CVS Caremark, a Pharmacy Benefit Management (PBM) company, administers the pharmacy program for CareSource. Working with CVS Caremark, we maintain a Preferred Drug List (PDL) and quarterly PDL updates.  

Formulary or Preferred Drug List (PDL)

CareSource updates the PDL regularly. Visit the Drug Formulary page for more information.

Generic Substitution

A pharmacy will provide a generic drug if available in place of a brand-name drug. This is called generic substitution. Members and providers can expect the generic to produce the same effect and have the same safety profile as the brand-name drug. If a brand name product is requested when a generic equivalent is available, you will need to request prior authorization. 

Prior Authorization

Some drugs may require prior authorization. Refer to the PDL formulary search tool or the list of drugs that require prior authorization to determine which drugs need prior authorization. 

Prior authorization requests may be submitted online, over the phone or by fax.

Online: Provider Portal

Phone: 1-844-607-2831

Fax: 1-866-930-0019

You may submit requests using the following forms:

Maximum Allowable Cost (MAC)

MAC pricing can be accessed through the secure CVS/Caremark provider portal. MAC Appeals can be completed through the portal and by following the CVS Caremark Appeals Process instructions.

Pharmaceutical Management Procedures

Medications billed on the medical benefit may also require prior authorization. Please check the Authorization Requirements for Medications on the Medical Benefit.​ For all prior authorization decisions (standard or urgent), CareSource provides notice to the provider and member as expeditiously as the member’s health condition requires. Please specify if you believe the request is urgent.

NavigateSite of Care Drug List


CareSource Medicaid pharmacy or medical policies include therapy class policies that are used as a guide when determining health care coverage for our members with benefit plans covering prescription drugs. The policies are written on selected prescription drugs requiring prior authorization or step therapy. The policy is used as a tool to be interpreted in conjunction with the member’s specific benefit plan. Providers can find pharmacy policies for each plan by accessing the policy landing page.

Indiana Opioid Management Policy


CareSource has an exception process that allows the member or the member’s representative to make a request for an exception. Reasons for exceptions may include intolerance or allergies to drugs or inadequate or inappropriate response to drugs listed on the formulary. The member or member’s representative can call Member Services to make the request, or complete the online Member Exception Request for Non-Formulary Medication.

CareSource then reaches out to the provider to obtain the appropriate documentation. CareSource will provide a decision no later than 72 hours after the request is received, or within 24 hours if the member is suffering from a serious health condition. Providers may be asked to provide written clinical documentation as to why a member needs an exception. In determining whether an exception will be given, CareSource will use many sources of information to determine whether approval for the exception will be granted.

Quantity Limits

Some drugs have limits on how much can be given to a member at one time. Quantity limits are based on the approved recommended dose frequencies. Patient safety is also considered.

Step Therapy

Members may need to try one drug before taking another. This is called step therapy. A member must try a medicine on the formulary before a non-formulary drug would be approved by CareSource. Certain drugs will be covered only if step therapy criteria is used.

Therapeutic Interchange

A member might have a drug allergy or intolerance, or a certain drug might not be effective. If a non-formulary agent is requested, the provider will need to submit a prior authorization request. This is called therapeutic interchange.

CareSource provides pharmaceutical management procedures annually and after updates. Changes are made in writing by mail, fax or email or via the web. If you have any questions regarding our pharmaceutical management procedures, please call Clinical Pharmacy Services at 1-877-362-5670.
