Final answer:
In ICD-9 coding, new entries are indicated by a bold print or a bullet. ICD codes are found in medical laboratories for testing and on health insurance claims for reimbursement processes.
Step-by-step explanation:
The symbols used in ICD-9 coding to indicate a new entry are typically a bold print or a bullet (•). When it comes to medical coding and billing, ICD codes play a crucial role in the healthcare process. For example, clinicians use ICD codes to order laboratory tests and prescribe treatments, laboratories use them to identify necessary tests, health-care management systems to verify treatments, coders assign them for procedures performed, billers process claims for insurance reimbursement, vital-records keepers to record causes of death, and epidemiologists calculate statistics.
Two locations where one would likely find an ICD code include medical laboratories, where the codes identify the tests to be performed based on a patient's diagnosis, and on health insurance claims, where the codes are used to process and validate the treatments covered for reimbursement.
