While men were most likely to be in the middle age groups (40-59 years), women were younger with a higher distribution in age groups 20-29 and 30-39 years.

Note that people age 65 and older may have switched from Medicaid to Medicare or have had both insurance plans. For dually-enrolled patients Medicare pays for most health care services and Medicaid pays for long-term care and home health care services.
Chart Explanation: The chart shows on the y-axis (vertical line) the percentage of patients, and the x-axis (horizontal line) shows age groups by year, gender, or race/ethnicity.
Data are from the Medicaid datasets of claims (inpatient and outpatient) for Michigan residents from 2007 to 2012. See below for the list of ICD-9-CM or ICD-10-CM diagnostic codes used to determine CKD.

Diagnoses for medical conditions within Medicaid data come from inpatient and outpatient claims submitted by providers for the fee-for-service sections of Medicaid. Only patients aged 20 and older with >3 months Medicaid eligibility were included for the analysis.
