In insurer processes, what distinguishes medical review from medical necessity determinations?

• A. Medical review assesses clinical appropriateness; medical necessity determines whether services are reasonable and necessary under plans.
• B. Medical necessity assesses clinical appropriateness; medical review determines whether services are reasonable and necessary under plans.
• C. Medical review is optional for most plans.
• D. Medical necessity is optional and not related to plan benefits.

Answer: (A)

The main idea here is distinguishing two parts of insurer review: clinical evaluation vs coverage decision. Medical review looks at whether the proposed care is clinically appropriate, based on evidence, guidelines, safety, and medical standards. It asks if the treatment makes sense for the patient’s condition from a medical standpoint. Medical necessity determinations, on the other hand, decide whether that care is covered under the specific plan. That means evaluating if the service is reasonable and necessary within the plan’s benefit design and coverage criteria.

So the best statement is that medical review assesses clinical appropriateness, while medical necessity determines whether services are reasonable and necessary under plans. The other options misstate the relationship (for example, suggesting medical review is optional or that medical necessity isn’t related to plan benefits).
