What is acute psychiatric inpatient treatment?

Acute psychiatric inpatient treatment is provided in a community hospital or a certified freestanding Evaluation and Treatment facility (E&T).
For publicly funded services, a medical necessity determination is made by the RSN/PIHP or Designated Mental Health Professional (DMHP). For privately funded services, the individual's insurance company makes that determination. The length of stay in the hospital is variable, depending upon the individual's needs.
