Final answer:
Grouping codes that are related to a procedure is called coding.
Step-by-step explanation:
In the context of medical coding, grouping codes that are related to a procedure, rather than billing each individual code, is called coding. This process involves assigning specific alphanumeric codes to medical procedures, diagnoses, and treatments.
