Experts: Make sure physician knows what to count toward 99291. Wrong: What's Critical Care? For coding purposes, a patient must be critically ill or injured in order to report critical care services. "Critically ill or injured patients have one or more vital organ systems acutely impaired, such that there is a high probability of imminent or lifethreatening deterioration in the patient's condition" if the physician does not intervene, explains Deb Williams, CPC, coding supervisor at Horizon Billing Specialists in Grand Rapids, Mich. In short: Who's Eligible for Critical Care? Some examples of patient conditions that might warrant critical care include, according to Williams: • severe allergic reactions • sepsis • impending respiratory failure • motor vehicle accident (MVA) patients with multiple injuries • myocardial infarction (MI) • alerted mental status. However: What's Included in Critical Care Time? Several other services the physician provides to the critically ill or injured patient count toward critical care time and are not separately reportable; these services commonly include: • interpretation of cardiac output measurements • chest x-rays • pulse oximetry • blood gasses • tests that store information digitally (for instance, blood pressures, hematologic data) • gastric intubation • temporary transcutaneous pacing • ventilatory management • vascular access procedures (not including most of the central line codes). Physician knowledge of this coding intricacy is not a given, explains Jim Strafford CEDC, MCS-P, vice president of client services with Omega Healthcare."A major issue with critical care is a lack of understanding on the part of ED docs as to what elements can get them to 30 minutes of critical care. I spoke with an ED physician yesterday who totally misunderstood time documentation requirements for critical care," he says. Payout: Conversely, 99285 (Emergency department visit for the evaluation and management of a patient, which requires these 3 key components within the constraints imposed by the urgency of the patient's clinical condition and/or mental status: a comprehensive history; a comprehensive examination; and medical decision making of high complexity ...) pays about $170 (4.74 RVUs multiplied by 36.0846). So be sure that you know what types of physician actions you can include in critical care time -- and what you cannot. What's Excluded from Critical Care Time? When totaling critical care minutes, you will need to deduct the time spent performing separately reportable procedures from overall critical care time, including: • CPR • endotrachael intubation • chest tube/central line insertion • ultrasound interpretation • laceration/orthopedic repairs. You should also deduct teaching time from critical care. Plus, you can't include time spent speaking with people other than the patient that does not directly bear on the patient's medical care.
