AHIMA Documentation Integrity Practitioner (CDI) CDIP Question # 25 Topic 3 Discussion

This response provides the highest level of specificity for the patient’s diagnosis because it includes the following elements:

The type of heart failure: diastolic, which means the heart has difficulty relaxing and filling with blood during diastole, resulting in increased filling pressures and pulmonary congestion. Diastolic heart failure is also known as heart failure with preserved ejection fraction (HFpEF), which is defined as an ejection fraction of 50% or higher 2.

The acuity of heart failure: acute on chronic, which means the patient has a history of chronic heart failure that has worsened acutely due to a precipitating factor, such as infection, ischemia, arrhythmia, or medication noncompliance. Acute on chronic heart failure is associated with higher mortality and morbidity than stable chronic heart failure 3.

The associated conditions: hypertensive renal disease and CKD 3, which indicate that the patient has kidney damage and reduced kidney function due to high blood pressure. CKD 3 is the third stage of chronic kidney disease, which is characterized by a glomerular filtration rate of 30 to 59 mL per minute per 1.73 m2 4.

The other responses are less specific because they either omit or misrepresent some of these elements. For example, response B incorrectly states that the patient has systolic heart failure, which is contradicted by the echocardiogram result. Response C does not specify whether the heart failure is chronic or acute on chronic, which has implications for treatment and prognosis. Response D does not specify the type of heart failure, which affects the coding and classification of the condition.
