Investigational and Experimental Treatment

  • Hospitals
  • Participating Physician Groups (PPG)

All participating providers must immediately inform Health Net when there is a request for investigational or experimental treatment. All pertinent documentation for investigational or experimental treatments must be sent to the Health Net Medical Management Department by fax or mail.

In accordance with standards established by the Department of Managed Health Care (DMHC), Health Net has five business days to respond to member requests for review of investigational or experimental treatment. Health Net is required to review all requests for these procedures and is responsible for issuing the denial letter if the treatment is denied.

Health Net's denial letter states the medical and, if applicable, scientific reasons for the denial and any alternative treatment that Health Net does cover. The denial letter also includes an application and instructions for the member to utilize the DMHC Independent Medical Review (IMR) Program.

Participating providers should not direct members to contact Health Net for approval of these services. It is the requesting provider's responsibility to provide all pertinent information and documentation directly to Health Net.

Experimental medical and surgical procedures, equipment and medications, are not covered by Original Medicare or under a Medicare-approved clinical research study. Experimental procedures and items are those items and procedures determined by Health Net and Original Medicare to not be generally accepted by the medical community.
