Critical Care Charting & Charging: Documenting for Accuracy and Compliance (Live)-Handout

Handout - Critical Care Charting

Pdf Summary

The presentation reviewed professional and facility billing for critical care (CC), including documentation, time calculations, concurrent services, procedures, and trauma team activation fees.<br /><br />Critical care requires both a critically ill or injured patient—at high risk of life-threatening deterioration—and services involving high-complexity decision-making to support vital organ systems or prevent further decline. A patient’s severity alone does not make an encounter billable as CC. Documentation should establish the critical nature of the condition, medical necessity, high-complexity care, and total qualifying time. Time may include direct care and related documentation while the provider remains immediately available, but excludes separately billed procedures, travel, care of other patients, and other nonqualifying activities.<br /><br />CPT 99291 covers the initial CC interval; 99292 applies to additional time. Under Medicare rules effective in 2023, 99292 requires 104 total minutes. Separately reportable procedures should not be counted toward CC time. Different specialties may bill on the same date when their services are medically necessary and nonduplicative. For the same physician or group, combine time and bill 99291 only once per day. Split/shared physician and nonphysician practitioner services require nonoverlapping time and modifier FS; since 2024, the clinician with the most time bills the service.<br /><br />Facility CC billing differs from professional billing and may draw on documented professional and nursing time without double counting, subject to hospital guidelines. Documentation should clearly support severity and care provided.<br /><br />The session also addressed trauma activation fees. Medicare requirements include pre-arrival notification, activation under established criteria before arrival, treatment by the qualified trauma team, and medically necessary care. A September 2025 OIG audit found widespread compliance concerns, especially missing notification or inappropriate or late activation. Recommended safeguards include clear activation criteria, accurate timestamps, documented medical necessity, and ongoing compliance monitoring.
