Pharmacy Programs

These pharmacy programs are available for members.

Prior Authorization/Step Therapy Program

The prior authorization/step therapy program is designed to encourage safe, cost-effective medication use.

This program may be part of your prescription drug benefit plan. To find out if your specific benefit plan includes the prior authorization/step therapy program, and which drugs are part of your plan, refer to your benefit materials, or call the number on the back of your ID card.

Prior Authorization

Under this program, your doctor will be required to request pre-approval, or prior authorization, through Blue Cross and Blue Shield of Texas in order for you to get benefits for the select drugs.

More information is available in the prior authorization member flier PDF Document.

Step Therapy

The step therapy program requires that you have prescription history for a "first-line" medication before your benefit plan will cover a "second-line" drug.

  • A first-line drug is recognized as safe and works well in treating a specific medical condition, as well as being a cost-effective treatment option.
  • A second-line drug is a less-preferred or likely a more costly treatment option.

Step 1: If possible, your doctor should prescribe a first-line medication right for your condition.

Step 2: If you and your doctor decide that a first-line drug is not right for you or is not as good in treating your condition, your doctor should submit a prior authorization request for coverage of the other drug.

More information is available in the step therapy member flier PDF Document.

If you have questions about the prior authorization/step therapy program, call the number on the back of your BCBSTX ID card.

Specialty Pharmacy Program

Your prescription drug benefit may include a specialty pharmacy program through Prime Therapeutics Specialty Pharmacy (Prime Specialty Pharmacy).

Specialty medications are those used to treat serious or chronic conditions. Examples include hepatitis C, hemophilia, multiple sclerosis and rheumatoid arthritis. These drugs are typically given by injection, but may be topical or taken by mouth. They often require careful adherence to treatment plans, have special handling or storage requirements, and may not be stocked by retail pharmacies.

When you purchase specialty medications through Prime Specialty Pharmacy, you can have your self-administered specialty medications delivered directly to you, or to your doctor's office. You also receive at no additional charge:

  • Support services for managing your drug therapy
  • Educational materials about your particular condition
  • Help with managing potential medication side effects
  • 24/7/365 customer service phone access

BCBSTX members who use oral oncology or hemophilia specialty drugs may have other in-network specialty pharmacy options. Log in to your Blue Access for MembersSM account to find a preferred specialty pharmacy near you.

Note: Prime Therapeutics Specialty Pharmacy LLC (Prime Specialty Pharmacy) is a wholly owned subsidiary of Prime Therapeutics LLC, a pharmacy benefit management company. BCBSTX contracts with Prime Therapeutics to provide pharmacy benefit management, prescription home delivery and specialty pharmacy services.
