The categories of dialysis listed in §§BF of this regulation are recognized on the basis of differing facility requirements. Acute Dialysis. Acute dialysis is not reimbursable under the Kidney Disease Program and nothing in this subtitle is meant to refer to acute dialysis. Chronic Dialysis. Chronic dialysis may be provided in the dialysis facilities defined and described in this subtitle. Chronic dialysis may be preceded by adequate studies to confirm that the kidney failure is irreversible. Home Dialysis. A period of training in an approved home dialysis training facility is required before a patient can safely undergo dialysis treatments in the home. Home Training Dialysis. Home training dialysis is usually conducted in a center with simultaneous dialysis and instruction provided to the patient that includes the technique of performing the type of dialysis selected. The period required for this training differs depending on the individual circumstances, and requires the expertise and equipment necessary for providing adequate home training. A responsible third party may be included in the training. Chronic Peritoneal Dialysis. This process can substitute for kidney function that has been permanently lost and represents a permanent treatment unless replaced by either hemodialysis or kidney transplantation. Long-term care of end-stage kidney disease by chronic peritoneal dialysis may be carried out either in a dialysis facility or in the home. Nocturnal Hemodialysis. Nocturnal hemodialysis may be provided in the dialysis facilities defined and described in this subtitle.
