Measures from encounter data as opposed to having the plans generate HEDIS measures. HEDIS is a collection of performance measures and their definitions produced by the National Committee for Quality Assurance (NCQA).

A measure of red blood cell volume in the blood.

Simultaneous hemodialysis and hemofiltration which involves the removal of large volumes of fluid and fluid replacement to maintain hemodynamic stability. It requires the use of ultra pure dialysate or intravenous fluid for volume replacement. Also called high flux hemodiafiltration and double high flux hemodiafiltration.

A method of dialysis in which blood from a patient's body is circulated through an external device or machine and then returned to the patient's bloodstream. Such an artificial kidney machine is usually designed to remove fluids and metabolic end products from the bloodstream by placing the blood in contact with a semi-permeable membrane, which is bathed on one side by an appropriate chemical solution, referred to as dialysate.

This treatment is usually done in a dialysis facility but can be done at home with the proper training and supplies. HD uses a special filter (called a dialyzer or artifical kidney) to clean your blood. The filter connects to a machine. During treatment, your blood flows through tubes into the filter to clean out wastes and extra fluids. Then the newly cleaned blood flows through another set of tubes and back into your body (See dialysis and peritoneal dialysis.).

Fluid removal.

A potential flaw in management controls requiring management attention and possible corrective action.

A data dictionary that defines and cross-references the contents of all X12 transactions included in the HIPAA mandate. It is maintained by X12N/TG3.
