Y52.1: Calcium-channel blockers

Calcium-channel blockers are a type of medication that is often administered for the treatment of various cardiovascular conditions such as hypertension (high blood pressure), angina pectoris (chest pain), and certain types of arrhythmias (irregular heart rhythms). They work by preventing calcium from entering cells of the heart and arteries. The ICD-10 code Y52.1 doesn't point to a disease or condition, but rather serves as a categorization for undesired side effects or complications which can occur due to the use of these medications. Side effects can range from minor instances, like feeling dizzy or flushing, to more severe conditions such as heart failure or a major drop in blood pressure. This code is used in medical coding systems to keep track of these cases and to work on minimizing such occurrences. The progression and specifics of these complications can vary greatly on an individual basis based on factors like the patient's health status, age, and the specific type and dosage of the calcium-channel blocker used.
