About I13.10

I13.10 is the ICD-10-CM diagnosis code for hypertensive heart and chronic kidney disease without heart failure, with 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 I13.1, choose I13.10 (with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease) only when documentation doesn't support a more specific option: with stage 5 chronic kidney disease, or end stage renal disease (I13.11).

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

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 682 (Renal Failure with MCC, relative weight 1.4656), DRG 683 (Renal Failure with CC, relative weight 0.8647) and DRG 684 (Renal Failure without CC/MCC, relative weight 0.6003), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), 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 404.00 (hypertensive heart and chronic kidney disease, malignant, without heart failure and with chronic kidney disease stage I through stage IV, or unspecified), 404.10 (hypertensive heart and chronic kidney disease, benign, without heart failure and with chronic kidney disease stage I through stage IV, or unspecified) and 404.90 (hypertensive heart and chronic kidney disease, unspecified, without heart failure and with chronic kidney disease stage I through stage IV, or unspecified).
