D0230: Intraoral, Periapical Each Additional Radiographic Image
Definition
D0230 is the CDT code for each extra periapical x-ray taken at the same visit, after the first one billed as D0220.
Why it matters for the front desk
When the dentist takes several periapicals at one visit, only the first is billed as D0220 and every one after it is D0230. Billing them all as D0220 is a common error that gets claims denied. Many plans also have a rule that when enough periapicals and bitewings are taken on the same day, they’re paid as a full mouth series (D0210). If the patient had a full series recently, some of those images may not be covered.
