D0230Intraoral Periapical Each Additional Radiographic Image

What This Code Covers

D0230 covers each additional intraoral periapical radiographic image taken after the first image (D0220) during the same patient visit. This code is billed per image, so if a dentist takes four periapical films in one visit, the claim would include one D0220 and three D0230 line items. It is used when the clinician needs to evaluate multiple specific teeth or areas but does not require a full mouth series. D0230 should never be billed on its own without a corresponding D0220 on the same date of service.

Billing Guide

Bill this code when:

• The dentist takes a second, third, or any subsequent periapical image during the same visit after the first image has been billed as D0220
• Multiple teeth in different areas of the mouth need individual periapical evaluation, such as when assessing several symptomatic teeth
• Follow-up imaging requires views of more than one tooth or area, and a full mouth series is not clinically indicated
• The additional images are each of a different tooth or area, providing distinct diagnostic information

Do not bill this code when:

• It is the first periapical image of the visit (use D0220 for the first image)
• No D0220 has been billed on the same date of service (D0230 must always accompany a D0220)
• The images are part of a full mouth series (use D0210 instead)
• The additional image is a retake of a prior film from the same visit due to poor quality or positioning (retakes are not separately billable)
• Bitewing images are being taken (use D0270 or D0272 for bitewings)
• The total number of individual periapical and bitewing images approaches a full mouth series, in which case D0210 may be more appropriate

Insurance and Denial Prevention

Key Payer Rules:

• Most payers require D0230 to be billed alongside D0220 and will deny D0230 if no D0220 appears on the same claim
• Some plans set a per-visit or per-year limit on the total number of periapical images allowed, combining D0220 and D0230 counts
• If the combined number of periapical and bitewing images approaches 14 or more, some payers may reclassify the claim as an FMX (D0210) and apply that code's frequency rules
• Medicaid programs may cap the total number of intraoral images per year, so track cumulative counts across visits

Common Denials and How to Respond:

• D0230 billed without D0220: Resubmit the claim with D0220 included as the first periapical image. If D0220 was accidentally omitted, correct the claim and add the appropriate line item
• Exceeds image limit: Appeal with a clinical narrative explaining why each image was necessary, listing the tooth number and diagnosis for every film. Attach the treatment notes showing distinct areas of concern
• Reclassified as FMX: If the payer downcodes multiple periapical images to D0210, respond with documentation showing that a targeted approach was clinically appropriate and that a full mouth series was not indicated
