Z49 — Encounter for care involving renal dialysis
Is Z49 billable?
No — Z49 is a non-billable header code. Z49 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 4 billable codes beneath Z49.
