Z49: Care involving dialysis

The group of conditions known as Care Involving Dialysis (coded as Z49 in the ICD-10 WHO 2016 classification) comprise situations in which a patient is undergoing dialysis. Dialysis is a medical procedure that performs the job of the kidneys when they're not able to. This can happen in case of chronic kidney disease or acute kidney damage. Symptoms that may lead to dialysis include a decline in urine output, swelling in the legs, ankles, and around the eyes, unexplained shortness of breath, fatigue, persistent nausea, and confusion. Dialysis helps by removing waste, salt, and extra water from the body and maintaining safe levels of certain chemicals in the blood. There are primarily two kinds of dialysis - hemodialysis where blood is cleaned in a machine outside the body and peritoneal dialysis where the cleaning is done inside the body. Both procedures require regular sessions, potentially extending over years if the kidney function does not recover.
