Texas Home Care Prior Authorization — STAR+PLUS & HHSC

Texas home care agencies operating under STAR+PLUS Medicaid face a prior authorization environment that is structurally different from fee-for-service states. Because Texas routes almost all Medicaid PAS (Personal Attendant Services) and CFC (Community First Choice) services through managed care organizations rather than direct HHSC billing, the prior authorization relationship runs between the agency and each individual MCO — not with the state.

That means an agency with 30 active clients across four STAR+PLUS MCOs is managing four separate authorization workflows simultaneously. Superior Health Plan has its own portal, its own documentation requirements, and its own re-authorization timeline. Molina Healthcare of Texas uses a different system. UnitedHealthcare Community Plan Texas and Aetna Better Health Texas each add their own process layer. A fifth MCO — Community First Health Plans, active primarily in the Houston Service Delivery Area — applies a sixth framework for agencies working in that market.

The cumulative administrative weight of this multi-MCO prior auth management is one of the main reasons back-office staffing ratios are higher in Texas than in single-payer states. A claim denied for "authorization not on file" at the time of service is one of the most preventable denial categories — and one of the most common for agencies that treat prior authorization as a case-by-case task rather than a managed function.

The Referral-to-Authorization Pathway

For STAR+PLUS members, prior authorization begins with the MCO's own service coordinator (sometimes called a case manager or care coordinator). The service coordinator completes a functional assessment — typically HHSC's standardized tool or the MCO's proprietary equivalent — to determine the member's eligible service hours and service types. The outcome of that assessment drives the prior authorization.

The service coordinator then issues a referral to the home care agency. This referral is not the authorization — it is the MCO's instruction to contact the member and begin the intake process. The authorization itself is issued separately, either automatically following the referral or after the agency submits additional documentation to the MCO's prior auth team.

Agencies that confuse the referral confirmation with the authorization create a billing problem before services start: services provided on a referral without a finalized authorization on file are non-covered.

Authorization Documentation Requirements

Before a STAR+PLUS PAS authorization can be fully processed and confirmed, the agency typically needs to have the following on file:

Physician Order (Plan of Care / CMS 485): A signed physician order authorizing home care services. The MCO specifies how recently the signature must be dated relative to the authorization start. Most STAR+PLUS MCOs require the physician order to be signed within 30 to 60 days of the date services begin — an expired or pre-dated order is a common auth documentation gap.

MCO Service Plan or Authorization Notice: The MCO issues an authorization document that specifies the authorized service type (PAS, CFC, or the applicable STAR+PLUS service category), authorized hours per day or week, and the authorization start and end dates. This document is the billing anchor — every claim submitted must reference an authorization period that covers the date of service.

Signed Service Agreement: A service agreement between the agency and the member confirming the services to be provided, the care schedule, and the member's rights and responsibilities. Most MCOs require this on file before finalizing the authorization.

HCSSA License Verification: Many MCOs confirm the agency's current HCSSA license status at the time of initial authorization and at re-authorization. A lapsed license terminates the authorization relationship automatically.

A smaller portion of Texas home care clients receive Medicaid PAS through HHSC directly — fee-for-service (FFS) — rather than through a STAR+PLUS MCO. This pathway applies primarily to members in rural areas without MCO coverage, members in the STAR+PLUS program during a transition gap, or members in specific waiver programs that HHSC administers directly.

For FFS prior authorization, the fiscal agent is TMHP (Texas Medicaid & Healthcare Partnership). HHSC service coordinators initiate the prior authorization through their own case management process, and the resulting authorization is reflected in TMHP's system. Agencies bill TMHP directly for FFS services using the prior auth number on the claim.

The FFS prior authorization process requires that the agency be enrolled with TMHP as a PAS provider — separate from MCO credentialing — and that the claim is submitted within TMHP's timely filing deadline (generally 95 days from the date of service for most PAS claim types, though agencies should verify this in the current TMHP provider manual).

Authorization Expiration Tracking

An authorization expiration date is a hard deadline. Unlike a physician order, which may have some flexibility in how lapsed orders are handled during active care, an authorization expiration creates an immediate billing barrier: dates of service after the expiration are non-covered until a new authorization is in place.

For agencies managing a census of 20 or more clients across multiple MCOs, tracking authorization expiration dates manually — in a spreadsheet or in the notes field of a scheduling system — creates predictable failure points. The most common pattern: an authorization expires on the 15th of the month, services continue because the scheduler was not alerted, and claims for dates 16 through 30 generate a batch of authorization-not-on-file denials that take 30 to 60 days to recover — if they are recoverable at all.

Effective prior authorization management requires:

1. A centralized authorization registry that lists each active client's current authorization number, authorized service type, authorized hours, authorization start date, authorization end date, and the MCO responsible.

2. A 30-day advance alert system that flags upcoming expirations so the re-authorization request is submitted before the current authorization lapses.

3. Confirmation that the new authorization is on file before continuing services past the expiration date — even if the re-authorization request was submitted on time. MCO processing timelines vary; if the re-authorization has not been confirmed, the service gap must be communicated to the client and caregiver.

Re-Authorization Triggers

Beyond the routine expiration timeline, re-authorization is required when any of the following occur:

• Service plan change: The member's functional assessment changes and the MCO updates the authorized service hours or service type
• MCO transfer: The member switches from one STAR+PLUS MCO to another (during open enrollment or following a Medicaid eligibility change). The new MCO issues its own authorization; the previous MCO's authorization is not transferable.
• Caregiver type change: If the member's authorized service switches between PAS, CFC, or another service category that requires a different caregiver certification
• Agency transition: If the member transfers from another home care agency, the receiving agency must obtain a new authorization — it does not assume the prior agency's authorization

The prior authorization errors that generate the most claim denials are almost always preventable:

Authorization not on file at time of service: The authorization was not confirmed before services began, or the authorization expired and services continued. Prevention: never start or continue services without a confirmed authorization in the system. Build a pre-service authorization confirmation step into the intake and scheduling workflow.

Wrong service type authorized: The claim billed PAS but the authorization was for CFC, or vice versa. Prevention: confirm that the authorized service type on the MCO authorization document matches the service type being billed before the first visit.

Physician order expired: The Plan of Care supporting the authorization was not renewed within the MCO's required timeframe. Prevention: track physician order renewal dates alongside authorization expiration dates. Both need a 30-day advance alert.

Member MCO change not updated: The client changed MCOs during open enrollment or following an eligibility review, and the agency continued billing the old MCO without obtaining authorization from the new one. Prevention: verify MCO assignment at the start of each billing month, particularly in January and July (common HHSC open enrollment and renewal periods).

Authorization submitted to the wrong MCO portal: The agency submitted the re-authorization request through the wrong MCO's portal — often because the client's MCO changed and the system was not updated. Prevention: confirm MCO assignment at every re-authorization cycle.

Prior authorization management at the census level where it matters most — 20 to 60 active clients across multiple MCOs — is a full-time tracking and coordination task, not an occasional administrative duty. The agencies that manage prior authorization most effectively at scale are those that assign it as a dedicated function.

A trained intake coordinator VA handling prior authorization tracks authorization expirations across the census, submits re-authorization requests through each MCO's portal before the current authorization lapses, confirms new authorization numbers before services continue past an expiration date, documents all authorization communications in the scheduling system, and flags any member MCO transitions that require a new authorization from the incoming plan.

This function pairs naturally with intake coordinator duties — the same VA who handles new member intake documentation (referral confirmation, service agreement, physician order collection) is well-positioned to own the ongoing authorization tracking lifecycle for that member's file. The intake-through-re-authorization workflow is one continuous documentation thread, and assigning it to a single accountable role prevents the handoff gaps where authorizations most commonly lapse.

For Texas agencies evaluating whether prior authorization tracking justifies a dedicated VA role, the billing denial recovery cost of a single authorization lapse — typically one to three hours of admin time per denied claim, often with lower recovery rates than timely filing or EVV denials — usually makes the math straightforward. The home care virtual assistants Atlas Care deploys to Texas agencies are trained on STAR+PLUS authorization workflows, MCO portal navigation, and the pre-expiration re-authorization submission process.

For agencies just getting started with STAR+PLUS prior authorization management, the setup steps are:

1. Complete MCO credentialing before accepting referrals. An agency cannot receive valid authorizations from an MCO it is not yet credentialed with.

2. Obtain MCO provider portal credentials immediately upon credentialing completion. Each MCO has its own portal for checking authorization status, submitting re-authorization requests, and pulling authorization documentation.

3. Build the authorization registry before the first client is onboarded. A simple spreadsheet works at small census; a purpose-built field in your scheduling system (HHAeXchange, Sandata, AxisCare) is more maintainable at scale.

4. Establish the physician order renewal workflow alongside the authorization tracking workflow. The two expiration timelines are linked but not identical.

5. Assign a single owner to prior authorization tracking — not a shared responsibility between the scheduler and the owner. Shared responsibility for high-stakes tracking tasks creates predictable coverage gaps.

Agencies using remote back-office staff for these functions — intake, credentialing, authorization tracking — typically find that the cost structure of a virtual assistant is substantially lower than a full-time in-office equivalent at the same census level, particularly when the VA comes pre-trained on the Texas STAR+PLUS operational environment.

Prior authorization in Texas home care is not a one-time intake task — it is an ongoing compliance and billing function that operates in parallel with every active client's care delivery. The agencies that treat it as a managed function, with clear ownership, a centralized tracking registry, and advance alert systems for expirations, consistently outperform those that manage it case-by-case.

The administrative infrastructure for prior authorization — the tracking system, the re-auth calendar, the physician order renewal workflow — is the same infrastructure that determines how quickly a Texas agency can recover denied claims and how cleanly it can pass an HHSC audit. Getting this function right early is one of the highest-leverage back-office investments a new Texas STAR+PLUS agency can make.
