About 99184: Therapeutic hypothermia management for ill neonate

Reports physician management of therapeutic hypothermia for an ill newborn, commonly during treatment of neonatal encephalopathy after perinatal hypoxia.

This code describes physician management of therapeutic cooling for an ill newborn. A typical clinical setting is a neonatal intensive care unit treating an infant with hypoxic-ischemic encephalopathy after a complicated delivery. The neonatologist or another qualified physician manages the cooling treatment and the infant’s clinical response; the code is not for routine temperature control or simply placing the infant on a cooling device.

The record should support the medical reason for cooling and the provider’s management of that treatment, including relevant temperature and clinical monitoring. Report the service only when the physician’s work specifically includes management of therapeutic hypothermia. CMS fee schedule data assigns work, practice-expense, and malpractice RVUs to the service. When neonatal critical care is also reported, documentation should distinguish the hypothermia management from the separately reported critical care service.

99184 billing questions

When should this code be selected instead of neonatal critical care?

Use this code for physician management of therapeutic cooling itself. Neonatal critical care codes describe the broader critical care service; documentation should show the distinct work for each reported service.

Does placing a newborn on a cooling device support this code?

Device placement alone is not the service described here. The record should support physician management of therapeutic hypothermia and the infant’s response to treatment.

Can this be reported with a neonatal critical care code?

The services may occur during the same encounter. Document the therapeutic hypothermia management separately from the work supporting neonatal critical care.

How does this differ from anesthesia-related hypothermia coding?

This code concerns therapeutic cooling management for an ill neonate. Code 99116 concerns total-body hypothermia as an anesthesia circumstance, not neonatal treatment of encephalopathy.

What clinical documentation is most useful?

Record the indication for cooling, the provider’s management, and relevant temperature and clinical monitoring. A device log without documentation of physician management does not establish the service.
