For this patient, CHF and hypertension would be coded as code I11. 0, Hypertensive heart disease with heart failure since the causal relationship is assumed due to the word “with” following the main term in the Alphabetic Index under hypertension. Since the heart disease falls within the code range of I50. - or I51.
The combination of hypertension and hypertensive heart disease is currently coded using the ICD-9 402. xx series of codes. As noted earlier, each category is currently divided into malignant, benign, and unspecified essential hypertension with or without heart failure.
Hypertensive heart disease refers to heart conditions caused by high blood pressure. The heart working under increased pressure causes some different heart disorders. Hypertensive heart disease includes heart failure, thickening of the heart muscle, coronary artery disease, and other conditions.
If hypertension, heart failure and chronic kidney disease are all documented, use a combination code from category I13 — hypertensive heart and chronic kidney disease. These are just a few examples of conditions that have an assumed causal relationship in ICD-10-CM.
Hypertensive heart disease refers to heart problems that occur because of high blood pressure that is present over a long time. Hypertension is a disorder characterized by consistently high blood pressure.
Heart failure is assumed to be due to hypertension when coded using I11. 0, “Hypertensive heart disease with heart failure.” In ICD-10, the word “with” presumes a causal relationship between the two conditions linked by this term.
Epidemiological studies have established a strong association between hypertension and CAD. Hypertension is a major independent risk factor for the development of CAD, stroke, and renal failure.
High blood pressure can lead to CAD because it adds force to the artery walls. Over time, this can damage these blood vessels and lead to more plaque buildup. The narrowed artery limits or blocks the flow of blood to the heart muscle, which means it might not get enough oxygen.
High blood pressure (BP) is one of the most important risk factors for cardiovascular disease (CVD), which is the leading cause of mortality.
Code I25* is the diagnosis code used for Chronic Ischemic Heart Disease, also known as Coronary artery disease (CAD). It is a is a group of diseases that includes: stable angina, unstable angina, myocardial infarction, and sudden coronary death.
