What 99466 covers
99466 covers face-to-face critical care provided by a physician or other qualified health care professional while a critically ill or injured child age 24 months or younger is being transported. A typical situation is an interfacility transfer for a child who needs ongoing intensive monitoring or treatment en route to a higher level of pediatric or neonatal care. The service is the clinician’s care during transport, not the ambulance trip itself.
Report 99466 for the first 30–74 minutes of clinical care during transport. For additional qualifying time, report 99467, the add-on code for each additional 30 minutes. Documentation should establish the child’s age and critical condition, the transport, the clinician’s face-to-face care, and the time spent providing it. The Medicare Physician Fee Schedule assigns work, practice-expense, and malpractice RVUs to this service; the applicable payment amount is displayed separately.

99466 billing questions
When should 99466 be chosen over 99467?
99466 reports the first 30–74 minutes of face-to-face critical care during transport. Report 99467 for each additional 30 minutes.
Does 99466 include the ambulance charge?
No. It reports the clinician’s critical care during transport, not the vehicle or ambulance transportation service.
What time should the record support?
Document the time spent providing face-to-face clinical care during transport, along with the child’s critical condition and care provided en route.
Can 99466 be reported with critical care at the destination?
The transport service describes care during the trip; critical care furnished separately at the destination is a different service. Document the distinct care and its own time.
Does the patient’s age affect code selection?
Yes. 99466 is for transport critical care involving a child age 24 months or younger. The record should support the patient’s age.
