The National Ambulatory Medical Care Survey (NAMCS) Health Center Component, conducted by the National Center for Health Statistics (NCHS), collects annual data on visits to health centers to describe patterns of utilization and provision of ambulatory care delivery in the United States. Data are collected from federally qualified health centers (FQHCs) and FQHC look-alikes from all 50 U.S. states and the District of Columbia and are used to develop nationally representative estimates.
The data include preliminary, biannual counts and rates of health center visits from January 2022-December 2024 by medical diagnosis chapters, maternal and reproductive health-related diagnoses, mental health disorders, and respiratory conditions, stratified by selected patient characteristics. Estimates are split into biannual time periods (January to June, and July to December) and are considered preliminary, meaning they may differ from final estimates.
