International Classification of Diseases, 10th Revision, Clinical Modification (ICD–10–CM) codes O00–O9A are excluded from this category and included in maternal and reproductive health-related visits.

Estimates for women only.

NOTES: Percentages are based on a sample of 3,807,097 visits by adults to 58 health centers, representing an estimated 88.6 million adult visits (weighted) to health centers in all 50 U.S. states and the District of Columbia. Health centers at which all diagnoses were missing for all visits (n = 6) were excluded, and visit weights for the remaining health centers were normalized to account for excluded ones. Health center visits were categorized into diagnosis chapters using the ICD–10–CM codes that were recorded in electronic health records. Visits can be represented in multiple diagnosis chapters. More than one type of visit can be reported per visit. Sex was missing for 0.1% of the visits by adults, and missing values were excluded from the subgroup analysis by sex.
