Annual total of direct health care payments from TRICARE to ambulatory chiropractors


For all persons, AMCHIEXTR captures the sum of direct payments made by TRICARE (formerly CHAMPUS) for care provided by ambulatory chiropractors during the year. Ambulatory care visits are those that involve medical provider and hospital outpatient combined visits. Refer to the comparability tab for information on how the specific sources of payment included in AMCHIEXTR change over time. Payments for over-the-counter drugs and indirect payments not related to specific medical events, such as Medicaid Disproportionate Share and Medicare Direct Medical Education subsidies, are not included in this amount.
