San Antonio Home Care Agency Operations: STAR+PLUS, MCOs, and the Bexar County Market

San Antonio is Texas's second-largest city and one of its highest-density Medicaid home care markets. Bexar County's combination of military retirees, a large Spanish-speaking senior population, and steady Medicaid enrollment growth creates consistent home care demand — and a complex compliance environment that stresses agencies built without dedicated back-office capacity. Home care agencies here navigate three STAR+PLUS MCOs, an eight-county service footprint, Sandata EVV mandates, and HHSC annual survey cycles, all in a labor market shaped by military employment, healthcare systems, and a bilingual workforce.

This guide covers the operational realities specific to San Antonio home care: the HHSC Bexar Service Area geography, the three active STAR+PLUS MCOs, EVV compliance requirements, HCSSA licensing, and the Bexar County caregiver market.

HHSC organizes Texas Medicaid home care into regional service areas. San Antonio agencies are assigned to the HHSC Medicaid Bexar Service Area, which covers:

• Bexar County — San Antonio, the urban core and the highest-density Medicaid population in the region
• Atascosa County — Pleasanton, Poteet, Jourdanton
• Bandera County — Bandera (Hill Country western edge)
• Comal County — New Braunfels, Schertz (northern suburban growth corridor)
• Guadalupe County — Seguin, Schertz, Cibolo (fast-growing suburban ring)
• Kendall County — Boerne (affluent Hill Country suburb)
• Medina County — Hondo, Castroville
• Wilson County — Floresville, La Vernia

A client's county of residence determines their service area assignment and the MCO choice set available to them. Agencies serving the fast-growing suburban ring north of San Antonio — New Braunfels, Schertz, Cibolo, Boerne — are within the Bexar Service Area and the same three-MCO choice set, even though those suburbs sit in Comal, Guadalupe, and Kendall counties respectively.

The southern and western counties — Atascosa, Medina, and Wilson — introduce a rural service dimension that creates EVV compliance complexity: caregivers in Pleasanton, Hondo, or Floresville face GPS accuracy issues and connectivity gaps that generate higher exception rates than urban Bexar County routes. Agencies covering the full eight-county footprint need reliable daily exception resolution to avoid claims delays.

Under the STAR+PLUS managed-care contracts effective September 1, 2024, three MCOs serve the HHSC Bexar Service Area. Every STAR+PLUS home care agency in San Antonio must credential with each plan independently:

Community First Health Plans

Community First Health Plans is the locally based San Antonio MCO — founded in the city, headquartered in San Antonio, and the only locally governed STAR+PLUS plan in the state. Its credentialing and provider portal are distinct from national plans, and its authorization processes reflect the local operational culture of the Bexar market. Many San Antonio agencies find Community First to be a meaningful portion of their STAR+PLUS enrollment volume. Agencies new to the Bexar Service Area should treat Community First credentialing as a separate workflow entirely — not an extension of any national MCO process.

Molina Healthcare of Texas

Molina holds contracts across multiple Texas STAR+PLUS service areas. Prior authorizations are submitted through Molina's provider portal, and Molina maintains separate EVV reconciliation requirements from Community First. Molina's credentialing cycle and re-credentialing documentation standards apply uniformly across its Texas service area footprint.

UnitedHealthcare Community Plan

UHC is active across the full Bexar Service Area. Authorizations and claims are managed through UHC Provider Express. Like Molina, UHC operates across multiple Texas service areas, and its credentialing requirements — including re-credentialing timelines and documentation standards — apply consistently. UHC's prior authorization processes and denial patterns differ from both Community First and Molina, requiring dedicated tracking by plan.

San Antonio agencies manage three sets of credentialing files, three authorization workflows, and three billing portals simultaneously. This three-MCO complexity is greater than Austin (two MCOs) and comparable to Houston and Dallas (three and three MCOs respectively). The locally based Community First plan adds a portal and process not encountered elsewhere in Texas — agencies expanding from other markets into San Antonio often underestimate the Community First onboarding timeline.

San Antonio and Austin are neighboring markets on the I-35 corridor and are sometimes treated interchangeably by agencies with regional ambitions — but HHSC separates them into distinct service areas with different MCO sets.

Community First and Molina do not operate in the Travis Service Area. Superior Health Plan does not operate in the Bexar Service Area. Agencies credentialed in Austin for Superior and UHC cannot bill those same contracts for Bexar County clients — credentialing must be completed separately for the Bexar Service Area's three plans. For more detail on the Austin operational context, see the Austin Home Care Agency Operations Guide.

Every agency providing home care in Bexar County must hold a current Texas HCSSA license issued by HHSC. HCSSA license types relevant to San Antonio agencies include:

• Personal Assistance Services (PAS) — non-skilled personal attendant care, the most common license type for STAR+PLUS home care agencies
• Licensed Home Health (LHH) — skilled nursing and therapy services
• Home Care Services (HCS) — IDD waiver and related services

HHSC conducts an initial licensing survey before a new agency can begin serving Medicaid clients, followed by annual compliance inspections. Survey readiness requires current policy and procedure manuals, caregiver credential files (training records, background checks, TB screenings), client documentation, and supervisory visit logs. Gaps in any category are citable deficiencies.

For the full HCSSA license application process — from license type selection through TULIP portal submission and HHSC survey preparation — see the Texas HCSSA License Application Checklist.

Texas Medicaid requires Electronic Visit Verification for personal care and home health services. The state-mandated EVV system for most STAR+PLUS MCOs in Texas is Sandata. Agencies that use HHAeXchange as their home care platform can alternatively run EVV natively through HHAeXchange.

Common exception types that San Antonio agencies resolve daily:

• Clock-in/out gaps — missing or out-of-window visit recordings
• GPS location mismatches — caregiver location at clock-in doesn't match client address
• Missed-visit documentation — required reasons for visits not completed
• Service mismatch — documented service type doesn't match authorized service

The rural counties of the Bexar Service Area — Medina, Atascosa, and Wilson — present elevated EVV error rates. Caregivers working in Hondo, Pleasanton, or Floresville often encounter GPS signal degradation and cellular connectivity gaps that produce false location mismatches. Unresolved exceptions delay claims across all three MCO payers. For a detailed walkthrough of exception categories and resolution workflows, see EVV Compliance for Home Care Agencies.

San Antonio is one of the most bilingual metros in the United States. Bexar County's Spanish-speaking population — both clients and caregivers — is among the largest in Texas, and this shapes home care operations in ways that agencies from other markets often underestimate.

Bilingual intake matters. A meaningful percentage of Bexar County STAR+PLUS clients conduct intake calls, ask scheduling questions, and communicate care preferences primarily in Spanish. Agencies with English-only intake teams lose clients at the first phone interaction or generate miscommunications that lead to missed visits and complaints.

Bilingual recruiting is a competitive advantage. The caregiver talent pool in San Antonio includes a large Spanish-speaking workforce. Agencies that post job listings, conduct screening calls, and run onboarding in both English and Spanish consistently outperform agencies that do not — both in application volume and in caregiver retention, since caregivers who understand their employer's processes from day one have lower early-attrition rates.

Spanish-language prior authorization calls. MCO prior authorization teams — particularly at Community First and Molina — interact regularly with Spanish-speaking agency staff and clients. Bilingual back-office staff reduces hold times, miscommunication-driven denials, and resubmission cycles.

Atlas Care includes bilingual Assistants trained on Texas Medicaid workflows for San Antonio agencies that need Spanish-language coverage across intake, caregiver coordination, and MCO communications.

San Antonio's home care agencies compete for administrative and clinical support talent in a market defined by military employment, large healthcare systems, and a growing suburban economy.

Military community. Joint Base San Antonio (JBSA) — encompassing Fort Sam Houston, Lackland Air Force Base, and Randolph Air Force Base — is the largest military installation in the United States by land area and one of the largest employers in Bexar County. The military and defense ecosystem drives employment across a wide range of administrative and support roles, pulling talent from the same pool that home care agencies recruit from. Military spouses and veterans represent a significant portion of the San Antonio administrative workforce — agencies that actively recruit from this community often find highly organized, process-oriented candidates. The flip side: JBSA rotations create periodic churn when military families PCS to other bases.

South Texas Medical Center. The South Texas Medical Center — a 900-acre complex in northwest San Antonio — is one of the largest medical complexes in the United States. It houses University Health, Baptist Health System, Methodist Healthcare, UT Health San Antonio, the Audie Murphy VA Medical Center, and numerous specialty practices. Combined, these employers compete directly with home care agencies for scheduling coordinators, billing staff, medical records specialists, and administrative support talent. Healthcare system wages in San Antonio consistently exceed what a home care agency can offer for equivalent roles.

Growing suburban ring creates geographic spread. Comal and Guadalupe counties north of San Antonio — New Braunfels, Schertz, Cibolo — are among the fastest-growing counties in the United States. As the client population spreads across this wider geography, caregiver drive times increase and the scheduling challenge becomes more complex. Agencies that once served a compact Bexar County geography now manage routes extending 30–40 miles from the urban core.

Veteran and military retiree client population. JBSA's presence drives a significant veteran and military retiree population in Bexar County. The Audie Murphy VA Medical Center serves this population medically, but many veterans and military retirees also qualify for STAR+PLUS home care through Medicaid. Agencies that understand VA benefit coordination alongside Medicaid eligibility serve a client profile that some competitors miss.

San Antonio STAR+PLUS agencies carry the following administrative functions simultaneously:

• Scheduling and caregiver-to-client matching across an eight-county footprint, including rural counties with limited caregiver availability
• EVV exception resolution (daily) in Sandata and/or HHAeXchange
• MCO prior authorization requests and follow-up across three plans (Community First, Molina, UHC)
• Medicaid claims submission and denial management, per-plan
• HCSSA credentialing and credential expiration tracking
• Caregiver recruiting, screening, and onboarding (bilingual for Bexar County agencies)
• HHSC survey documentation and policy management
• Spanish-language intake and client communication

In a mid-sized San Antonio agency (20–60 clients), these functions require multiple full-time people to execute reliably. Three-MCO administrative overhead — versus two in Austin — is a material driver of back-office labor costs. Community First's local portal and credentialing process adds a workflow layer with no parallel at other Texas STAR+PLUS MCOs.

Atlas Care virtual assistants are trained on the tools and workflows San Antonio agencies run — Sandata, HHAeXchange, AxisCare, WellSky — including bilingual capability for Spanish-language intake and caregiver coordination. See the full Texas STAR+PLUS Medicaid payer guide for detailed MCO credentialing requirements, and the STAR+PLUS MCO provider enrollment guide for step-by-step enrollment instructions.
