Prior Authorization : Services Requiring Prior Authorization

Topic #6119

Central Nervous System Assessments and Tests

PA is not required for central nervous system assessments and tests. Central nervous system testing may be part of the mental health evaluation, but it does not require PA and must be billed under the appropriate codes.

Topic #6120

Health and Behavior Assessments and Interventions

Up to eight units per DOS of any combination of health and behavior assessment and intervention services may be coverable.

Psychiatrists and APNPs with a psychiatric specialty providing health and behavior assessment and intervention services should refer to the Physician service area for information related to E&M and preventive medicine services.

Providers may not report health and behavior assessment and intervention services in conjunction with psychiatric diagnostic procedures or psychotherapy on the same date.

  • Adult mental health day treatment (procedure code H2012 with modifiers HE [mental health program] and U6 [functional assessment])
  • Substance abuse day treatment (procedure code H2012 with modifiers HF [substance abuse program] and U6 [assessment])
  • Additional assessment hours beyond the eight hours every rolling 12 months requires PA. Providers may request additional assessment hours beyond the PA limit by submitting the PA/EA along with the PA/RF.
Topic #3755

Services Requiring Prior Authorization

The majority of mental health and substance abuse services do not require PA. Some higher intensity mental health and substance abuse services require PA before they are provided.

Wisconsin Medicaid does not reimburse providers for services provided either before the grant date or after the expiration date indicated on the approved PA/RF. If the provider delivers a service either before the grant date or after the expiration date of an approved PA or provides a service that requires PA without obtaining PA, the provider is responsible for the cost of the service. In these situations, providers may not collect payment from the member.

PA does not guarantee payment. To receive Medicaid reimbursement, provider enrollment and member eligibility on the DOS, as well as other Medicaid requirements, must be met.

The following table lists mental health and substance abuse services that require PA and, for those services requiring PA, maximum grant period allowed for PA, required PA forms, and maximum backdating allowed when specifically requested.
