CPT code 99291 is billed for?

• A. Basic outpatient visit
• B. Critical Care, first 30-74 minutes
• C. Discharge day management
• D. Additional 30 minutes

Answer: (B)

Understanding time-based billing for critical care E/M services is key. CPT 99291 is used for critical care when evaluating and managing a critically ill patient during the initial period, specifically up to 74 minutes. It captures the time spent providing direct critical care, rather than a standard outpatient visit. If the encounter extends beyond those initial minutes, additional time is billed with CPT 99292 for each extra 30-minute increment.

Why this fits best: the code describes the first block of critical care time (the initial period), which is exactly what 99291 covers. The other options don’t represent this scenario: a basic outpatient visit is not a critical care service; discharge day management refers to handing off or discharging a patient from an inpatient setting; and the “additional 30 minutes” piece corresponds to 99292, not the initial 74-minute block.
