  • 2015
  • Billable Thru Sept 30/2015
  • Non-Billable On/After Oct 1/2015

  • ICD-9-CM 428.9 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 428.9 should only be used for claims with a date of service on or before September 30, 2015. For claims with a date of service on or after October 1, 2015, use an equivalent ICD-10-CM code (or codes).

Clinical Information
  • A disorder characterized by the inability of the heart to pump blood at an adequate volume to meet tissue metabolic requirements, or, the ability to do so only at an elevation in the filling pressure
  • A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (ventricular dysfunction), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as myocardial infarction
  • Heart failure is a condition in which the heart can't pump enough blood throughout the body. Heart failure does not mean that your heart has stopped or is about to stop working. It means that your heart is not able to pump blood the way it should. The weakening of the heart's pumping ability causes
    • blood and fluid to back up into the lungs
    • the buildup of fluid in the feet, ankles and legs - called edema
    • tiredness and shortness of breath
    the leading causes of heart failure are coronary artery disease, high blood pressure and diabetes.treatment includes treating the underlying cause of your heart failure, medicines, and heart transplantation if other treatments fail.heart failure is a serious condition. About 5 million people in the United States Have heart failure. It contributes to 300,000 deaths each year
  • Inability of the heart to pump blood at an adequate rate to fill tissue metabolic requirements or the ability to do so only at an elevated filling pressure
  • Inability of the heart to pump blood at an adequate rate to meet tissue metabolic requirements or the ability to do so only at an elevated filling pressure
  • Inability of the heart to pump blood at an adequate rate to meet tissue metabolic requirements. Clinical symptoms of heart failure include: unusual dyspnea on light exertion, recurrent dyspnea occurring in the supine position, fluid retention or rales, jugular venous distension, pulmonary edema on physical exam, or pulmonary edema on chest x-ray presumed to be cardiac dysfunction

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 428.9 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
