Codes and Frequencies
For sample adults aged 40 and older who have ever had a colonoscopy or had both a colonoscopy and sigmoidoscopy (COLSIGEV), COLPAY reports how much the person paid out of pocket for their most recent colonoscopy: none, part, or all of the cost.
For more information about colonoscopy variables, please refer to COLEV.
Prior to 2019, there are no comparability issues. The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
