Rational Drug Therapy Program Now Reviews Prior Authorization Drug Requests

Effective July 1, 2005, the West Virginia University School of Pharmacy's Rational Drug Therapy Program assumed review authority for all prior authorization requests for West Virginia Children's Health Insurance Program (WVCHIP).

Contact the West Virginia University School of Pharmacy, Rational Drug Therapy Program, for all prior authorization reviews, at 1-800-847-3859.

The process is typically resolved over the phone. If done by letter the process can take up to two business days.

The following link is for providers who want to print out the Prior Authorization Form to submit to the Rational Drug Therapy Program:  Prior Approval Request Form.

Drugs Requiring Prior Authorization

Several classes of prescription drugs require prior authorization for coverage by WVCHIP.  The prior authorization process will involve the child’s physician and pharmacist communicating with WVU’s School of Pharmacy, Rational Drug Therapy Program (RDTP), about the situation, since these prior approvals are given on a case-by-case basis. The child's doctor must call RDTP.  If your medication is not approved for plan coverage, you will have to pay the full cost of the drug. WVCHIP will cover, and your pharmacist can dispense, up to a five-day supply of a medication requiring prior authorization for the applicable copayment. This policy applies when your doctor is either unavailable or temporarily unable to complete the prior authorization process promptly.

Prior Approval for Medicine for Attention Deficit Hyperactivity Disorder/Attention Deficit Disorder

Prior Authorization Policy - Therapeutic Guidelines 

ADHD medications need prior approval through the Rational Drug Therapy Program (RDTP).  The goals of this therapeutic guideline policy is to promote overall disease management such that medication treatment is supported by adjunctive psychosocial programs, ample patient contact, and frequent follow-up visits throughout the course of therapy to address non-medication treatment alternatives, comorbid disorders, dosage titration, adverse effects, and drug diversion and misuse.

In order to simplify the process for the providers, we have revised an RDTP prior approval form and changed it to specifically address the ADHD/ADD prior approval process.​
