D0210 is the CDT code for an intraoral complete series of radiographic images — the full-mouth set (FMX) that captures all teeth and surrounding bone, typically combining periapical and bitewing images.

When to Use the D0210 Code
Use D0210 when a complete intraoral series is taken — a full-mouth set capturing all tooth-bearing areas plus the surrounding bone, usually for a new-patient baseline, a comprehensive workup, or a periodic full update. The series generally includes a sufficient number of periapical and bitewing images to depict the entire dentition.
Don't bill D0210 when only a few films are taken. A single periapical is D0220 (first image) with D0230 for each additional, and bitewings have their own codes. A common billing error is reporting individual periapicals and bitewings that, taken together, amount to a complete series — payers often bundle those into D0210. Conversely, billing D0210 for a partial set is also incorrect.
Documentation & Clinical Scenarios
The record should support that a true complete series was taken:
- The date and clinical reason for the full-mouth series (new patient, comprehensive exam, or update).
- The images captured, confirming the series covers all tooth-bearing areas and surrounding bone.
- The interpretation/findings noted by the dentist.
- Prior imaging history, supporting that the frequency limit allows a new series.
The evaluation performed at the same visit (such as D0150) is reported separately under its own code. D0210 covers the imaging, not the exam.
Insurance & Billing Tips
- Know the frequency limit. Most plans cover a complete series only once every 3–5 years; a repeat sooner is commonly denied without a documented reason.
- Don't unbundle. Reporting many individual periapicals/bitewings that constitute a full series instead of D0210 can be re-bundled or flagged as overbilling.
- Combined limit with panoramic. Many plans count D0210 and a panoramic image (D0330) against the same frequency allowance.
- Document a clinical reason for early repeats. Trauma, new symptoms, or a treatment plan can justify a series before the usual interval, but expect to attach a narrative.
- Verify history. Check the patient's prior imaging dates to time the series within the benefit.
Example Case
A new adult patient with no recent records schedules a comprehensive first visit. The dentist orders a full-mouth radiographic series to establish a baseline, and the assistant captures the complete set of periapical and bitewing images covering the entire dentition. The imaging is coded D0210, and the comprehensive evaluation is reported separately as D0150. Because the office confirmed the patient had no complete series within the plan's 3-to-5-year window, the claim processes cleanly with the expected coverage.

Frequently Asked Questions
What's the difference between D0210 and D0220?
D0210 is a complete intraoral series — a full-mouth set capturing all teeth and surrounding bone — while D0220 is a single intraoral periapical (the first image), with D0230 for each additional periapical. The distinction matters for billing: taking enough individual films to make up a full series should generally be reported as D0210, not as a stack of separate periapical codes, which payers often re-bundle.
How often will insurance cover D0210?
Most plans cover a complete series only once every three to five years, and many apply that same frequency limit jointly to a panoramic image (D0330). A repeat series sooner is commonly denied unless there's a documented clinical reason — such as trauma, new symptoms, or a treatment plan. Verifying the patient's prior imaging dates before taking the series helps you bill within the benefit.
Does D0210 include the exam?
No. D0210 covers only the radiographic imaging. The evaluation performed at the same visit — for example a comprehensive exam (D0150) or periodic exam (D0120) — is reported separately under its own code. Each service is billed on its own line, and the chart should document both the imaging and the evaluation distinctly.
Can I bill individual X-rays instead of D0210?
Only if they don't add up to a complete series. If you take a few periapicals or bitewings for a focused purpose, those are reported under their own codes. But if the images captured together amount to a full-mouth series, payers generally expect D0210 and may re-bundle separately billed films. Reporting a complete set as individual codes can be flagged as unbundling, so match the code to what was actually taken.
