Peer Support Services (PSS) are an evidenced-based mental health model of care that provides community-based recovery services directly to a Medicaid-eligible adult beneficiary diagnosed with a mental health or substance use disorder. PSS provides structured, scheduled services that promote recovery, self-determination, self-advocacy, engagement in self-care and wellness and enhancement of community living skills of beneficiaries. PSS services are directly provided by Certified Peer Support Specialists (CPSS) who have self-identified as a person(s) in recovery from a mental health or substance use disorder. PSS can be provided in combination with other approved mental health or substance use services or as an independent service.
