In simple words: This code indicates that the patient has both heart disease and kidney disease caused by high blood pressure.

Hypertensive heart and chronic kidney disease encompasses conditions where a patient experiences both heart disease due to hypertension and chronic kidney disease.It includes conditions specified in I11 (hypertensive heart disease) with any condition in I12 (hypertensive chronic kidney disease).

Example 1: A patient with long-standing hypertension presents with shortness of breath and fatigue.Echocardiography reveals left ventricular hypertrophy, and lab work shows elevated creatinine and decreased GFR, indicative of chronic kidney disease., A patient with a history of uncontrolled high blood pressure experiences chest pain and is diagnosed with hypertensive heart disease. Subsequent testing reveals reduced kidney function, qualifying for chronic kidney disease staging., A patient with hypertension develops both hypertensive heart disease and chronic kidney disease.While the chronic kidney disease is the primary reason for the visit, the I13 code is still applicable.

Documentation should include evidence of both hypertensive heart disease (e.g., left ventricular hypertrophy, diastolic dysfunction) and chronic kidney disease (e.g., elevated creatinine, decreased GFR, proteinuria).The stage of chronic kidney disease should also be documented and coded with the appropriate N18 code.

** For accurate and comprehensive coding, it is crucial to consult the complete ICD-10-CM coding guidelines and refer to updated coding manuals.
