Source of Payment Typology

The Source of Payment Typology is a payer type standard that provides a mechanism for consistent reporting of payer data to public health agencies for health care services and research. The Source of Payment Typology also provides a standard for use by those collecting data or analyzing health care information. It was created by the former PHDSC Payer Typology Subcommittee and is now hosted by the National Association of Health Data Organizations (NAHDO). NAHDO coordinates the distribution, annual review, and update of the typology.

The audience for Source of Payment Typology includes researchers, public health advocates, and healthcare analysts.
