Understanding Left Ventricular Diastolic Dysfunction LVDD diagnosis coding and documentation is crucial for accurate healthcare reimbursement. This guide covers LVDD symptoms, ICD-10 codes I43 and I50.30, diastolic heart failure treatment, ejection fraction preservation, and clinical documentation improvement CDI best practices for physicians and medical coders. Learn about the difference between diastolic and systolic heart failure, LVDD grades and stages, and relevant medical terminology for optimal clinical care and accurate billing.
Also known as
Diastolic heart failure
Heart's left ventricle has trouble relaxing and filling with blood.
Other heart failure
Unspecified heart failure, including cases not fitting other I50 categories.
Hypertensive heart disease w heart failure
Heart failure caused by high blood pressure, sometimes with diastolic dysfunction.
Cardiomyopathy
Diseases of the heart muscle, some types can cause diastolic dysfunction.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is LV diastolic dysfunction due to underlying heart disease?
Yes
Specify underlying heart disease.
No
Is it isolated or unspecified?

Coding I43.8, Heart failure, unspecified, without specifying diastolic dysfunction, undercodes severity and impacts reimbursement.
Failing to code associated conditions like hypertension (I10) or diabetes (E11) with diastolic dysfunction impacts risk adjustment.
Lack of documentation specifying grade or stage of left ventricular diastolic dysfunction (I51.81 with appropriate 4th digit) leads to coding errors and claim denials.
Patient presents with complaints suggestive of left ventricular diastolic dysfunction (LVDD). Symptoms include dyspnea on exertion, orthopnea, paroxysmal nocturnal dyspnea, and fatigue. Physical examination reveals bibasilar crackles, an S4 heart sound, and jugular venous distention. The patient's medical history includes hypertension, diabetes mellitus, and obesity, all known risk factors for diastolic heart failure. Echocardiography demonstrates preserved left ventricular ejection fraction (LVEF) with evidence of impaired left ventricular relaxation, including elevated E/e' ratio and prolonged isovolumic relaxation time. Diastolic dysfunction grade (grade I, II, or III) is specified based on echocardiographic findings. Differential diagnoses considered include systolic heart failure, valvular heart disease, and constrictive pericarditis. A diagnosis of left ventricular diastolic dysfunction is made based on the constellation of symptoms, physical exam findings, and echocardiographic results. Treatment plan includes optimal management of underlying comorbidities, such as hypertension and diabetes, with emphasis on lifestyle modifications including sodium restriction and regular exercise. Pharmacological therapy may include diuretics for symptom relief and beta-blockers or calcium channel blockers for heart rate control. Patient education focuses on medication adherence, symptom monitoring, and the importance of follow-up appointments for ongoing assessment of cardiac function and adjustment of therapy as needed. ICD-10 code I51.83, diastolic heart failure, is assigned. CPT codes for echocardiography and other diagnostic tests performed are documented.
