K46 — Unspecified abdominal hernia
Is K46 billable?
No — K46 is a non-billable header code. K46 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 3 billable codes beneath K46.
