Evaluation and management
About 99291: Initial critical care service
Report 99291 when a physician or qualified health care professional spends at least 30 minutes managing a patient at high risk of imminent, life-threatening deterioration.
Critical care involves active management of an illness or injury that acutely threatens a vital organ system, with a high likelihood of imminent, life-threatening deterioration. Typical situations include septic shock requiring vasopressors and acute respiratory failure requiring ventilatory support. Emergency physicians, intensivists, hospitalists, and other physicians or qualified health care professionals furnish it in an ICU, emergency department, or another setting. The patient's condition and the care provided, not the location, establish whether the service qualifies.
Report 99291 after at least 30 minutes of qualifying critical care on the same date. Intervals need not be continuous, but overlapping practitioners' time cannot be counted twice. Document the critical condition, interventions, and total qualifying time. Count bedside care and directly related work on the unit, including necessary discussions with surrogates when the patient cannot participate. Exclude time spent on separately billable procedures, such as intubation or central venous catheter insertion. Chest radiograph and blood gas interpretation, pulse oximetry, ventilator management, gastric intubation, and peripheral vascular access are included in critical care. For Medicare, the first unit of 99292 requires 104 total minutes.

99291 billing questions
When does Medicare allow 99292 to be added to 99291?
Medicare requires at least 104 total minutes of critical care for the first unit of 99292. CPT reporting starts the add-on at 75 minutes, so the threshold differs.
Can an ED visit and critical care be billed the same day?
Medicare allows both when a medically necessary, separately identifiable ED visit occurred before the patient's condition became critical. Append modifier 25 to the ED visit and document the change in condition.
Which procedures can be billed separately with 99291?
Endotracheal intubation, CPR, central venous catheter placement, arterial line placement, and cardioversion may be separately reported when performed. Exclude the time spent on each separately reported procedure from critical care time.
How is split or shared critical care reported?
When a physician and an NP or PA in the same group furnish critical care, add their nonoverlapping qualifying time. The practitioner who furnished more than half the total time reports the service with modifier FS.
Can two physicians bill critical care for the same patient on the same date?
Physicians of different specialties may each report medically necessary, nonduplicative critical care. Physicians of the same specialty in the same group are treated as one for reporting purposes, and their nonoverlapping time is combined.
Does an ICU admission automatically qualify for 99291?
No. Documentation must support an acute threat to a vital organ system, a high likelihood of imminent, life-threatening deterioration, the critical care provided, and at least 30 minutes of qualifying time.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
