CDT Code D0460: Pulp Vitality Testing

What Is D0460? (CDT Code Overview)

CDT code D0460 — Pulp Vitality Testing — falls under the Diagnostic category of CDT codes, specifically within the Tests and Examinations subcategory.

Remember that D0460 should not be used routinely in every examination, but only when there is a clear clinical reason.

Consider whether D0411 (HbA1c Point-of-Care Testing Explained) or D0412 (Blood Glucose Testing In-Office) might be more appropriate instead.
