I13.0Hypertensive heart and chronic kidney disease with heart failure and stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease

I13.0 is the ICD-10-CM diagnosis code for hypertensive heart and chronic kidney disease with heart failure and stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease. It belongs to category I13 (hypertensive heart and chronic kidney disease), block I10-I1A (hypertensive diseases) and chapter 9 (diseases of the circulatory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within I13, choose I13.0 (with heart failure and stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease) only when documentation doesn't support a more specific option: without heart failure (I13.1) and with heart failure and with stage 5 chronic kidney disease, or end stage renal disease (I13.2).

Use an additional code to identify type of heart failure (I50.-). Use an additional code to identify stage of chronic kidney disease (N18.1-N18.4, N18.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 291 (Heart Failure and Shock with MCC, relative weight 1.2685), DRG 292 (Heart Failure and Shock with CC, relative weight 0.8616), DRG 293 (Heart Failure and Shock without CC/MCC, relative weight 0.5462), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 05 (Diseases and Disorders of the Circulatory System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 404.01 (hypertensive heart and chronic kidney disease, malignant, with heart failure and with chronic kidney disease stage I through stage IV, or unspecified), 404.11 (hypertensive heart and chronic kidney disease, benign, with heart failure and with chronic kidney disease stage I through stage IV, or unspecified) and 404.91 (hypertensive heart and chronic kidney disease, unspecified, with heart failure and with chronic kidney disease stage I through stage IV, or unspecified).
