Pharmacy and Medical Pre-Certification Help Desk 800-392-8030
Providers can call this toll free number to: request a pre-certification for a radiological procedure (CAT scan and MRI); to initiate an emergency request for an essential medical service or an item of equipment that would not normally be covered under the MO HealthNet program; to request information on Medicare Part D; or, to request a drug prior authorization. The MO HealthNet fax line for non-emergency service or equipment exception requests only is (573) 522-3061; the fax line to obtain a drug prior authorization is (573) 636-6470. Do not use either of these numbers for requests for pre-certifications of MRI and CAT scan procedures.

Effective July 17, 2006, MHD implemented pre-certification for certain radiological procedures (CT and MRI). In order for providers to be reimbursed for these services, the participant must meet certain medical criteria and the physician must obtain the pre-certification for the procedure unless performed in an inpatient hospital or emergency room setting. Approved pre-certification requests are given a 14 day approval period.

The list of medical imaging procedures and durable medical equipment and supplies that currently require pre-certification along with the related medical criteria can be referenced at the MO HealthNet Web site

Before initiating a request, providers are encouraged to sign up for the MO HealthNet web tool - CyberAccess - which automates the pre-certification process. To become a CyberAccess user, contact the ACS Heritage help desk at 1-888-581-9797 or 573-632-9797, or send an e-mail to The CyberAccess tool allows each request for pre-certification to automatically reference the individual participant's claim history, including ICD-9 diagnosis codes and CPT procedure codes. Requests for pre-certification will also be taken by the MO HealthNet call center at 800-392-8030 option 2. Requests must meet medical criteria established by MHD in order to be approved.
