If the cardiac arrest is due to “other” underlying condition (I46.8), the code first note is for the underlying condition, and we still have a code (I46.9) cardiac arrest, cause unspecified.
If cardiac arrest is the principal diagnosis with the ventricular tachycardia as a secondary diagnosis, the codes map to DRG 298 with a relative weight of 0.4395. If the ventricular tachycardia is the principal diagnosis and the cardiac arrest is a secondary diagnosis, it maps to DRG 310 with a relative weight of 0.5627.
Ventricular fibrillation is the most commonly identified arrhythmia in cardiac arrest patients. While there is some activity, the lay person is usually unable to detect it by palpating (feeling) the major pulse points of the carotid and femoral arteries. Such an arrhythmia is only confirmed by electrocardiography.
DRG Group #308-310 - Cardiac arrhythmia and conduction disorders without CC or MCC. DRG Group #793 - Full term neonate with major problems. The ICD-10-CM Alphabetical Index links the below-listed medical terms to the ICD code I49.01.
Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. It is due to disorganized electrical activity. Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. This is followed by death in the absence of treatment.
Ventricular fibrillation is a form of heart rhythm disturbance (dysrhythmia) that causes cardiac arrest. 2 During ventricular fibrillation, the heart stops beating normally and simply begins quivering uncontrollably. No blood is pushed through because there is no squeezing action.
V codes, described in the ICD-9-CM chapter "Supplementary Classification of Factors Influencing Health Status and Contact with Health Services," are designed for occasions when circumstances other than a disease or injury result in an encounter or are recorded by providers as problems or factors that influence care.
Atrial fibrillation occurs in the heart's upper two chambers, also known as the atria. Ventricular fibrillation occurs in the heart's lower two chambers, known as the ventricles.
Ventricular fibrillation is a type of abnormal heart rhythm (arrhythmia). During ventricular fibrillation, disorganized heart signals cause the lower heart chambers (ventricles) to twitch (quiver) uselessly. As a result, the heart doesn't pump blood to the rest of the body.
Can V codes be used as a primary diagnosis? Yes, unless otherwise specified in the code descriptor, V codes may be used as the primary diagnosis.
ICD-10 code Z03. 89 for Encounter for observation for other suspected diseases and conditions ruled out is a medical classification as listed by WHO under the range - Factors influencing health status and contact with health services .
V codes correspond with descriptive, generic, preventive, ancillary, or required medical services and should be billed accordingly.
