Between 2007 and 2012, the overall unadjusted percentage of patients with a CKD diagnosis code (ICD-9-CM or ICD-10-CM, excluding ESRD) increased slightly from 2.6% to 3.5%.
Chart Explanation: The prevalence of diagnosed CKD increased little from 2007 to 2012. The y-axis (vertical line) shows the percentage of CKD, and the x-axis (horizontal line) shows CKD groups by year (No CKD, CKD but not ESRD).
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 20 years old and above with >3 months eligibility of Medicaid were included for the analysis.

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.

Health Care System DataYes.
Regional or National?Regional—Michigan State.
Demographic GroupPatients enrolled in Medicaid in Michigan.
NumeratorPatients in denominator with diagnosed CKD from an outpatient and inpatient claim by any of the ICD-9-CM or ICD-10-CM CKD codes listed below.

Primary Data Source IndicatorDiagnosis codes from inpatient and outpatient claims.
Primary Indicator Method of MeasurementMedical claims.
Secondary (1) VariableAge at the end of the previous calendar year.
Secondary (2) VariableRace/ethnicity
Secondary (3) VariableSex/gender
Secondary (4) VariableDiabetes status determined by the presence of an ICD-9-CM code (250.x, 357.2, 362.01, 362.02 or 366.41) or ICD-10-CM code (E08.3xx, E08.4xx, E09.3xx, E09.4xx, E10.xxx,  E11.xxx, E13.0x, E13.1x, E13.2x, E13.3xx, E13.4x, E13.5x, E13.6xx, E13.8, E13.9) for diabetes or diabetic complications on at least one inpatient or outpatient claim during the given calendar year.
Secondary (5) VariableHypertension status determined by the presence of an ICD-9-CM code (401.x through 405.x) or ICD-10 code (H35.03x, I10.xx, I11.xx, I12.xx, I13.xx, I15.xxx, I67.4, N26.2) for hypertension on at least one inpatient or outpatient claim during the given calendar year.
Period Currently Available2007–2012.
Limitations of IndicatorAs a measure of prevalence, the use of ICD-9-CM or ICD-10-CM diagnostic codes will underestimate the level of CKD in the general population.
Analytical ConsiderationsIn the published literature, CKD is diagnosed by ICD-9-CM or ICD-10-CM codes in different ways (e.g., one outpatient code, two or more outpatient codes, or one inpatient code). In addition to these differences in ascertaining CKD, there may be differences in sampling. Thus, care must be taken when making comparisons.
