T46.0 — Poisoning by, adverse effect of and underdosing of cardiac-stimulant glycosides and drugs of similar action
Is T46.0 billable?
No — T46.0 is a non-billable header code. T46.0 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 18 billable codes beneath T46.0.
