Practice Billing for Medicare Advance Care Planning Across the USA.

Several years after Medicare introduced ACP reimbursements for physicians, relatively few practices bill for ACP. ACP billing was more likely in large practices with a greater percentage of primary care physicians. To increase ACP billing uptake, policymakers and health system leaders might target interventions to larger practices where a small number of physicians already bill for ACP and to specialty practices that serve as the primary source of care for seriously ill patients.
