Texas Medicaid Credentialing: TMHP Enrollment, the CVO, and Every MCO

Texas Medicaid credentialing runs on three separate tracks, and most delays come from treating them as one. You enroll with Texas Medicaid through TMHP. A single credentialing verification organization checks your credentials once for every Medicaid managed care plan. Then you contract with each plan separately. Finish all three and you’re in network; finish two and you can still be a provider no plan will pay.

This guide walks through each track, the deadlines Texas puts on health plans, the expedited credentialing rule that behavioral health groups often leave unused, and how to keep Texas enrollment active once you have it.

How Texas Medicaid Credentialing Works

Texas splits Medicaid participation into enrollment, credentialing, and contracting, and each one is handled by a different party. HHSC states plainly that providers serving managed care members must complete a separate contract and credentialing application with each MCO in addition to enrolling through PEMS, the state’s Provider Enrollment and Management System.

Credentialing itself is centralized. The Texas Association of Health Plans runs a consolidated process, and every Medicaid and CHIP MCO uses the same credentialing verification organization, Verisys, to verify a provider’s credentials. That’s the part most out-of-state groups get wrong in both directions: they assume one credentialing file means one contract, or they assume five plans means five sets of verification. Neither is true.

Step 1: Enroll With Texas Medicaid Through PEMS

Every provider who wants to see Texas Medicaid or CHIP members has to enroll with Texas Medicaid first, through PEMS on the TMHP site. Groups enroll, and each rendering clinician enrolls and is linked to the group. Health plans check Medicaid enrollment before they’ll move a credentialing file forward, so this step sets the pace for everything else.

Texas has been building MCO credentialing into PEMS as well, under a project called PEMS+. The rollout was postponed in 2025 and launched first for facility providers in a soft launch. Before you start, check TMHP’s current notices to see whether your provider type submits credentialing through PEMS or through the CVO process below. Our Medicaid provider enrollment guide covers how state enrollment works in general.

Step 2: Credentialing Through the Centralized CVO

Once you contact an MCO to join its network, the plan sends a work order to the CVO, and the CVO verifies your credentials on behalf of every plan. The steps and timeframes, as TAHP lays them out:

Two deadlines matter most. First, Texas requires MCOs to finish credentialing a new provider and have their claim systems recognize the provider as in network within 90 days of a complete application. The clock starts at “complete,” so an application missing a document doesn’t start it. Second, your attestation is valid for 120 days. If verification drags past that point because something was missing, you’ll be asked to re-attest. The same rule drives the commercial side through CAQH, covered in our guide to what happens when a CAQH attestation lapses.

Step 3: Contract With Each MCO

Credentialing gets you verified; it doesn’t get you paid. Each MCO still needs a signed contract that lists your group, locations, and clinicians, and contracting timelines vary by plan. Texas Medicaid is divided into service areas and programs (STAR, STAR+PLUS, STAR Kids, STAR Health, and CHIP), and which plans you need depends on where your patients live and which programs they’re in.

For behavioral health groups, there’s one more question to ask each plan: who manages its behavioral health network? Some MCOs handle behavioral health contracting themselves, and others delegate it to a behavioral health organization. Ask before you send a contract request, or it can sit with the wrong department for weeks. The same carve-out pattern shows up on the commercial side, as covered in our behavioral health credentialing guide.

The Expedited Credentialing Rule Behavioral Health Groups Should Use

Texas requires Medicaid MCOs to offer expedited credentialing to certain clinicians joining a group that already has a contract with the plan. Under the state rule, the eligible provider types include licensed clinical social workers, licensed professional counselors, licensed marriage and family therapists, and psychologists, along with dentists and dental specialists, while physicians are covered by a separate Insurance Code process.

To qualify, the clinician has to be a member of an established group with a current contract with that MCO, be enrolled in Texas Medicaid, agree to the group’s contract terms, and submit everything the MCO needs to start credentialing. Once they do, the MCO must treat them as in network for Medicaid payment while credentialing finishes. If credentialing ultimately fails, the plan can recover the difference between in-network and out-of-network payment.

Here is what that’s worth with illustrative numbers. A newly hired LPC joins a group that’s already contracted with a STAR plan and sees 15 of that plan’s members a week at an illustrative $75 per session. Waiting out a full 90-day credentialing cycle would hold back about 13 weeks of those sessions, roughly $14,625. Requesting expedited credentialing on day one keeps that revenue in network from the start. The rule only works if the clinician’s Texas Medicaid enrollment is done first, which is one more reason Step 1 can’t wait. The broader new-hire sequence is in our guide to adding a provider without losing revenue.

What About Associate Clinicians in Texas?

Texas Medicaid’s expedited credentialing covers fully licensed LCSWs, LPCs, and LMFTs, not associates. A 2025 bill would have required Texas Medicaid to reimburse LPC Associates, LMFT Associates, and LMSWs directly at 50% of the psychologist rate, but it didn’t pass. That leaves associate billing to each MCO’s own policy, so get each plan’s answer in writing before scheduling an associate with its members. The payer-by-payer logic is the same one we lay out in our guide to billing pre-licensed clinicians.

Keeping Texas Enrollment Active

Texas runs two maintenance clocks that don’t line up, and missing either one stops payment.

TMHP revalidation. Texas Medicaid enrollment has to be revalidated at least every five years, and some providers more often based on risk. HHSC asks for the revalidation at least 120 days before the enrollment period ends. Miss it and the provider is disenrolled from Medicaid and can’t be paid.

CVO recredentialing. Recredentialing runs every three years and is consolidated, so you recredential once for all Medicaid MCOs. If your effective dates differ by plan, the due date follows the earliest one, and the CVO notifies providers at least 180 days ahead. That notice goes to the contact information on file, so keep it current.

Put both dates for every clinician on one calendar, along with CAQH re-attestation if your commercial payers use it. Our re-credentialing deadline guide shows how to track them across a roster.

Expanding Into Texas Without Losing the First Quarter

Texas rewards groups that run its three tracks in parallel and use the rules written for them. Mark Wood, our COO, has spent more than 20 years watching groups lose months in multi-plan Medicaid states by waiting for one step to finish before starting the next. In Texas, the enrollment, the CVO file, and the contract requests can all move at once.

MedBillingTech handles Texas Medicaid enrollment, CVO credentialing, MCO contracting, and expedited credentialing requests at a flat $150 per application.
