The Texas Vendor Drug Program provides statewide access to covered outpatient drugs for eligible individuals enrolled in the following programs:
- the Children’s Health Insurance Program (CHIP)
- the Children with Special Health Care Needs (CSHCN) Services program
- the Texas Healthy Texas Women (HTW) Program
- the Kidney Health Care (KHC) Program
Pharmacy providers must enroll with Texas Medicaid prior to providing outpatient pharmacy prescription services, and must be enrolled prior to participating in any Medicaid managed care pharmacy networks.
All traditional Medicaid (fee-for-service) outpatient prescription claims are processed through a real-time, point-of-sale system using the National Council for Prescription Drug Programs (NCPDP) telecommunication standard format. All claim submission requirements are available in the Pharmacy Provider Procedure Manual (PPPM). Payment is posted weekly. Pharmacy staff can also use our electronic eligibility verification tools to obtain prescription benefit information and managed care plan coverage. The claim system undergoes regularly scheduled weekly maintenance between 11 p.m. Saturdays and 1 a.m. Sundays (central time). Pharmacy staff will be unable to submit claims during this time. Notification of extended or expanded maintenance periods will be sent to pharmacy providers. Not receiving our notices? Pharmacy staff should ensure their enrollment information is current and report any changes.
HHS is available to assist pharmacy providers with claim submittal status and information regarding program policies and procedures. Pharmacy staff and other stakeholders receive program updates through our newsletter and email notification service.
The cost for drug prescriptions in the Texas Medicaid program is shared by the federal government and the state. In order for Texas to receive federal funds assistance for prescription claims, any drugs prescribed must be produced by a drug manufacturer that participates in the Centers for Medicare & Medicaid Services (CMS) drug rebate program. In return for having their drugs covered by state Medicaid programs, the manufacturer agrees to pay rebates according to their state and federal contracts. HHS oversees the collection of these rebates from drug manufacturers. Federal and state-only drug rebate programs in which Texas participates include the Medicaid Drug Rebate Program; the Supplemental Medicaid Drug Rebate Program; the CHIP Drug Rebate Program; the CSHCN Drug Rebate Program; and the KHC Drug Rebate Program.
