A patient presented with shortness of breath, elevated B-type natriuretic peptide, and lower extremity edema to the emergency room. During the hospitalization, a cardiac echocardiogram was performed and revealed an ejection fraction of 55% with diastolic dysfunction. The patient's history includes hypertension (HTN), chronic kidney disease (CKD) (baseline glomerular filtration rate 40) and congestive heart failure (CHF). The clinical documentation integrity practitioner (CDIP) has queried the physician to further clarify the patient’s diagnosis. Which response provides the highest level of specificity?
