Frequently Asked Questions (FAQs)
What are my prescription drug benefits?
Your prescription drugs are a benefit through your Texas STAR / CHIP coverage, as long as you go to a drug store in Texas Children's Health Plan network. There are some medicines that may not be covered through Medicaid / CHIP. A Texas Children's Health Plan network drug store can let you know which medicines are not covered, or help you and your doctor find another medicine that is covered. You can also ask your doctor or clinic about what medicines are covered, and what is best for you.
How do I get my child's medicines? Who do I call if I have problems getting my child's medicines?

What formulary (list of medicines) will Navitus use?
Texas STAR and CHIP formularies are provided by the Texas VDP and are used for STAR and CHIP members. Information about the drugs on the Texas VDP Formulary and the associated PDL can be found here.
Where can I find the list of drugs that need pre-approval?  Where do I find the Texas Children's Health Plan clinical edit criteria for pre-approval? 
What is a clinical edit? How is it handled?
Clinical edits are rules that let us review a member's medical and drug claims history. The Texas VDP sets the criteria for clinical edits. If a patient does not meet the guidelines, then pre-approval will be required. If a patient does meet the guidelines, based on past medical and drug claims,  the prescription will be approved without pre-approval.
What is a quantity limit? How is a quantity limit handled?
A quantity limit may lower the number (or amount) of drugs a patient can get during a certain time period. Quantity limits put a limit on the use of certain drugs for quality and safety reasons. The quantity limit for each drug is supported by the Food and Drug Administration (FDA) and by the instructions in the package insert. This program helps encourage the right drug use. If a quantity limit is given to a drug, and the prescription is higher than this quantity limit, the local pharmacist will make sure the request is safe. If the higher amount or dose of the drug is considered safe, a supply of up to 15 days will be given. The provider will contact Navitus to get approval for any request of the larger quantity.
What is step therapy? Are rules included for Texas Children's Health Plan Medicaid patients?
Step therapy is a program that ensures the most effective use of prescription drugs for patients. A step therapy plan starts with the most appropriate drug therapy based on national published guidelines.  If those treatments do not work, other alternative treatments are considered.
How are generic substitutes handled?
The Texas VDP has a list of drugs on the PDL. A drug that is covered by this PDL may be brand or generic. The brand and its generic are normally not both covered. The generic substitution will not happen because only one drug will be covered by the Texas VDP PDL. Your doctor will look up your medicine on the Texas VDP PDL to make sure it is covered.
What is therapeutic interchange?
Therapeutic interchange is when drugs are prescribed that are chemically different, but therapeutically similar. Therapeutic interchange is used to control costs and should be approved by a prescriber. Texas Children's Health Plan will not deny coverage of any product covered under the Texas VDP. Texas Children's Health Plan may contact your provider to help you understand the Texas VDP formulary and all of the other options available for you. Any changes to your medicine should only be made with your doctor's consideration.
Who can issue prior authorizations for medicines?
Navitus is responsible for handling pre-approval requests for all drugs requiring prior authorization.
