Is a new patient dental exam covered by insurance?
Usually yes, at or near 100% as preventive, but only once in a while. The new-patient exam (code D0150) is the full first exam with a new office: complete charting of every tooth, your health history, an oral cancer screening, and a treatment-plan baseline. Most plans pay it once per dentist or once every few years, and it uses one of your two yearly exam slots.
100%
Preventive, but once per dentist
1 per dentist
The common rule: one full exam per patient per office, or one every 3 years. Bill it twice for the same patient and the second denies.
Shares 2 per year
The new-patient exam pulls from the same two yearly exam slots as the checkup. A patient who switched offices mid-year may have none left.
D0120 after that
Payers expect every later visit to be the regular checkup code. Repeating D0150 for a patient of record is one of the most common exam denials.
New patient, day 1
A new patient walks in with nothing verified. A check run from the schedule the night before shows the exam count and the X-ray clock before they sit down.
What would a real check show for this patient's D0150?
Pick a sample plan and type your fee. This is the visibility a real-time check gives the desk for every actual patient, in under a second.

Why new-patient exams get denied
What happens after the new-patient exam
The first visit usually stacks up: the exam, a full-mouth X-ray series (D0210) or a panoramic (D0330), bitewings (D0274), and a cleaning (D1110). Each has its own frequency clock, and every one of them followed the patient from the old office. Then the treatment plan lands, and new patients often owe a deductible before a single filling or crown pays. The desk that verified the exam count, X-ray dates, deductible and remaining maximum the night before quotes the whole first visit with confidence.
D0150, quick answers
Is a new patient dental exam covered by insurance?
Most plans cover D0150 at or near 100% as preventive, typically once per dentist or once every 3 years.
Does the new-patient exam count as one of my two yearly exams?
On most plans, yes. It shares the same exam count as the regular checkup (D0120).
I switched dentists this year. Will the new exam be paid?
Only if you have an exam slot left. Two checkups at the old office this year usually means the new exam is denied or paid out of pocket.
Why was D0150 paid at the checkup rate?
Some plans reimburse the new-patient exam at the D0120 fee. The claim pays, just less than billed.
Does D0150 need prior authorization?
No. The risks are frequency and the once-per-dentist rule, both visible on the eligibility check before the visit.
