Plans from HHSC's managed care service areas map (revised August 2026) and the STAR+PLUS contract awards that took effect September 1, 2024; counties from HHSC's Nueces STAR comparison chart. HHSC's STAR+PLUS and STAR Kids county lists for Nueces leave out Goliad, so check the county your clients live in.

The license doesn't change on the coast

HHSC licenses every Texas substance use program as a chemical dependency treatment facility under Health and Safety Code chapter 464 and 26 TAC 564. Corpus Christi adds no treatment license of its own. As of October 2026 the fee under 26 TAC 564.408 is $1,200, plus $125 for each additional site. What the coast changes is the order of your preparation:

• Have the certificate of occupancy before you file. HHSC's inspector and later an accreditor will ask for it, and on the coast a build-out can stall on windstorm inspections. Don't start the license clock until the building is close to done; the full packet is in our CDTF license guide.
• Write the hurricane plan into your policies, not just a binder. 26 TAC 564.707 already requires written procedures for medical and psychiatric emergencies; on the coast, extend your policies to storm closures, client contact during an evacuation, and counseling by telehealth under 564.911's consent and identity rules. Rule-by-rule proof is in 26 TAC 564 in plain English.

The whole statewide sequence, from plan to first admission, is in how to start an IOP or PHP in Texas.

Permits and the certificate of occupancy

Inside city limits, the Development Services Department handles building permits and certificates of occupancy. The city's Information Bulletin 017 (January 23, 2024) explains the rule that matters most when you lease an existing space: under the adopted International Building Code, a building can't be used or occupied until the building official issues a certificate of occupancy. A new tenant who isn't building can sometimes keep the existing certificate or just update the name, but a change of use needs a new application, and that triggers building, fire, mechanical, electrical and plumbing inspections to check the occupant load and occupancy classification.

A former retail or office suite turned into group rooms is often a change of use, because group rooms raise the occupant load. Ask DSD in writing before you sign:

1. Is an outpatient substance use treatment program allowed at this address under the zoning, without a special approval?
2. Is moving in a change of use, or does the existing certificate of occupancy cover our use and headcount?
3. Which permits and inspections will our build-out need, including windstorm certification for any exterior work?
4. What does the fire marshal check before we open, and how long are reviews running?

Addresses in Portland, Robstown, Kingsville or unincorporated Nueces and San Patricio counties answer to those jurisdictions instead. Lease with a contingency for the certificate of occupancy and the HHSC license. Every site step is on our Texas IOP opening checklist.

Windstorm, flood and hurricane planning

This is what makes the Coastal Bend different from an inland Texas city.

• Windstorm certification. TDI's windstorm inspection program covers the designated catastrophe area, which includes Nueces, San Patricio, Aransas, Kleberg, Kenedy, Refugio and Calhoun counties. Most new construction, roof replacements, major repairs and alterations there need inspection by a TDI-appointed engineer while the work is done, and a certificate of compliance (the WPI-8) (TDI: do you need a windstorm inspection?). Without it, the building may not qualify for wind and hail coverage from the Texas Windstorm Insurance Association. Ask the landlord for the building's certificates before you sign, and budget for certification on any exterior work in your build-out.
• Flood zones. Check the address on FEMA's Flood Map Service Center before you tour it seriously. A ground-floor group room in a flood zone can mean higher insurance, a longer closure after a storm, and harder questions from a landlord's lender.
• Hurricane season runs June 1 to November 30. Plan how you'll close, tell clients, keep counseling going by telehealth where the client's plan covers it, protect records, and reopen. Comply's emergency operations plan guide and hazard vulnerability analysis walk through both; a coastal program should rank hurricanes and flooding at the top.
• Records and billing in a storm. A cloud EHR keeps charts reachable when the building isn't. Ours, Cima EHR for IOP and PHP, runs in the browser, so staff can document from wherever they evacuated to.

Medicaid plans in the Nueces service area

After the HHSC license, enroll with TMHP, then credential with each plan. TMHP has said Medicaid SUD treatment may only be delivered in a licensed chemical dependency treatment facility (TMHP notice).

Program	Who it covers	Plans in the Nueces service area
STAR	Most children, pregnant women and some families	Driscoll, Superior, UnitedHealthcare
STAR+PLUS	Adults with disabilities and adults 65 and older	Superior, Wellpoint
CHIP	Children in families above Medicaid income	Driscoll, Superior, UnitedHealthcare

• Superior is the one plan in both adult programs. An adult program that wants STAR (pregnant women and some parents) and STAR+PLUS can start with Superior, then add Wellpoint for STAR+PLUS and UnitedHealthcare or Driscoll for STAR. See our Superior HealthPlan and Wellpoint Texas guides.
• UnitedHealthcare isn't in STAR+PLUS here. Its 2026 Texas provider manual lists Nueces for STAR and CHIP only, so don't count on it for adults with disabilities.
• Driscoll Health Plan is the local plan, tied to Driscoll Children's Hospital, and serves the Coastal Bend and the Rio Grande Valley. It matters most to adolescent programs.

The step-by-step is in our Texas Medicaid credentialing guide, and every area's line-up is in Texas Medicaid health plans by service area. Our credentialing service files and follows each application for you.

Naval air stations and TRICARE

Naval Air Station Corpus Christi and Naval Air Station Kingsville put military families and retirees in your market. Texas has been in TRICARE's West region since January 1, 2025, so programs join through TriWest Healthcare Alliance (TRICARE). TRICARE pays an IOP or PHP only under a participation agreement that requires accreditation (TRICARE Policy Manual). A new program can't be accredited until it has clients and charts, so plan the survey for your first year. See our TRICARE credentialing guide, accreditation for new programs and the Program Launch + Accreditation package.

The local landscape

Build referral relationships on quick assessments, honest level-of-care calls and good communication. Paying or giving anything of value for referrals is illegal under the Texas Patient Solicitation Act and federal EKRA (patient brokering laws, explained). We never arrange referrals.

• The local mental health authority. The Behavioral Health Center of Nueces County (legally Nueces County MHMR Community Center) is the authority for Nueces County only (HHSC's LMHA directory). Clients from San Patricio, Kleberg or the other service-area counties have their own authorities; look them up in the same directory. Agree on crisis hand-offs before you open.
• OSAR. HHSC funds Outreach, Screening, Assessment and Referral programs that link people to state-funded substance use treatment (HHSC OSAR page). Find the provider for your region there, and decide early whether you'll take state-funded clients at all.
• Hospitals. The CHRISTUS Spohn hospitals and the other Corpus Christi systems discharge patients who need a step down. Case managers want your levels of care, accepted plans and how fast you can assess.
• Courts and probation. If a county runs a drug court or other specialty court under Government Code chapter 123, reports to it need the client's written consent under 42 CFR Part 2.
• Spanish-language services. Under 26 TAC 564.506 the client bill of rights, HHSC's complaint information and the grievance procedure are posted in English and a second language. In the Coastal Bend, bilingual counselors and Spanish intake packets do more for access than any ad.

Legal marketing, from directories to paid search, is in how to market a treatment center.

Questions

Which Medicaid plans serve Corpus Christi?

HHSC's August 2026 map lists Driscoll, Superior and UnitedHealthcare for STAR, and Superior and Wellpoint for STAR+PLUS, in the Nueces service area. Superior is the only plan in both.

Do I need a windstorm inspection for an outpatient program in Corpus Christi?

For new construction, roof work, major repairs and many alterations in Nueces County, yes: TDI's program requires inspection by an appointed engineer and a certificate of compliance. Interior-only work may not, so ask DSD and the engineer what your scope triggers.

Do I need a new certificate of occupancy to open in an existing building?

If your use is different from the last tenant's, usually yes. The city's Information Bulletin 017 says a change of use needs a new application and building, fire, mechanical, electrical and plumbing inspections.

Who is the local mental health authority in Corpus Christi?

The Behavioral Health Center of Nueces County, legally Nueces County MHMR Community Center. It serves Nueces County; the surrounding counties have their own authorities, listed in HHSC's directory.

How long does it take to open an IOP in Corpus Christi?

Plan on nine to twelve months to a full caseload of insured clients. Windstorm inspections can add time to a build-out, and TRICARE comes only after accreditation.

Other Texas cities: the Rio Grande Valley, Beaumont–Port Arthur, Houston, San Antonio, and every city on opening a program in Texas, by city.

Cima Consulting isn't a law or accounting firm. HHSC, the city, TDI, TRICARE and each health plan make their own decisions; we don't guarantee approvals, rates or dates.
