D0274 dental code explained
D0274 usually means your dentist took four side-view X-ray images — two on each side of your mouth — by having you bite down on small tabs to capture the upper and lower back teeth together

What D0274 means
Four bitewing images are the standard X-ray set for most adults at a routine checkup, covering both premolars and molars on the left and right sides. This fuller set gives your dentist a more complete picture for detecting cavities between teeth and monitoring bone health around all your back teeth.
Average negotiated rates
Benchmarks are based on published negotiated-rate data available to MyBillRx. Your actual allowed amount depends on plan, network, geography, provider contract, and whether the claim is processed in-network.
What insurance typically checks
- • Most adult dental plans treat four bitewing images as the standard covered set — confirm your plan's frequency limit, which is commonly once every 12 to 24 months.
- • Check whether your plan covers D0274 at the same benefit percentage as preventive or basic services, since classification varies by insurer and affects your share of the cost.
- • Make sure the claim includes the date of your most recent prior bitewing X-rays, as insurers use that date to enforce frequency limits across all dental providers you have visited.
- • If you recently switched dental plans or dentists, verify that your new insurer has access to your prior X-ray history so a frequency denial is not issued in error.
Common denial or downcoding reasons
- • Frequency limitation — a prior bitewing claim on file, possibly from a different dentist or insurance plan, falls within the plan's waiting period.
- • Downcoding to D0272 — some insurers may reduce payment to the two-image rate if they determine four images were not documented as necessary for your situation.
- • Bundling with a comprehensive exam — certain plans will not pay separately for X-rays taken on the same day as a new patient or comprehensive examination.
- • Incorrect patient age category — some plans apply different frequency rules for adults versus children, and a coding mismatch can trigger a denial or reduced benefit.
What to ask your dentist
- • Is four bitewing images the right number for my mouth, or could two images have covered my needs just as well?
- • When were my last bitewing X-rays taken, and did you check whether my insurance frequency limit has reset before submitting the claim?
- • If my plan downcodes this to D0272, how much more will I owe and can your office appeal that decision?
- • Are these X-rays stored digitally, and can I get a copy to bring to another dentist if I switch providers?
What to check before you pay
- • Confirm the code on the bill matches the code on the EOB.
- • Check whether insurance allowed the charge, denied it, or downcoded it.
- • Compare the provider's billed charge to the negotiated or allowed amount.
- • Ask the office for the clinical reason if the code does not match what you remember receiving.
- • Compare diagnostic codes against frequency limits. Many plans limit exams, bitewings, and panoramic X-rays by time period.
FAQs about D0274
Why did my dentist take four X-rays instead of two?
Four bitewing images give a more complete view of all the back teeth in adults, covering both the premolar and molar areas on each side. Two images may miss cavities or bone changes in areas not captured by a smaller set.
My EOB says my plan only paid for two bitewing images but my dentist took four — what happened?
Your insurer may have downcoded D0274 to D0272, meaning they only paid the benefit for two images. This can happen if your plan limits coverage or if documentation supporting the need for four images was not included. Ask your dentist's office to review the claim and consider filing an appeal.
How often will insurance typically pay for four bitewing X-rays?
Most adult plans cover a four-bitewing set once every 12 to 24 months, though the exact interval depends on your specific plan. Some plans allow more frequent coverage for patients with a high cavity risk if the dentist provides a clinical reason.
Does it cost more out of pocket to have four bitewing images versus two?
If your plan covers D0274 as the standard adult set, your cost may be the same as for two images. However, if your plan only covers two images and your dentist took four, you may owe the difference. Always check your plan's schedule of benefits before your appointment.
