Step-by-step explanation:
ICD-10-CM codes are used in the field of Medicine to indicate the reason for services performed. These codes are used by clinicians to order laboratory tests, prescribe treatments, and diagnose diseases. They are also used by medical laboratories, health-care management systems, medical coders, medical billers, vital-records keepers, and epidemiologists for various purposes in the healthcare system.
An ICD code can be found in two locations: on a patient's medical record, where it is used by healthcare professionals to document and track diagnoses; and on medical claims submitted to insurance companies for reimbursement, where it is used to justify the services provided.
