Coexisting physical and behavioral health conditions can be difficult to manage. Studies have found that people hospitalized for physical health conditions who also have mental illness are more likely to be readmitted than people who don’t have mental illness.
To help improve health outcomes for our members receiving inpatient care, we encourage hospital staff and attending providers to consider behavioral health evaluations and follow-up care coordination when appropriate. Consider the following tips:
Discuss with our members and their medical teams how medical and behavioral health diagnoses are important and can be intertwined.
Facilitate behavioral health evaluations for our members when they’re admitted to a medical unit for a medical concern and also exhibiting behavioral health symptoms.
Coordinate care with our members’ medical and behavioral health providers and social support to help ensure timely follow-ups. A behavioral health follow-up within 30 days after discharge can be in the form of:
Behavioral health inpatient admission
Partial hospitalization program
Intensive outpatient program
Behavioral health outpatient appointment
Coding for behavioral health evaluation and management: When a member receives a psychiatric consultation while medically inpatient and receives a secondary behavioral health diagnosis, include the following on claims:
The behavioral health diagnosis
The correct Current Procedural Terminology (CPT®) codes for a psychiatric evaluation
