Z46 — Encounter for fitting and adjustment of other devices
Is Z46 billable?
No — Z46 is a non-billable header code. Z46 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 12 billable codes beneath Z46.
