Final answer:
The ICD-10-CM's Index to External Causes is used by healthcare professionals to code and classify external causes of injury and other health-related incidents for clinical documentation and billing. It can be found in medical records and on death certificates.
Step-by-step explanation:
The Index to External Causes is a component of the International Classification of Diseases (ICD-10-CM), which is a coding system developed by the World Health Organization (WHO) used worldwide. This index helps health professionals code and classify external causes of injury, poisoning, and other adverse reactions that affect a person's health status. For example, when a patient seeks treatment for injuries sustained in a car accident, medical professionals use the ICD-10-CM codes to document the external cause of the injury.
These codes are essential for clinical documentation, health statistics, and billing purposes. Two primary locations where you would likely find an ICD code include medical records within healthcare facilities and on death certificates maintained by vital-records keepers. Moreover, these codes are crucial for medical billers and coders in processing insurance claims, for epidemiologists analyzing morbidity and mortality statistics, and for other relevant health-care management systems.
