Which severity of chronic kidney disease does code N18.6 represent?

The code N18.6 specifically designates "End-stage renal disease," which is a critical stage in the progression of chronic kidney disease (CKD). In this stage, the kidneys have lost most of their ability to function, leading to a complete reliance on dialysis or a kidney transplant for survival.

Understanding the context of CKD severity helps clarify the distinction between the stages. Mild and moderate include earlier stages of kidney impairment, characterized by varying levels of decreased kidney function but with the kidneys still able to carry out some essential tasks. Severe CKD indicates a further decline in kidney functionality, yet patients might not yet be at the end-stage.

In contrast, end-stage renal disease reflects a dramatic decrease in kidney capability, necessitating regular dialysis or prompting consideration for transplant options. Recognizing the terminologies and implications of each stage is crucial for accurate coding and optimal patient management in clinical settings.
