Infusion services
About 96361: Additional-hour intravenous hydration
Reports each additional hour of medically necessary intravenous fluid hydration beyond the initial hydration service, when supported by documented infusion time.
This add-on represents continued intravenous hydration after the initial hydration service, such as fluid replacement for dehydration or volume depletion. It is commonly administered by nursing staff in an outpatient office or emergency department under a clinician’s order. The fluids are given to replenish volume or hydration, not merely to deliver a medication or keep an IV line open.
Report units from the documented hydration time under CPT infusion time rules, not from the number of bags or access sites. The record should identify the fluids, clinical reason, and infusion start and stop times; when medication administration occurs during the encounter, distinguish hydration time from drug-infusion time. CMS classifies 96361 as an add-on that must be billed with a primary procedure and is paid within that procedure’s global period. It is an incident-to service and may be billed only when performed under physician supervision.

96361 billing questions
Can 96361 be billed by itself?
No. It is an add-on and must be reported with a primary procedure.
Does each fluid bag count as a unit?
No. Units are based on documented hydration infusion time under CPT time rules, not the number of containers.
Can 96361 be reported during a medication infusion encounter?
Yes, when hydration is separately medically necessary and its time is distinct from the medication infusion. Fluid used only as a medication carrier or to keep the line open does not establish separate hydration service.
How does 96361 differ from 96366?
96361 represents additional time for IV hydration. 96366 represents additional time for a therapeutic, prophylactic, or diagnostic drug infusion.
What documentation supports 96361?
Document the reason for hydration, the fluid administered, and start and stop times sufficient to support the additional time reported. The service must also meet the physician-supervision condition for incident-to billing.
