Which of the following management activities is used to increase revenue, reduce days in accounts...

Revenue cycle management (RCM) is the end-to-end set of administrative and financial processes that manage patient service revenue from pre-registration and eligibility through coding, billing, claims submission, payment posting, denial management, and collections . Because RCM spans the full lifecycle, it directly targets the three outcomes named in the question. First, it increases revenue by improving charge capture, ensuring accurate clinical documentation and coding, and preventing underbilling. Second, it reduces days in accounts receivable (A/R) by streamlining claim submission, improving first-pass claim acceptance, accelerating payment posting, and prioritizing follow-up on unpaid claims. Third, it reduces denied claims by strengthening front-end verification (coverage, authorization), enforcing coding and medical necessity rules, and implementing denial analytics and appeal workflows to fix root causes.

“Revenue optimization” is a broader, less standardized term that may describe strategic improvement efforts but does not specifically represent the operational discipline that controls A/R and denials across the full cycle. “Revenue accounting” focuses on financial reporting and recognition rather than operational claim performance. “Expense management” targets cost reduction, not revenue realization. Therefore, RCM is the management activity that best fits all elements of the prompt.
