Is a single dental X-ray covered by insurance?
Usually yes. Most plans pay a single close-up X-ray at 100% as preventive, and some file it under basic at 80%. The first close-up X-ray of a visit (code D0220) is one small picture of one tooth, top to root tip, taken to look at a specific problem: a toothache, a crack, an injury, or a tooth being watched. Extra pictures in the same visit use a different code.
100%
Usually preventive, as needed
As needed
No set yearly count on most plans, but payers watch the pattern. A close-up X-ray at every checkup with no problem noted starts to get questioned.
First film only
D0220 is the first close-up of the visit. Every additional one that day is D0230, and billing two D0220s on one date is a duplicate.
Recoded to FMX
Stack enough close-ups and bitewings in one visit and the payer pays the whole set as a full series (D0210) instead, and starts its 3 to 5 year clock.
Emergency pair
It rides along with the emergency exam (D0140). Whether both pay at 100% or one owes the deductible is plan-specific, and the check answers it while the patient signs in.

When D0220 is the right code
- One tooth needs a close look, crown to root tip
- A specific complaint or finding drives the image
- It is the first close-up X-ray of the visit
- Not part of a full series taken that day
Documentation payers expect
The image with the tooth number and date, plus a note naming the reason. A close-up with no reason in the chart is the one payers push back on.
Why single X-rays get denied
What happens after the single X-ray
A close-up X-ray is taken because something is wrong, so the next line on the bill is usually treatment: a filling (D2140 to D2393), a root canal (D3310 to D3330), a crown (D2740), or an extraction (D7140 or D7210). Each carries a different percentage, most sit behind the deductible, and a new plan may still be inside a waiting period. When the desk already has the basic and major percentages and the remaining maximum on screen, the fix gets quoted while the image is still up.
D0220, quick answers
Is a single dental X-ray covered by insurance?
Most plans pay D0220 at 100% as preventive; some treat it as basic at 80% behind the deductible.
How many close-up X-rays will a plan pay for?
There is usually no fixed count, but the payer expects a reason for each one and watches for routine use.
What is the difference between D0220 and D0230?
D0220 is the first close-up X-ray of the visit. Every additional one the same day is billed as D0230.
Why were my X-rays paid as a full series?
Enough close-ups plus bitewings in one visit get bundled into D0210 by the payer, which also starts the series frequency clock.
Does D0220 need prior authorization?
No. The risk is the plan's percentage and bundling rules, both of which the eligibility check shows before the image is taken.
