Final answer:
Documentation is essential when patients receive radiologic services, as it ensures continuity of care, legal compliance, and serves as a reference for future treatment.
Step-by-step explanation:
The correct answer to the question is B. Documentation. When a patient receives diagnostic or therapeutic radiologic services, it is crucial for radiologists and radiographers to perform proper documentation. This task involves recording all relevant patient information, the details of the procedure, the results, and any follow-up care that may be necessary. Effective documentation ensures continuity of care and legal compliance, also serving as a point of reference for future treatment. It is less about authorization or coding, which have their own specific contexts within healthcare services, and while charting may be a part of documentation, the question specifically refers to the broader scope of recording detailed information.
