Discharge criteria

Discharge when any one of the following criteria is sufficient.

Discharge from acute psychiatric intensive care

Lower or different level of care is appropriate: The member no longer meets continuing-stay criteria for acute psychiatric intensive care but meets admission criteria for general inpatient mental health services or another safe level of care.
Goals met and continuing care arranged: Treatment-plan goals and objectives have been substantially met and/or a safe continuing-care program can be arranged and implemented at a less-intensive level of care.
No expected progress: The member is not progressing toward treatment goals and there is no reasonable expectation of progress at this level of care.
Chronic condition requires long-term care:

Coverage is excluded when the member can be safely maintained and effectively treated at a less-intensive level of care rather than acute psychiatric intensive care.

Coverage is excluded when the member has serious and persistent mental illness but is not experiencing an acute exacerbation of that illness.

Coverage is excluded when the primary issue is social, legal, or medical without a concurrent major psychiatric episode meeting criteria for this level of care. Coverage is also excluded when admission is being used as an alternative to incarceration, justice-system involvement, respite, or housing.

Coverage is excluded when a medical condition requires treatment in a medical or surgical setting, regardless of the member’s psychiatric presentation.

Coverage is excluded when medical comorbidities cannot be safely managed in the specialty psychiatric setting.

Prior Authorization

Prior Authorization Required

Prior authorization is required for acute inpatient psychiatric intensive care services before services are provided.

Documentation Required

Clinical Necessity Documentation

Document that the member meets all applicable clinical-necessity requirements for acute intensive psychiatric care, including age, diagnosis, current risk, complexity, and the need for enhanced resources.

Member is between 18 and 64 years of age.
Member has a serious mental illness as defined in Iowa Administrative Code 441—subrule 77.47(1).
Member has a current, severe, and imminent risk of serious harm to self or others.
Document additional complexity of need related to at least one of the following: complex comorbidities (including intellectual or developmental disability, autism spectrum disorder, substance use disorder, or traumatic brain injury); history of clinical-risk violence or current aggression secondary to mental illness; rejected transfer request due to symptom severity; lack of responsiveness to typical interventions or treatment-refractory condition; disorganized psychotic state or manic thought process impairing function or safety; significant disruption to the unit milieu; high elopement risk; or another atypical reason the treating mental health provider determines additional resources are needed for safety.

Background

Acute psychiatric intensive care is intended for rapidly developing, severe psychiatric conditions that require emergency treatment and intensive psychiatric services beyond the capabilities of a general inpatient psychiatric unit. It provides 24-hour skilled nursing, daily medical care, structured milieu treatment, multidisciplinary assessment, enhanced staffing, and increased capacity for observation or intervention. The clinical goal is acute stabilization followed by transition to a general inpatient psychiatric unit or another less-intensive level of care.

Disorganized psychotic state or manic thought process impairing function or the safety of the patient or others.

Milieu disruption: Behavior significantly disrupts the general unit milieu.

Elopement risk: High elopement risk.

Other atypical safety need: Any other atypical reason the treating mental health provider believes additional resources are needed to keep the member and others safe.

Complex illness interventions: Interventions are documented to address acute complex mental illness and comorbidities.

Safety protocols are in place to address physical risk to staff, other patients, or infrastructure.

Elopement precautions: Elopement risk precaution protocol is in place.

The acute psychosis phase has passed, the member no longer meets inclusion criterion 3, and high-intensity services are needed because of a chronic condition requiring transfer to long-term care.

Document the need for acute intensive psychiatric care requiring increased or specialized staffing, equipment, or facilities, supported by at least two of the following: fall precautions; restraints or seclusion-room requirements; assistance with activities of daily living; complex nursing care; acutely impaired cognitive functioning from baseline; interventions addressing acute complex mental illness and comorbidities; safety protocols addressing physical risk to staff, patients, or infrastructure; or elopement-risk precautions.

Denial Risk

Lower Level of Care Is Sufficient

Coverage is excluded when the member can be safely maintained and effectively treated at a less-intensive level of care.

Denial Risk

No Acute Exacerbation

Coverage is excluded when the member has serious and persistent mental illness but is not experiencing an acute exacerbation.

Denial Risk

Nonpsychiatric or Custodial Purpose

Coverage is excluded when the primary purpose is social, legal, medical, or custodial rather than treatment of a concurrent qualifying psychiatric episode.

Do not use admission as an alternative to incarceration or the justice system, or for respite or housing, without a concurrent major psychiatric episode meeting criteria for this level of care.

Denial Risk

Medical Acuity Exceeds Setting

Coverage is excluded when a medical or surgical setting is required, or when medical comorbidities cannot be safely managed in the specialty psychiatric setting.

Denial Risk

Behavioral Dyscontrol Without Qualifying Psychiatric Crisis

Coverage is excluded for exclusive behavioral dyscontrol associated with traumatic brain injury, intellectual disability, pervasive developmental disorder, dementia, or another medical condition when there is no acute crisis related to a diagnosis in the current Diagnostic and Statistical Manual of Mental Disorders.
