Partial hospitalization programs (PHP) typically last for several weeks, serving as a step-down from inpatient treatment or as an alternative to it. The duration can vary based on factors such as the individual's psychiatric evaluation, stabilization needs, and eligibility for the program. These programs offer intensive, in-person care, often including psychiatric evaluation, case management, family therapy, and other therapeutic interventions tailored to address mental illness. PHP serves as a bridge between inpatient care and outpatient services like intensive outpatient programs (IOP) or ongoing case management. Medicare and Medicaid may cover partial hospitalization for eligible individuals, and referral to a PHP often involves collaboration between inpatient facilities, outpatient providers, and case managers to ensure continuity of care and effective treatment.
