Intradialytic parenteral nutrition and intraperitoneal nutrition.

Intradialytic parenteral nutrition and intraperitoneal nutrition are methods to provide supplemental nutrition support to patients with chronic kidney disease (also referred to as end-stage renal disease) while they are receiving dialytic therapy. There has been considerable controversy over indications and benefits of intradialytic parenteral nutrition and intraperitoneal nutrition. A major stumbling block had been problematic reimbursement for the therapy under Medicare. Medicare Part D has alleviated some of the reimbursement obstacles and has increased interest in reexamining the benefits and burdens of supplemental nutrition support therapies for patients receiving dialysis.
