D0272 Dental Code: Two Bitewing X-Rays Billing Guide

What D0272 covers

D0272 reports a set of two bitewing radiographic images. A bitewing shows the crowns of the upper and lower teeth in one view with the contact points lined up, so the dentist can read interproximal decay and check the bone crest. Two images is the standard recall set for an adult with healthy posterior segments.

The code is defined by count: exactly two images, billed as a single line. The whole bitewing family codes by how many images you take, not by which teeth they show.

It does not cover:

• One bitewing image. That is D0270.
• Three bitewings (D0273) or four bitewings (D0274).
• A vertical bitewing set of seven to eight images. That is D0277, used for periodontal bone-level assessment.
• A periapical, which shows the full tooth down to the root tip. The first is D0220 and each additional one is D0230.
• A full intraoral complete series. That is D0210.

When to bill D0272

Bill D0272 when the office captures exactly two bitewing images in the session. For a typical adult recall that is a left and a right posterior bitewing, enough to read the contacts on both sides.

If the count is different, the code is different. One image drops to D0270; three or four step up to D0273 or D0274. Match the code to what the assistant actually took.

How D0272 fits the bitewing family

The codes step up purely by image count:

• D0270 is one bitewing image.
• D0272 is two.
• D0273 is three.
• D0274 is four.
• D0277 is a vertical bitewing series of seven to eight images, used when the clinical question is alveolar bone level rather than interproximal decay.

There is no “bill per image and let the carrier add them up” rule. The set codes exist so a multi-image bitewing session bills as one line.

Bitewings versus periapicals versus the full series

Keeping these lanes separate prevents most diagnostic-imaging adjustments:

• A bitewing (D0270 through D0277) is an interproximal view: crowns and bone crest on the back teeth, not the root tips. It finds decay between teeth and reads early bone loss.
• A periapical (D0220 first, D0230 each additional) captures the whole tooth, crown through root apex, plus surrounding bone. It answers root-level questions: abscess, fracture, retained root, pre-extraction.
• A panoramic (D0330) is a single extraoral image of both arches, the jaws, and the sinuses.
• A complete series (D0210) is a comprehensive intraoral set, usually fourteen to twenty-two films combining periapicals and bitewings, meant to show the entire mouth.

A panoramic plus a couple of bitewings is not a complete series. Reporting that mix as D0210 is a known error and a clean reason for a carrier to adjust the claim.

Frequency limits and downcoding

Bitewings are heavily frequency-restricted. Most plans allow a bitewing set on a set interval, commonly once or twice per benefit year, and the allowance pools the whole bitewing family rather than tracking D0272 on its own. A set taken inside the window pays; one taken outside it denies on frequency.

Separately, some plans cap the bitewing benefit at the single-image rate and reimburse a two-image set as if it were one bitewing. On the EOB that reads like a downcode from D0272 to D0270. That is plan benefit design, not a coding correction. Bill the code that matches the images; read the reimbursement off the EOB and bill the patient any balance the plan rules allow.

The interval, the reset basis, and any pediatric variation are all set by the individual plan. Treat the numbers as plan-dependent and confirm them during verification.

Documentation that supports the claim

A routine recall set rarely needs a narrative. When a carrier asks, the supporting facts are short:

• The teeth or quadrants imaged and the clinical reason (recall, decay check, contact concern).
• The date of the prior bitewings, so a frequency question answers itself.
• The images, attached when requested or when the visit falls outside the normal recall pattern.

Keep the prior-bitewing date where the billing team can see it. Most D0272 denials are frequency denials, and those resolve fast when the history is in front of you.

What to get right in your PMS

1. Bill the set as one line. Two bitewings is one D0272, not two units of D0270.
2. Code by image count. One is D0270, two is D0272, four is D0274. Match the code to the films taken.
3. Track the bitewing frequency per patient. The limit pools the family, so keep the last-taken date visible to the submitter.
4. Read downcodes off the EOB, don’t change the code. If a plan pays a two-image set at the single rate, that is benefit design. Submit D0272 for two images and post what the plan allows.
