How is the Vendor Drug Program used for Superior Medicaid Members?

US Script is the exclusive Provider for pharmacy services for Superior Medicaid Members. The Vendor Drug Program will continue to provide pharmacy benefits for Medicaid Members served by traditional Medicaid. The Texas Vendor Drug program does supply the Texas Medicaid Preferred Drug List (PDL) and Clinical Edit criteria that are utilized by US Script to provide benefits for Superior Medicaid Members.

Do pharmacies and prescribers contact Superior for pharmacy questions about prior authorizations, clinical edits, quantity limits or regarding claims?

No. Superior is contracted with US Script, which is our PBM. A PBM is a company that manages and administers pharmacy benefits. Providers may call US Script to inquire about prior authorizations, clinical edits, quantity limits or to request a peer-to-peer review with a US Script Pharmacist. Pharmacies should refer to the US Script help desk for assistance with all non-Medicare claims. Pharmacies should refer to the Argus help desk for assistance with claims for Medicare.

How do I contact Argus as a pharmacist with a Medicare Advantage claim concern?

Argus will assist local pharmacy staff directly with questions regarding claims. Call 1-877-935-8021.

What pharmacies does US Script have contracts with?

US Script has contracted with more than 95% of the current Vendor Drug Program pharmacy Providers in Texas. The US Script pharmacy network includes the national chain pharmacies (e.g. Walgreen’s, CVS, HEB, Wal-Mart, Target, and Randall’s), as well as a large number of independent pharmacies. US Script’s pharmacy network can be accessed online at, or by calling Superior’s Member Services Department. It is important to note that any pharmacy providing services for Superior Medicaid Members must be a Vendor Drug Program participant plus be contracted by US Script.

How is a Medicaid Member’s prescription processed if out-of-state?

Any pharmacy providing services for Superior Medicaid Members must be a Vendor Drug Program participant plus be contracted by US Script. If you are an out-of-state pharmacy Provider please contact the Texas Vendor Drug Program directly to become a VDP pharmacy Provider and also contact US Script to contract with our PBM.

What formulary will US Script use?

Texas Medicaid and CHIP formularies are provided by the Texas Vendor Drug Program and are used for Medicaid and CHIP Members. US Script uses the Ambetter formulary for Ambetter Members. US Script and its contracted claims processor (Argus) use the Medicare Advantage formulary for Advantage Members. All formularies are posted on our Superior HealthPlan website.

Where can I find the formulary and list of drugs requiring prior authorization? Where do I find Superior Medicaid Clinical Edit criteria?

What is a quantity limit? How is a quantity limit handled?

A quantity limit may reduce the number (or amount) of drugs covered within a certain time period. Quantity limits are designed to limit the use of selected drugs for quality and safety reasons. The quantity limit for each drug is supported by FDA-recommended use of the product and per approved dosing instruction in the package insert. This utilization management program encourages appropriate drug use. If a quantity limit is programmed for a medication and the prescription is outside of this predetermined quantity limit the local pharmacist will review the original request for safety. If the drug is deemed safe at this higher dose/quantity a supply of up to 15 days will be dispensed. The Provider should contact US Script to request a prior authorization approval for this dose to fulfill any balance request of the larger quantity per day supply.

What is step therapy? Are step therapy edits included for Medicaid patients?

Step therapy is an approach to prescription coverage intended to control the costs and risks posed by prescription drugs. A step therapy edit starts with the most cost-effective and safest drug therapy and progresses to other more costly or less safe therapies only if necessary. Currently, the Texas Vendor Drug Program PDL is enforced for Medicaid Members. Step Therapy edits are not part of the Texas Vendor Drug Program at this time.

How is generic substitution handled?

The Texas Vendor Drug Program has a list of preferred medications on the Preferred Drug List (PDL). A drug that is covered under this PDL may be either brand or generic. Both the brand and its available generic generally are not both covered. Thus, generic substitution does not occur since only one product will be the covered entity. The prescriber is encouraged to reference the Vendor Drug Program when prescribing medication for the most up-to-date, covered medication entity.

What is Therapeutic Interchange?

Therapeutic interchange involves the dispensing of medications which are chemically different, but therapeutically similar in nature. Therapeutic interchange generally occurs for cost control and under the approval of a prescriber. We do not refuse coverage of any covered product under the Texas Vendor Drug Program in lieu of a similar covered product for cost control reasons. We may, however, contact the Provider to provide education on the Texas Vendor Drug Program formulary and all of the covered alternatives available for Members. Any changes to medication at any time should only be made under the Provider’s careful consideration.

Who will be responsible for issuing prior authorizations for medications?

US Script is responsible for receipt and processing of prior authorization requests for medications to be dispensed through a pharmacy that are non-preferred on the Medicaid Preferred Drug List (PDL). US Script is also responsible for processing all authorization requests for review of exceptions to clinical edits or quantity limits applied. US Script will also process prior authorization for exceptions to Part D Medicare prescriptions. Non-preferred products on the Ambetter formulary requiring prior authorization are also handled by US Script. Superior HealthPlan retains responsibility for prior authorization of medication not dispensed through a pharmacy. These medications are most often billed by physician offices using HCPCS-J-codes. Superior HealthPlan Pharmacy Department is responsible for processing prior authorization of all HHSC specialty drugs cross-referenced to the Texas provider’s manual. The health plan pharmacy department also reviews all Synagis prior authorization requests. These medications are filled by our preferred specialty pharmacies: AcariaHealth or CVS/Caremark, except when there are cases of limited drug distribution.

How do I request Prior Authorization for Durable Medical Equipment/Medical Supplies?

The Texas Vendor Drug Program has a limited home health supplies list and many items such as insulin syringes and test strips are included in this coverage. The products are billed at a retail pharmacy via US Script, our PBM. A link to this information can be found at  Covered Durable Medical Equipment/Medical Supplies may be obtained through a Superior HealthPlan participating Provider. To request a prior authorization from the Superior DME Prior Authorization Department please call 1-800-218-7508 ext. 53227.

How is a Medicaid COB edit (POS 41) occurring at point of sale?

COB is the coordination of benefits for members who have other coverage in addition to Medicaid. When eligibility files indicate a Member has other coverage and attempts to fill at retail, the POS 41 message ‘SUBMIT BILL TO OTHER PROCESSOR OR PRIMARY PAYOR’ will occur.

This message should be addressed at the local pharmacy by doing the following:

  1. Retail pharmacy will ask Member for the alternate insurance card, enter and process the claim under the other insurance.
  2. If Member does not have any other insurance or indicates this other coverage is no longer effective a retail pharmacy will contact the US Script Help Desk for an override for COB.
  3. After the override, the Member will be mailed a letter asking that the member please correct the eligibility status with the local Medicaid office.
  4. Member will contact Medicaid office directly to remove the other insurance from the account or COB edits may continue to fire.
