Summary & Overview
HCPCS S9007: Ultrafiltration Monitor
HCPCS Level II code S9007 denotes an ultrafiltration monitor, a durable medical device component used to measure and regulate fluid removal during treatments that require precise ultrafiltration control. Nationally, device-related HCPCS codes like S9007 matter because they affect billing for dialysis and fluid-management services across outpatient and inpatient settings and influence access to necessary monitoring equipment.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of payer coverage considerations, typical sites of service where S9007 is relevant (dialysis clinics, hospital units, outpatient infusion centers), and context on how this device-level code fits into service delivery for fluid removal therapies.
The publication outlines reimbursement benchmarks where available, common billing modifiers and coding practices for device and service lines, and implications for billing workflows. Operational and clinical audiences will gain clarity on documentation expectations tied to device monitoring and where to look for payer-specific policy language. Data not available in the input is signaled where necessary.
Billing Code Overview
HCPCS Level II code S9007 describes an ultrafiltration monitor, a device used to measure and control the removal of excess fluid from a patient during therapies that require precise fluid management. The service type is device monitoring/equipment for ultrafiltration, and the typical site of service is settings where ultrafiltration or fluid management procedures occur, such as dialysis clinics, hospital inpatient units, and outpatient infusion centers.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with end-stage heart failure and refractory volume overload is admitted for symptomatic fluid removal when diuretics are ineffective or contraindicated. The patient is connected to an extracorporeal ultrafiltration system in a monitored inpatient setting (cardiac care unit or specialized infusion/dialysis unit). An ultrafiltration monitor (billing code S9007) is used to continuously measure and display fluid removal rates, cumulative net ultrafiltrate, transmembrane pressures, and alarms during the procedure. Nursing and dialysis/critical care staff verify device setup, document baseline weights and hemodynamics, program target ultrafiltration rates, monitor vital signs and access site integrity, and record hourly net fluid removed. Typical workflow steps include pre-procedure assessment and order entry, device setup and verification, initiation of ultrafiltration with ongoing monitoring via the ultrafiltration monitor, documentation of hourly outputs and hemodynamic responses, adjustment of rates as indicated by the treating clinician, and formal discontinuation with post-procedure weight and access assessment. The typical site of service is an inpatient hospital unit (cardiac care unit or intensive care unit), hospital outpatient infusion/dialysis center, or specialized procedural suite for fluid management.
