Z13 — Encounter for screening for other diseases and disorders

Not billable

Is Z13 billable?

No — Z13 is a non-billable header code. Z13 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 30 billable codes beneath Z13.
