Still to date this model of care emphasizes team-based comprehensive, continuous and coordinated care. The care model is intended to improve primary care generally via improved patient communication, care quality, safety and outcomes. In several ways the ACA encouraged the adoption of the, now termed, Primary Care Medical Home/PCMH for both the Medicaid and Medicare programs and among private health insurers. (In some ways the PCMH is seen as a precursor for providers interested in becoming an Affordable Care Organization (ACO), i.e., taking on reimbursement risk.) Over the past few years PCMHs have become widely adopted. Over forty state Medicaid programs are experimenting with the model along with 90 commercial health plans and three federal initiatives.
