The Collaborative Care Model (CoCM) is an evidence-based model for mental health care that improves access, clinical outcomes, and patient satisfaction with demonstrated efficacy in community health settings and for historically marginalized individuals. Wide-spread implementation is currently limited by sustainability concerns including lack of a reimbursement structure that maintains fidelity to the original model, particularly in rural and underserved areas (Copeland et al., 2022; Lombardi et al., 2023). This presentation will detail practical experiences and lessons learned from implementing a grant funded psychiatric CoCM pilot program in two rural FQHC settings with existing integrated behavioral health models that transitioned to an enduring billable service. Presenters will describe how federal funds supported development, implementation, and preparation to bill for services. This session is intended for leaders at FQHC organizations, academic-community partnerships, evaluators, and researchers.
