Ultrafiltration
Ultrafiltration (revenue code 0881) is a process for removing excess fluid from the blood
through the dialysis membrane by means of pressure. It is not a substitute for dialysis.
Ultrafiltration is used in cases where excess fluid cannot be removed easily during the
regular course of hemodialysis. It is commonly done during the first hour or two of
hemodialysis on patients who, for example, have refractory edema.
Pre-dialysis Ultrafiltration - While the need, if any, for pre-dialysis ultrafiltration varies
from patient to patient, the facility’s PPS rate covers the full range of complicated and
uncomplicated outpatient dialysis treatments. Therefore, no additional charge is
recognized for pre-dialysis ultrafiltration.
Separate Ultrafiltration - Occasionally, medical complications require that
ultrafiltration be performed at a time other than when a dialysis treatment is given, and in
these cases an additional payment may be made. However, the need for separate
ultrafiltration must be documented in the medical record and a supporting other diagnosis
must be included on the claim.
