What is ultrafiltration in dialysis?
Ultrafiltration is the removal of fluid from a patient and is one of the functions of the kidneys that dialysis treatment replaces. Ultrafiltration occurs when fluid passes across a semipermeable membrane (a membrane that allows some substances to pass through but not others) due to a driving pressure.
How is the rate of ultrafiltration determined?
The ultrafiltration rate, as well as length of dialysis treatment time, control the amount of fluid to be removed. Your dialysis staff will set the ultrafiltration rate of your treatment based on your fluid weight gain since your last treatment. The goal is to get to your target or “dry weight”.
What causes ultrafiltration to fail?
Ultrafiltration failure means there is not enough fluid crossing the peritoneal membrane. Some things that can cause ultrafiltration to fail include uremia (high blood urea nitrogen), peritonitis (infection of the peritoneal membrane), and high dextrose PD solution (especially 4.25%). These factors cause inflammation of the peritoneal membrane.
How do I increase ultrafiltration?
Ultrafiltration can be increased by increasing the amount of dextrose in the PD solution. PD solutions are available with 3 different amounts of dextrose: 1.5%, 2.5%, and 4.25%. Your PD clinician may tell you to increase the dialysate dextrose if their body weight goes above your target weight.
How does hemofiltration work?
Hemofiltration (which is also known as diafiltration) is a covered procedure under Medicare and is a safe and effective technique for the treatment of ESRD patients and an alternative to peritoneal dialysis and hemodialysis. In contrast to both hemodialysis and peritoneal dialysis treatments, which eliminate dissolved substances via diffusion across semipermeable membranes, hemofiltration mimics the filtration process of the normal kidney. The technique requires an arteriovenous access. Hemofiltration may be performed either in facility or at home.
Does predialysis require additional staff?
While the predialysis ultrafiltration procedure requires additional staff care, the facility dialysis rate is intended to cover the full range of complicated and uncomplicated nonacute dialysis treatments. Therefore, no additional facility charge is recognized for predialysis ultrafiltration. The physician's role in ultrafiltration varies with the stability of the patient's condition. In unstable patients, the physician may need to be present at the initiation of dialysis, and available either in- house or in close proximity to monitor the patient carefully. In patients who are relatively stable, but who seem to accumulate excessive weight gain, the procedure requires only a modest increase in physician involvement over routine outpatient hemodialysis.
Can ultrafiltration be performed separately from dialysis?
Occasionally, medical complications may occur which require that ultrafiltration be performed separate from the dialysis treatment, and in these cases an additional charge can be recognized. However, the claim must be documented as to why the ultrafiltration could not have been performed at the same time as the dialysis.
Is ultrafiltration a substitute for dialysis?
This 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 utilized in cases where excess fluid cannot be removed easily during the regular course of hemodialysis. When it is performed, it is commonly done during the first hour or two of each hemodialysis on patients who, e.g., have refractory edema. Ultrafiltration is a covered procedure under the Medicare program (effective for services performed on and after September 1, 1979).
Can hemoperfusion be performed concurrently with dialysis?
One or two treatments are usually all that is necessary to remove the toxic compound; document additional treatments. Hemoperfusion may be performed concurrently with dialysis, and in those cases payment for the hemoperfusion reflects only the additional care rendered over and above the care given with dialysis.
Is hemoperfusion a covered service?
This is a process which removes substances from the blood using a charcoal or resin artificial kidney. When used in the treatment of life threatening drug overdose, hemoperfusion is a covered service for patients with or without renal failure. Hemoperfusion generally requires a physician to be present to initiate treatment and to be present in the hospital or an adjacent medical office during the entire procedure, as changes may be sudden. Special staff training and equipment are required.

How does PD work?
Peritoneal dialysis (PD) removes fluid by ultrafiltration using the lining of your belly (called the peritoneal membrane). Water moves from the blood to the P D solution through the peritoneal membrane due to a type of sugar in the dialysate solution called dextrose. Ultrafiltration can be increased by increasing the amount ...
How does ultrafiltration work in hemodialysis?
Ultrafiltration in Hemodialysis. In hemodialysis, fluid is removed by ultrafiltration using the dialysis membran e. The pressure on the dialysate side is lower so water moves from the blood (place of higher pressure) to the dialysate (place of lower pressure). This is how the hemodialysis treatment removes fluid.
