Hypertensive heart and chronic kidney disease (I13)

ICD-10 codes in the I13 category are specifically used to identify and classify conditions involving hypertensive heart disease combined with chronic kidney disease. These codes distinguish whether the patient has accompanying heart failure and the stage of kidney disease, making them essential for precise documentation of intertwined cardiovascular and renal complications caused by hypertension.

This section covers the spectrum of hypertensive heart and chronic kidney disease, including cases with or without heart failure, and details stages 1 through 5 of chronic kidney disease or end-stage renal disease. For example, I13.0 codes cases with heart failure and kidney disease stages 1-4 or unspecified, while I13.1 refers to those without heart failure. The code I13.11 is used when kidney disease has progressed to stage 5 or end-stage renal disease without heart failure, and I13.2 covers combined heart failure and stage 5 kidney disease. Synonyms like "hypertensive heart and renal disease," "cardiorenal syndrome," and "hypertensive renal failure" reflect common clinical terms linked to these codes. Using these codes correctly helps ensure accurate recording of complex hypertension-related heart and kidney conditions, including those complicating pregnancy or childbirth.
