•Causes of heart failureoCoronary artery disease, cardiomyopathy, hypertension or heart valve diseaseoCan affect the heart’s left side, right side or both•Effects of heart failureoFluid in the lungs, kidney function hampered, blood does not circulate properly so fluid collects in tissues•Left sided or left ventricular heart failure makes the left side of the heart work harder to pump the same amount of blood•Two types of left-sided heart failureoSystolic failure: left ventricle loses its ability to contract normallyoDiastolic failure: left ventricle loses its ability to relax normally•Right sided heart failure occurs as the result of left sided heart failure. The right side loses pumping power and blood backs up in the body’s veins and causes swelling in the legs and ankles.•Congestive heart failure causes blood to flow out of the heart at a slower rate and blood in the veins trying to return to the heart will slow down and congestion in the body tissues occurs. The patient has pulmonary and systemic congestion.Cardiac Arrhythmias and Conduction Disorders•Cardiac arrhythmias and conduction disorders identify disturbances or impairment of the normal electrical activity of the heart muscle excitation.•Types include:oAtrial fibrillation and atrial flutteroVentricular fibrillation and paroxysmal tachycardiaoSick sinus syndrome and Wolf-Parkinson-White syndromeoAtrioventricular (AV) heart blocksoSupraventricular tachycardia4
Chapter 12: Diseases of the Circulatory System (I00–I99)Cardiac Arrest•ICD-10-CM has three codes for cardiac arrestoCardiac arrest due to underlying cardiac conditionoCardiac arrest due to other underlying condition•Both codes have a “code first” note to code the underlying conditionoCardiac arrest, cause unspecified•Cardiac arrest codes exist in other ICD-10-CM chapters for when it occurs with abortion, ina newborn, complicating anesthesia, complicating delivery and during or after a procedure.•Cerebrovascular Disease•Cerebrovascular disease are a variety of conditions.•Specific codes exist for various forms of cerebrovascular accidents (CVAs) oCerebral hemorrhage or infarction due to a thrombosis, embolism or unspecified occlusion or stenosis in the cerebral vesseloCerebral infarction codes identify the specific cerebral artery involved and laterality (right or left side)•Category I69, Sequelae of cerebrovascular disease, contains codes for very specific conditions that remain after the acute CVA is treated.•Late effects of cerebrovascular disease are differentiated by the type of stroke (hemorrhage or infarction.)•Carotid artery stenosisoOcclusion and stenosis of precerebral arteries include the carotid artery and may be unilateral or bilateral. Patients may or may not have a stroke as a result.
