ICD-10-CM Coding: Hypertensive Heart Disease, Chronic Kidney Disease, and Hypertension

ICD-10-CM Coding: Hypertensive Heart Disease, Chronic Kidney Disease, and Hypertension

Hypertensive heart disease refers to a group of disorders that includes heart failure, ischemic heart disease, and left ventricular hypertrophy. It is the number one cause of death associated with high blood pressure. Documentation must state (heart failure due to hypertension) or imply a causal relationship (hypertensive heart failure) to assign a code from category I11, Hypertensive heart disease.

Guidelines state that there is a presumptive cause-and-effect relationship between hypertension and chronic kidney disease.

If a patient has all three conditions present—hypertension, heart disease, and chronic kidney disease—the guidelines state that the connection must be made for the heart disease and hypertension, but not for the CKD and hypertension.

EXAMPLE 1:

Assessment: 1. Hypertension 2. Chronic diastolic congestive heart failure.

I10 Essential (primary) hypertension

I50.32 Chronic diastolic (congestive) heart failure

Becuase there is no causal relationship indicated, the two conditions are coded separately.

EXAMPLE 2:

Assessment: Hypertension with hypertensive chronic diastolic congestive heart failure

I11.0 Hypertensive heart disease with heart failure

I50.32 Chronic diastolic (congestive) heart failure

The causal relationship is indicated; therefore, the first-listed code is now different. The instructional note under code I11.0 states that the second code is still necessary to identify the type of heart failure.

EXAMPLE 3:

Patient is a 75-year-old female with hypertension and stage 3 CKD with a creatinine of 1.8.

I12.9 Hypertensive chronic kidney disease with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease

N18.3 Chronic kidney disease, stage 3 (moderate)

    How to code hypertension with nephropathy?

    can we code I11.9 for hypertension with CAD?

    This is not correct. Per ICD 10 CM guidelines the two conditions are linked by the term “with” in the Alphabetic Index. These conditions should be coded as related even in the absence of provider documentation explicitly linking them. Unless documentation clearly states the conditions are unrelated. Which means the first example provided is wrong- We assume there is a causal relationship.

    As for CAD there is no “with” (besides angina) that would indicate this.

    The ICD 10 guidelines state conditions classified to I50.x and I51.4-I51.9, which does not include CAD.
