Every day your Texas Medicaid enrollment is delayed costs your practice an average of $250 per provider in unbillable services. The Texas Medicaid & Healthcare Partnership (TMHP) manages provider enrollment through the Provider Enrollment and Management System (PEMS) — a portal-driven process with strict documentation requirements, statutory compliance thresholds, and a secondary MCO credentialing layer that catches most practices off guard.
This guide walks you through the complete TMHP enrollment process from account creation to active billing status, including the exact documents you need, out-of-state exception criteria, common denial codes, and the critical MCO credentialing step that most generic guides completely miss.
What Is TMHP and Why Does It Matter?
TMHP (Texas Medicaid & Healthcare Partnership) is the fiscal agent contracted by the Texas Health and Human Services Commission (HHSC) to administer the Texas Medicaid and CHIP programs. All provider enrollment, claims processing, and provider communications flow through TMHP. You cannot bill Texas Medicaid without first completing enrollment through their PEMS portal.
TMHP manages enrollment for over 85,000 active Texas Medicaid providers. The average processing time for a clean application is 30–45 days, but incomplete submissions routinely extend this to 90+ days due to documentation corrections and resubmission cycles.
Step-by-Step TMHP Enrollment Process via PEMS
The PEMS (Provider Enrollment and Management System) portal is the only way to enroll in Texas Medicaid — there is no paper application option. Follow these six steps in exact order to submit a clean application and avoid the resubmission cycles that delay most providers by 60+ days.
Create Your TMHP User Account
Navigate to tmhp.com and create a TMHP User Account. You will need your email address, NPI number, and Tax ID. If you already have an account from a previous enrollment or revalidation, log in with your existing credentials — PEMS will link automatically to your NPI.
Access PEMS and Select Your Application Type
Once logged in, access the Provider Enrollment and Management System (PEMS). Select the appropriate application type: New Enrollment, Re-enrollment, or Revalidation. PEMS will dynamically generate a checklist of required documents based on your provider type (individual, group, facility) and the programs you are enrolling in.
Verify Taxonomy Codes Before Starting Attestation
Critical pre-step: Before beginning the online attestation process, verify the taxonomy code associated with your provider type and specialty. TMHP is unable to publish taxonomy descriptions in the PEMS portal due to copyright restrictions on the NUCC taxonomy code set. You must independently confirm your correct taxonomy code at nucc.org before proceeding — an incorrect taxonomy code will cause enrollment rejection or downstream claim denials.
Complete Provider Information Sections
Fill out all required sections in sequential order: provider demographics, practice location(s), specialty designations, license information, ownership disclosures, and billing/payment details. PEMS enforces a strict sequential workflow — each section must be completed before you can proceed to the next.
Upload All Required Documents
Upload every document from the PEMS-generated checklist. Accepted formats: PDF, JPG, TIF, PNG, DOC/DOCX, XLS/XLSX, or RTF. Maximum file size is 50MB per file. Ensure every document is current, legible, and matches the information entered in your application exactly.
Sign the Texas Medicaid Provider Agreement
Electronically sign the Texas Medicaid Provider Agreement with HHSC. This is a binding contract that obligates you to comply with all Texas Medicaid billing rules, documentation requirements, and audit cooperation standards.
Submit and Track Your Application
Review all sections for accuracy, then submit. PEMS generates a confirmation number — save this immediately. Use the PEMS dashboard to track your application status. Follow up with the TMHP Contact Center at 1-800-925-9126 (Mon–Fri, 7 AM–7 PM CT) every 7–10 business days if your status shows “Pending” for more than 30 days.
✓ Pro Tip: You can save your application as a draft at any point and return later. Do not rush to submit with missing documents — incomplete applications are the #1 cause of enrollment delays and account for over 85% of initial rejections.
Complete Document Checklist for TMHP Enrollment
The exact documents required depend on your provider type, but every Texas Medicaid enrollment requires the following core documentation. Missing even one of these will trigger a rejection and reset your processing timeline.
| Document | Details & Requirements |
|---|---|
| National Provider Identifier (NPI) | Valid 10-digit NPI. Must be active in NPPES and match your application exactly. |
| Texas State License / Certification | Current, unrestricted license to practice in Texas. Must not be expired at time of submission. |
| DEA Registration | Required for prescribing providers. Must be active and match practice address. |
| Board Certification | If applicable to your specialty. Must be from an ABMS or AOA-recognized board. |
| W-9 Form | IRS Request for Taxpayer Identification Number. Must match your legal entity name and TIN exactly. |
| IRS CP-575 or EIN Confirmation | Official IRS documentation confirming your Employer Identification Number. |
| Franchise Tax Account Status Page | From the Texas Comptroller. Required for all incorporated entities. Must show “Active” status. |
| Certificate of Formation / Incorporation | Filed with the Texas Secretary of State (or home state + Certificate of Authority for out-of-state entities). |
| Professional Liability Insurance | Current malpractice insurance certificate showing coverage amounts and effective dates. |
| Voided Check or Bank Letter | For Electronic Funds Transfer (EFT) setup. Must match the TIN on your W-9. |
| Principal Information Form (PIF-2) | Required for each owner with 5%+ interest, managing employee, and authorized official. Must include SSN and DOB. |
| Disclosure of Ownership Form | Lists all individuals and entities with ownership or control interest in the provider entity. |
| CLIA Certificate | Required only if performing laboratory services. |
| Facility License | Required for facilities (hospitals, ASCs, nursing facilities, etc.). |
| Immigration Documentation | Required for non-U.S. citizen providers. |
| State of Texas Medicaid Provider Surety Bond Form | Required for certain provider types at enrollment or re-enrollment. Must include original signatures plus a separate Power of Attorney document from the issuing surety company. Note: This is completely separate from any CMS Surety Bond. |
&warning; Critical: Every document must match. If your W-9 says “Smith Medical Group LLC” but your NPI registry says “Smith Medical Group,” TMHP will reject your application. Verify exact name matching across your IRS documents, NPPES registry, and PEMS application before submitting.
Out-of-State Provider Enrollment: “Good Cause” Exceptions
Out-of-state providers cannot freely enroll in Texas Medicaid. You must document that you meet at least one statutory “Good Cause” exception to be eligible:
| Exception | Required Documentation |
|---|---|
| Medical Emergency | Written documentation by the attending physician detailing the acute nature of the emergency |
| Health Endangerment | Clinical proof that requiring the patient to travel to Texas would actively endanger their health |
| Customary Practice | Evidence that a specific Texas border locality customarily uses medical resources in the neighboring state |
| Dually Eligible Recipients | Proof of medical necessity for a patient enrolled in both Medicare and Medicaid (crossover claims only) |
| Limited Distribution Drugs | Signed letter from provider and FDA confirming the pharmacy distributes an FDA-classified limited distribution drug |
| Network Reliance | Written proof that existing Texas Medicaid-enrolled providers directly rely on the applicant’s specialized services |
| Existing MCO Agreement | Documentation that the provider maintains a participating agreement with a Texas Medicaid MCO and enrollment leads to more cost-effective care delivery |
| Laboratory Exception (In-State Classification) | A laboratory may participate as an in-state provider regardless of physical location if it (or a parent/subsidiary company) maintains operations in Texas and collectively employs at least 1,000 people within the state |
Out-of-state incorporated entities face additional burdens: you must provide a notarized Corporate Board of Directors Resolution Form with original signatures, a Certificate of Authority from the Texas Secretary of State, and a Franchise Tax Account Status Page from the Texas Comptroller.
The MCO Credentialing Trap: Why TMHP Approval Alone Is Not Enough
Completing TMHP enrollment does NOT authorize you to bill Texas Medicaid Managed Care Organizations (MCOs). This is the single most devastating pitfall in Texas Medicaid enrollment. Texas operates primarily through managed care — the majority of Medicaid beneficiaries are enrolled in MCOs.
After receiving your TMHP approval, you must separately contact and credential with each MCO you want to bill:
- Superior HealthPlan (Centene subsidiary)
- Amerigroup Texas (Elevance Health)
- UnitedHealthcare Community Plan
- Molina Healthcare of Texas
- Texas Children’s Health Plan
- Dell Children’s Health Plan
- Community Health Choice
Each MCO has its own credentialing application, committee review schedule, and approval timeline. This effectively doubles your total enrollment timeline from 30–45 days to 60–120 days before you can actually bill and collect revenue.
Common TMHP Denial Codes and How to Resolve Them
TMHP uses both standard CARC/RARC adjustment codes and proprietary “EX” denial codes unique to Texas Medicaid. If your claims are denying after you’ve submitted an enrollment application, these are the specific codes you will encounter — including the TMHP-exclusive EX codes that generic billing references do not cover:
| Code | Meaning | Resolution |
|---|---|---|
| EX0Q | Billing provider not enrolled with TX Medicaid | Immediately initiate PEMS enrollment. This code confirms TMHP has no active record for your provider ID. Claims will continue denying until enrollment is fully approved. |
| EX*1 | Superior HealthPlan (SHP) guidelines for submitting a corrected claim were not followed | Review the SHP-specific corrected claim submission protocol. Resubmit using the exact format and replacement code required by Superior HealthPlan. |
| EX07 | The procedure code is inconsistent with the patient’s sex | Verify the patient’s sex parameter in your claim matches their Medicaid eligibility file. Correct and resubmit. |
| N767 | Provider not enrolled in the Medicaid program of the state where the member is covered | Complete PEMS enrollment immediately. This remark code confirms the provider lacks active Texas Medicaid enrollment. |
| CO-4 | The procedure code is inconsistent with the modifier used | Verify correct modifier usage per TMHP billing guidelines for your specialty. |
| CO-197 | Precertification/authorization/notification absent | Obtain prior authorization from the appropriate MCO before rendering services. |
| PR-1 | Deductible amount | Bill the patient for their cost-sharing responsibility per their Medicaid plan terms. |
| CO-109 | Claim not covered by this payer | Verify the patient’s MCO assignment. You may be billing the wrong MCO. |
| CO-16 | Claim lacks information needed for adjudication | Review the 835 remittance for specific missing data fields and resubmit with corrections. |
&warning; 365-Day Filing Deadline: TMHP enforces a strict 365-day filing deadline calculated from the date of service for outpatient claims, or specifically from the discharge date for inpatient claims. Out-of-state providers are held to this same deadline. If you cannot complete enrollment and submit claims within this window, the revenue is permanently forfeited — TMHP does not grant extensions or exceptions regardless of enrollment processing delays.
Frequently Asked Questions
How long does TMHP provider enrollment take?
A clean, complete application submitted through PEMS typically processes in 30–45 days. Incomplete applications can take 90+ days due to correction cycles. Add another 30–60 days for MCO credentialing after TMHP approval.
Can an out-of-state provider enroll in Texas Medicaid?
Yes, but only if you meet one of the statutory “Good Cause” exceptions (medical emergency, health endangerment, customary practice, dual eligibility, limited distribution drugs, or network reliance). You must provide documentation proving your exception with your PEMS application.
What is the difference between TMHP enrollment and MCO credentialing?
TMHP enrollment registers you as a Texas Medicaid provider at the state level. MCO credentialing is a separate process where you contract with individual Managed Care Organizations (Superior HealthPlan, Amerigroup, etc.) to bill their enrolled members. You need both to collect revenue from most Texas Medicaid patients.
What file formats does PEMS accept for document uploads?
PEMS accepts PDF, JPG, TIF, PNG, DOC/DOCX, XLS/XLSX, and RTF files. Maximum file size is 50MB per document.
What happens if I miss the 365-day filing deadline?
Revenue for services rendered more than 365 days ago is permanently forfeited. TMHP does not grant extensions. This makes timely enrollment critically important for providers who have already begun seeing Texas Medicaid patients.
