The population aged 20 to 64 years is primarily white for the years analyzed for patients enrolled in commercial insurance from Optum Clinformatics.

 
Chart Explanation: The chart shows on the y-axis (vertical line) the percentage of patients, and the x-axis (horizontal line) shows the age groups by year, gender, or race/ethnicity.
The Clinformatics Commercial™ dataset provides paid medical and prescription claims and enrollment information for participants in commercial insurance plans.

CKD is defined using ICD-9-CM or ICD-10-CM diagnosis codes, and ESRD is based on ICD diagnosis, CPT procedure, and DRG codes in the Clinformatics Commercial.

Limitations of IndicatorThe use of an ICD-9-CM or ICD-10-CM diagnosis code as a measure of prevalence, will underestimate the level of diabetes or hypertension in the general population.
Analytical ConsiderationsIn published literature, CKD is diagnosed by ICD-9-CM or ICD-10-CM codes in alternate ways (one outpatient, two or more outpatient or one inpatient claim). Care must be taken in comparisons.
