For more than a year, CAFP has been an active participant in monthly Healthcare Payment Data Review Committee meetings, seeking to shape the recommendations it will present to the Legislature on how to implement a statewide All Payer Claims Database (APCD). The APCD, when fully implemented, has the potential to be an essential tool to advance our efforts to measure California health plan spending on primary care services and support. In fact, CAFP presented primary care spending measurement as a potential “use case” for the APCD, and staff for the Committee presented a similar argument for why this type of measurement could be a good first use of the database. The Committee will soon make its recommendations public, and will release its report this summer. Enacting legislation will soon follow, and CAFP will be heavily involved to ensure the law that creates the APCD reflects the progress we made with the committee.
