Final answer:
When 'See' follows a main term in ICD coding, it means one must look up the term that follows 'See' for additional information and the correct diagnostic code.
Step-by-step explanation:
When a medical coder or any professional working with the International Classification of Diseases (ICD) codes sees the term 'See' after a main term in the ICD manual, it implies that C) you must look up the term that follows the word. This is because 'See' is an instructional note indicating that additional information can be found under another term that will provide the correct code. For example, when a patient seeks treatment for a medical condition, physicians and other healthcare providers use ICD codes to document diagnoses, and these codes are later used for various purposes such as ordering appropriate laboratory tests, billing insurance companies, and conducting health statistics analyses.
