What 99464 covers
A pediatrician, neonatologist, or other clinician may be called to the birthing room when the delivering physician anticipates a newborn who may need immediate assessment or stabilization. The service covers presence at the delivery and initial care of the newborn, such as evaluating the infant’s condition and providing appropriate immediate support. The key circumstance is attendance requested by the delivering physician, not simply the clinician’s later examination of the newborn.
Document who requested attendance, why the clinician was called, the newborn’s condition at birth, the assessment and stabilization performed, and the disposition or handoff. Distinguish this service from active delivery-room resuscitation, which is addressed by 99465, and from a separate newborn evaluation after birth, such as 99460 or 99461. The CMS physician fee schedule valuation uses work, practice-expense, and malpractice RVUs; CMS lists the same practice-expense RVU for office and facility settings.

99464 billing questions
When should 99464 be selected instead of 99465?
Use 99464 for requested attendance and initial newborn assessment or stabilization. When active delivery-room resuscitation is performed, assess whether 99465 describes the service instead.
What documentation supports reporting 99464?
Record the delivering physician’s request, the reason for attendance, the newborn’s condition, the assessment and immediate support provided, and the handoff or disposition.
Can 99464 be reported with a newborn evaluation code?
A separate newborn evaluation, such as 99460 or 99461, describes care beyond delivery attendance. Document the distinct evaluation and services rather than relying only on the attendance record.
Does 99464 represent a timed service?
Documentation should describe the delivery attendance and newborn care performed, rather than relying on elapsed time.
Who must request the delivery attendance?
The service is for attendance requested by the delivering physician. Document the request and its clinical reason in the delivery record.
