This micro-data file contains data collected in the 2015 National Ambulatory Medical Care Survey (NAMCS).  
NAMCS is a national probability sample survey conducted by the Division of Health Care Statistics, National 
Center for Health Statistics (NCHS).  For 2015, the sampling design allowed for the estimation of ambulatory 
medical care visits to office-based physicians and community health centers (CHCs) in 16 states and 4
additional groups formed by aggregating the remaining states within their Census regions. 

The data can be weighted to produce national estimates that describe the utilization of ambulatory medical care 
services in the US.  Only visits to office-based physicians are included in this data file.  
Visits to CHCs are not included. A separate file containing CHC visits to both physicians and 
non-physician practitioners (physician assistants, nurse practioners, and nurse mid-wives) is planned for a future release.
