Is my toddler's first dental exam covered by insurance?
Usually yes, at 100%, as long as the child is under three and the plan includes children. The under-three exam (code D0145) is the first-tooth visit: the dentist checks the baby teeth and gums with a parent in the room and talks through feeding, thumb and pacifier habits, and how to brush. On the third birthday, most plans stop paying this code and expect a regular checkup exam instead.
100%
Preventive, under age 3 only
Under age 3
The hard line. Most payers stop paying D0145 on the third birthday, and the visit two days later needs a regular checkup code (D0120) instead.
Twice a year
Same exam bucket as every other evaluation. A toddler seen at a pediatric office and then at the family dentist can run out of slots.
Child on the plan?
Dependent coverage is the real question. A newborn not yet added to the parent's plan shows no coverage at all, and the claim comes back as no patient found.
Fluoride same day
The first visit usually adds fluoride varnish (D1206), which has its own frequency and age rules. One check shows both answers before the family arrives.
What would a real check show for this patient's D0145?
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.

When D0145 is the right code
- Child is under three years old on the visit date
- A parent or caregiver is present and counseled
- Dentist checks the baby teeth, gums and bite
- Not billed alongside another exam code that day
Documentation payers expect
The child's date of birth on the claim, a note that the caregiver was counseled, and what was found. Age is the field payers check first.
Why toddler exams get denied
What happens after the toddler exam
The next visits stay in the same lane: exams every six months, fluoride varnish (D1206) each time, and on many plans nothing owed. Then the third birthday flips the exam code to D0120, and a few years later sealants (D1351) show up with their own age and tooth rules. The desk that pulls the child's dependent status, exam count and age limits before each visit never has to tell a parent that the free visit was not free.
D0145, quick answers
Is my toddler's first dental exam covered by insurance?
On most plans with child coverage, yes, at 100% with no deductible, as long as the child is under three.
What happens to D0145 after my child turns three?
Most payers stop paying it on the third birthday. From then on the visit is billed as a regular checkup exam (D0120).
How often will a plan pay for a toddler exam?
Typically twice a year, sharing the same exam count as every other evaluation code.
Why was the claim rejected as patient not found?
The child probably has not been added to the parent's plan yet. Dependents must be enrolled before any claim pays.
Does D0145 need prior authorization?
No. The two things that matter are the child's age and whether the dependent is active, both of which the eligibility check shows.
