.
  • Timing: Driscoll's quick reference tools require admission notification and the authorization request within one business day of admission unless noted otherwise, and Driscoll won't accept an authorization request after the claim is submitted.
  • Where: the DHP provider portal.

Put the authorization number, dates and units in your EHR before day one, and request the concurrent review before the last approved day; our utilization review guide lays out the log. Cima EHR for IOP and PHP programs tracks authorized units against attendance so a lapsed authorization shows before the claim denies.

Claims: payer ID and 95 days

  • Timely filing: claims within 95 days of the date of service, per Driscoll's 2026 quick reference tools (Driscoll STAR, CHIP and STAR Kids QRT, September 2026). Our timely filing guide has the Texas rules.
  • Electronic claims: through Change Healthcare (Optum), payer ID 74284, on the same tools.
  • Eligibility every month: Medicaid members can change plans; check on admission and on the first of each month. Our sister site's VOB checklist lists the questions.

Why Driscoll files stall

  • The form sent before TMHP enrollment or with an inactive NPI; Driscoll requires both first.
  • One form for several sites; Driscoll wants one per location.
  • Expired documents in CAQH or Availity when the CVO pulls the file.
  • An LPC or LMFT without Medicare or the pediatric exemption in PEMS.
  • A facility license that doesn't cover the ages on the request.
  • An adult PHP or IOP admission without authorization, or a request sent after the claim.
  • Seeing members on expedited status before Driscoll confirms it in writing.

How we work a Driscoll file

Our credentialing service checks Driscoll's programs in your counties, enrolls you with TMHP, fills the right Driscoll form for each site, answers the CVO, follows up every two weeks, reviews the contract and confirms the effective date in writing before the first claim. On our Texas roadmaps, TMHP is budgeted at about 45 days and each Medicaid plan at about 90 days after TMHP and CAQH.

  • Texas Medicaid enrollment with your first managed care plan (Driscoll or another): $500 per clinician.
  • Driscoll as an additional plan for a clinician: $275 per plan.
  • A program's facility contract with Driscoll: $950 per plan.

Questions

How do I become a Driscoll Health Plan provider?

Enroll in Texas Medicaid and have an active NPI, update CAQH or Availity, then email the Request for Contract (PROV-PR-033) to [email protected], one form per location. Driscoll asks the CVO to verify your file, its committee decides, and you're in network from the effective date on your contract.

How do I add a new clinician to my group's Driscoll contract?

Use PROV-PR-034, the request to credential a new provider to an existing group. If the clinician qualifies, add the Expedited Credentialing Request (PROV-PR-032) and its addendum so they can see members provisionally once Driscoll confirms it.

Which counties does Driscoll Health Plan serve?

The Nueces service area (Corpus Christi and the Coastal Bend, 14 counties) and the Hidalgo service area (the Rio Grande Valley and Laredo, 10 counties): 24 in all, as Driscoll says. Check HHSC's map for each program by county.

Does Driscoll cover IOP and PHP for adults?

For STAR and STAR Kids members 21 and older, Driscoll offers PHP and IOP as in-lieu-of services, and its November 2024 notice requires prior authorization for them. It isn't a STAR+PLUS plan, so adults with disabilities and adults 65 and older are with other plans.

What is Driscoll's timely filing limit and payer ID?

95 days from the date of service, and payer ID 74284 through Change Healthcare, per its 2026 quick reference tools. Check your contract.

Does Driscoll Health Plan use CAQH?

Yes, CAQH or Availity. Driscoll's form says the CVO starts credentialing from your completed application on either one, so keep the profile current before you send the request.
