Both from a clinical standpoint and according to Coding Clinic First Quarter 2016 page 10, preserved left ventricular systolic function is another term used to describe ventricular diastolic dysfunction.
Left vestibular function disorder ICD-10-CM Diagnosis Code I50.1 [convert to ICD-9-CM] Left ventricular failure, unspecified
The ICD-10 Index indicates that ventricular dysfunction without heart failure is assigned code to code I51.9 (unspecified heart disease), not code I51.89. However, I51.9 is a non-CC and a non-HCC so coding it really serves not particular useful purpose. It ought to have a specific cause which should be coded.
Failure of adequate output by the left ventricle despite an increase in distending pressure and in end-diastolic volume, with dyspnea, orthopnea, and other signs and symptoms of pulmonary congestion and edema. Heart failure involving the left ventricle.
e.g. clinical statements of 'left ventricular systolic dysfunction (LVSD)' or 'reduced ejection fraction' (where there is no stated diagnosis of failure or cardiomyopathy) would be coded as R93. 10.

INTRODUCTION Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome in which patients have signs and symptoms of HF as the result of high left ventricular (LV) filling pressure despite normal or near normal LV ejection fraction (LVEF; ≥50 percent) [1-5].
The clinical syndrome of heart failure with preserved left ventricular function (LVF) also defined as HF with a normal ejection fraction, is a common condition in patients with HF and has emerged as a serious clinical problem.
Left ventricular systolic dysfunction (LVSD) is a common and serious complication of myocardial infarction (MI) that leads to greatly increased risks of sudden death and of heart failure. Effective and cost effective treatment is available for such patients that can reduce both morbidity and mortality.
Background. Left ventricular diastolic dysfunction (DD) is defined as the inability of the ventricle to fill to a normal end-diastolic volume, both during exercise as well as at rest, while left atrial pressure does not exceed 12 mm Hg.
Heart failure with preserved ejection fraction (HFpEF) is a type of heart failure that occurs when the muscle in the left ventricle stiffens and is less able to relax, so the pressure inside the heart rises. HFpEF is usually caused by coronary artery disease, valvular heart disease, diabetes, obesity, or hypertension.
Several studies have reported that, among elderly heart failure patients, approximately 50% have preserved left ventricular systolic function. This syndrome, often referred to as diastolic heart failure, is more common in women and in persons with antecedent hypertension.1,2.
Definition. Left ventricular function measurements are used to quantify how well the left ventricle is able to pump blood through the body with each heartbeat. Left ventricular function (LVF) is an extremely important parameter in echocardiography as it can alter in several diseases.
With the recent wide availability of non-invasive assessments of left ventricular function it has become apparent that many patients diagnosed as having heart failure have preserved left ventricular systolic function.
Heart failure with preserved ejection fraction (HFpEF), also referred to as diastolic heart failure, is characterized by signs and symptoms of heart failure and a left ventricular ejection fraction (LVEF) greater than 50%.
HFpEF is preceded by chronic comorbidities, such as hypertension, type 2 diabetes mellitus (T2DM), obesity, and renal insufficiency, whereas HFrEF is often preceded by the acute or chronic loss of cardiomyocytes due to ischemia, a genetic mutation, myocarditis, or valvular disease [5,6].
