i22

i22 refers to a classification code used in the International Classification of Diseases, Tenth Revision (ICD-10). Specifically, it falls under the category of diseases of the circulatory system. Within this broad category, i22 denotes myocardial infarction, also commonly known as a heart attack.

The ICD-10 system is a medical classification list by the World Health Organization (WHO). It is used by physicians and other healthcare providers to classify and code all diagnoses, symptoms, and procedures recorded in conjunction with hospital care. The i22 code is further broken down into subcategories to specify the type and location of the myocardial infarction, such as i22.0 for myocardial infarction of anterior wall, i22.1 for myocardial infarction of inferior wall, and i22.9 for unspecified myocardial infarction.

Accurate coding using classifications like ICD-10 is crucial for various reasons, including statistical analysis of disease prevalence, epidemiological studies, health services research, and administrative purposes such as billing and reimbursement. The i22 code, therefore, plays a significant role in the global health data infrastructure by providing a standardized way to record and report instances of heart attacks.
