Molecular Diagnostic and Genetic Testing (MD/GT)

Preauthorization of MD/GT is required for commercial (including members with Humana individual products), Medicaid and Medicare Advantage (MA) health maintenance organization (HMO) and preferred provider organization (PPO) members. In Puerto Rico, preauthorization is required for all commercial products. The terms prior authorization, precertification, preadmission and preauthorization all refer to the preauthorization process.

Humana does not review preauthorization requests for the following, as health care providers who participate in an independent practice association (IPA) or other risk network with delegated services need to refer to their IPA or risk network for guidance on processing preauthorization requests:

  • MA members in HMO groups in Florida, Illinois, Nevada, Arizona and California

Please note:

  • For MA Private Fee-for-Service (PFFS) members, preauthorization is not required. Notification is requested for these plans, but not required, as this helps coordinate care for our members.
  • Preauthorization is not required for services provided by nonparticipating health care providers for MA PPO members. Notification is requested, but not required, as this helps coordinate care for our members.

Humana's Genetic Guidance Program

The Genetic Guidance Program is a utilization management initiative designed to share information with physicians and members about the use and appropriateness of MD/GT. Board-certified genetic counselors are available to discuss genetic testing services, and preauthorizations. To initiate a request, you may call 1-800-523-0023. Representatives are available from 8 a.m. to 8 p.m. Eastern time, Monday through Friday.

Submitting preauthorization requests

Physicians and local labs (Puerto Rico only) have several options when submitting their preauthorization requests:
