Overview

Critical Care —
Direct delivery of medical care for critically ill or critically injured patients who are acutely at risk of life-threatening organ dysfunction.

Key Points

➔ Focuses on high-acuity, complex care requires constant attention and decisionmaking.

➔ Usually involves high-risk interventions and intensive monitoring.

➔ Can occur in ED, ICU, or other inpatient settings.

Covering CPT Codes
99291: Critical care, first 30–74 minutes on a given date
99292: Each additional 30 minutes of critical care

Documentation Essentials

Documentation Checklist

Critical care documentation should include:

Patient Identification & Location – ICU, ED, or other acute care unit

Reason for Critical Care – Explicit statement of life-threatening condition or organ dysfunction

HPI / Pertinent History – Relevant history contributing to acute illness

Assessment of Severity / Organ Systems:

    • Vital signs
    • Labs
    • Imaging
    • Hemodynamic status
    • Organ support

Interventions / Procedures:

    • Airway management
    • mechanical ventilation
    • vasoactive meds
    • invasive monitoring
    • dialysis, etc.

Time Documentation:

    • Total time spent providing critical care (direct patient care)
    • Note start and end times for all sessions

 MDM / Risk:

  • High complexity, immediate life-threatening conditions
  • Include rationale for interventions and management decisions
Example Correct Time-Based Note

Total critical care time 95 minutes:
– Initial 30 min for airway management and resuscitation (99291),
– plus 65 min continued monitoring,titrating vasoactive medications, and coordinating care with ICU team (99292, 2 units).

CDI & Audit Considerations

1. Document the organ system involved and life-threatening conditions.

2. Include all critical interventions.

3. Record accurately all physician/qualified provider time.

4. Avoid counting routine bedside monitoring/non-critical interventions.

5. Ensure that documentation supports time-based code selection

6. Ensure accurate use of precise terminology to support 99291 vs 99292 units

Common Audit Triggers

  1. Lack of time documentation
  2. Lack of clarity regarding critical/non-critical interventions
  3. Lack of clarity regarding organ system failure
  4. Concurrent billing of non-critical E/M code for the same condition
