Cardiac Arrhythmias VA Disability Rating: DC 7010, 7011, and 7015 Criteria

Diagnostic Code 7010 covers supraventricular arrhythmias, including paroxysmal supraventricular tachycardia (PSVT), atrial flutter, and atrial fibrillation. The rating structure focuses on the frequency of episodes requiring clinical intervention. A 30% rating is awarded when the veteran experiences five or more documented episodes per year requiring medical treatment (such as intravenous adenosine, electrical cardioversion, or acute emergency intervention). A 10% rating is assigned for one to four episodes per year requiring medical treatment, or when continuous medication is required for control, or when vagal maneuvers are required for termination.

Ventricular arrhythmias represent potentially life-threatening electrical disruptions of the heart chambers and are evaluated under DC 7011. For sustained ventricular arrhythmias or for ventricular aneurysmectomy, the schedule assigns a 100% disability evaluation for an indefinite period from the date of hospital admission. Six months following hospital discharge, a mandatory VA examination is performed and the condition is rated under the General Rating Formula for Diseases of the Heart. Implantation of an automatic implantable cardioverter-defibrillator (AICD) for sustained ventricular tachycardia or ventricular fibrillation is evaluated under DC 7011 and receives a 100% rating. For non-sustained ventricular arrhythmias without an AICD, the condition is evaluated under the General Rating Formula.

Atrioventricular block involves delayed or blocked electrical conduction between the atria and ventricles. Under DC 7015, benign conduction blocks (such as first-degree AV block or asymptomatic Mobitz Type I second-degree block) are rated under the General Rating Formula based on functional workload capacity or continuous medication. If high-grade heart block (such as Mobitz Type II or complete third-degree AV block) necessitates surgical pacemaker implantation, evaluation shifts to DC 7018 (providing 100% for one month following hospital discharge for implantation or re-implantation, with a 10% statutory minimum floor thereafter).

An essential rating rule governing heart rhythm disorders is 38 CFR 4.104 Note (1). Under this note, multiple cardiac arrhythmias (such as coexisting atrial fibrillation under DC 7010 and ventricular tachycardia under DC 7011) cannot be separately evaluated and combined under 38 CFR 4.25. Instead, adjudicators are directed to assign a single evaluation under the diagnostic code that produces the predominant disability picture.

Supporting an arrhythmia claim requires objective electrophysiological evidence. Critical documents include 12-lead electrocardiograms (ECGs) capturing the arrhythmia, 24-hour or 48-hour Holter monitor reports, 30-day cardiac event monitor logs, emergency room encounter notes showing intravenous intervention or cardioversion, electrophysiology study (EPS) reports, and the VA Heart Conditions Disability Benefits Questionnaire.
