Final answer:
ICD codes are used widely in the healthcare sector, appearing in various settings such as medical records at clinics and hospitals, and on insurance reimbursement claims.
Step-by-step explanation:
The student's question relates to the assignment of medical codes, which include both the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes for diseases and related health conditions, as well as Current Procedural Terminology (CPT) and Healthcare Common Procedure Coding System (HCPCS) codes for medical procedures and services. ICD codes are integral to the healthcare industry, as they are used by clinicians to inform treatment decisions, by medical laboratories to validate tests, by health-care management systems to ensure appropriate treatment, by medical coders to document procedures, by medical billers to process insurance claims, by vital-records keepers to record causes of death, and by epidemiologists to track disease statistics.
Two locations where you would likely find an ICD code are on a patient's medical records within a clinic or hospital and on documents submitted to insurance companies for reimbursement claims.
