Medicaid Pharmacy Clinical Drug Review Program


The Clinical Drug Review Program (CDRP) is aimed at ensuring specific drugs are utilized in a medically appropriate manner.

Under the CDRP, certain drugs require prior authorization because there may be specific safety issues, public health concerns, the potential for fraud and abuse or the potential for significant overuse and misuse.

Prior Authorization

Prior authorization for PDP drug classes subject to the CDRP must be obtained through a representative at the clinical call center. Prior authorization is required for original prescriptions, not refills. For some drugs subject to the CDRP, only prescribers, not their authorized agents, can initiate the prior authorization process. An authorized agent is an employee of the prescribing practitioner and has access to the patient's medical records (i.e. nurse, medical assistant).

Fax requests for prior authorization are not permitted. Each drug class has specific clinical information that must be provided to the clinical call center before prior authorization will be issued. Prescribers may be asked to fax that information. Clinical guidelines for the CDRP as well as prior authorization worksheets are available online at http://newyork.fhsc.com/providers/CDRP_forms.asp.

The following are subject to the Clinical Drug Review Program prior authorization requirements:
