This thesis argues for providing spiritual care in primary care for Massachusetts persons with disabilities having Medicare and Medicaid as their primary insurers. It outlines an advocacy strategy to (1) increase awareness of the importance of spiritual care as key to primary care, (2) get buy-in for spiritual care as an optional primary care service to Medicaid beneficiaries needing nonmedical supports and services to live in the community due to mental health diagnosis or physical disability, and (3) put forward a statutory or regulatory proposal requiring One Care plans to provide certified peer chaplains as a covered service starting 2023.
