Influenza Vaccines

Traditional Medicaid

During influenza season, pharmacies may bill for influenza vaccines provided to people seven and older in a pharmacy setting for influenza vaccines available on the Medicaid formulary as part of the pharmacy benefit. The pharmacist administering the vaccine does not have to enroll with TMHP but must follow the Texas State Board of Pharmacy's (TSBP) rules related to certification to immunize and vaccinate. Refer to TAC Section 295.15 (Chapter 295: Administration of Immunizations or Vaccinations by a Pharmacist under Written Protocol of Physician).

Administering pharmacists are health care professionals licensed by the TSBP to practice as a pharmacist, have met and maintained the eligibility requirements outlined in law, and have been certified by the TSBP to administer vaccines.

Administering pharmacists are under the supervision of a physician under state law and may administer immunizations or vaccinations only under a physician’s written protocol authorizing the administration. Pharmacists are employed and remunerated by a pharmacy for their services. If the program’s services are covered and reimbursable, payment may be made to the pharmacy employing the licensed pharmacist. HHSC will reimburse pharmacies for the ingredient costs and applicable administration fees.
