2025 ICD-10-CM code Z49.32

Encounter for adequacy testing for peritoneal dialysis.

A corresponding procedure code must accompany a Z code if a procedure is performed. Code also: associated end stage renal disease (N18.6)

Medical necessity for this code is established by the need to monitor and adjust peritoneal dialysis to ensure its effectiveness in managing end-stage renal disease. Regular assessment of dialysis adequacy is essential for optimal patient outcomes.

The physician or other healthcare professional is responsible for performing and interpreting the peritoneal equilibration test (PET), which is used to assess the adequacy of peritoneal dialysis. This involves evaluating the transport of solutes and fluids across the peritoneal membrane.

In simple words: This code is used when a patient is seen by a healthcare professional for testing to ensure their peritoneal dialysis is working effectively.

This code is used for an encounter for adequacy testing for peritoneal dialysis.

Example 1: A patient with end-stage renal disease receiving peritoneal dialysis is seen for their regular PET to assess dialysis adequacy., A patient new to peritoneal dialysis is seen for a PET to determine the appropriate dialysis prescription., A patient experiencing symptoms of inadequate dialysis, such as fluid overload or uremia, undergoes a PET to evaluate the need for adjustments to their treatment.

Documentation should include details of the PET, including dwell times, dialysate volumes, and laboratory results. The physician's interpretation of the test and any resulting changes to the dialysis prescription should also be documented.
