Medicaid and CHIP Formulary and Medicaid Preferred Drug List (PDL)
Texas Vendor Drug Program Clinical Edits
These clinical prior authorizations apply to patients enrolled in traditional Medicaid. Texas Vendor Drug Program Clinical Edits can be viewed on the Vendor Drug Program website .
Providers are encouraged to write prescriptions for preferred products as listed on the Texas Medicaid formulary and Preferred Drug List (PDL), available on the Vendor Drug Program (VDP) website at https://www.txvendordrug.com/formulary/prior-authorization.
If, for medical reasons, a member cannot use a preferred product, providers are required to contact the Pharmacy department at Amerigroup at 1-800-454-3730 to obtain prior authorization. CHIP members’ claims will not require PDL prior authorization.
Medications that require prior authorization may include:
- Drugs listed as nonpreferred on the PDL or drugs that require clinical prior authorization.
- Select self-administered injectable products.
- Drugs that exceed certain cost and/or dosing limits. (For information on these limits, call Amerigroup Pharmacy at 1-800-454-3730.)
Note: This list is not all-inclusive and is subject to change.

Clinical Pharmacy Policies
Drug coverage policies are based on medical necessity considerations subject to applicable benefits. These policies assist with medical necessity coverage decisions, may include state-specific guidance regarding coverage and do not constitute medical advice. Benefit determination is based on the applicable contract language and/or state requirements.
These policies are not a guarantee of coverage. Contract language or state requirements will prevail when there are conflicts with any medication coverage policy. In all cases, Medicaid contracts or CMS requirements supersede policy criteria.
