Page last updated on: 7/17/26

Coverage varies by member plan

Applies to:

Group HMO, EPO, POS and PPO plans

Individual MyPriority® HMO, POS and PPO plans

Medicare Advantage plans

Residential treatment requires 24-hour on-site nursing (RN/LVN/LPN) and 24-hour on-call physician, physician's assistant, advanced practice registered nurse, registered professional nurse or licensed practical nurse under the supervision of a registered professional nurse or physician available to be on site within 30 minutes or notification of emergent health concern. 

Please contact our Behavioral Health Department at 800.673.8043 for purposes of care coordination and access to this level of care.

The term "medical necessity" is care that is determined to be effective, appropriate and necessary to treat a given patient's disorder. To determine medical necessity for mental health residential treatment, the Priority Health Behavioral Health department relies on InterQual® Behavioral Health criteria and Priority Health medical policies:

Authorization is required. In addition to the member meeting medical necessity criteria, the residential program must meet our Residential Facility criteria. We also require ongoing clinical reviews to determine if the member continues to meet medical necessity criteria for treatment.
