Z40 — Encounter for prophylactic surgery

Not billable

Is Z40 billable?

No — Z40 is a non-billable header code. Z40 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 9 billable codes beneath Z40.
