Insurance says I had this done too recently. What does that mean?
The short answer
Most plans limit how often they'll pay for a service, like two cleanings a year or one set of bitewing X-rays a year. Come back before the clock resets, and the plan sits that visit out.
Common frequency limits
These vary by plan, but typical examples look like this:
- Cleanings and checkups: twice per year
- Bitewing X-rays (the cavity-check X-rays): once per year
- Full set of X-rays or a panoramic X-ray: once every 3 to 5 years
- Replacing a crown, bridge, or denture on the same tooth: once every 5 years or more
Watch the fine print: “per year” vs. “every 6 months”
“Twice per calendar year” and “once every six months” sound like twins, but they aren't. Under a six-month rule, a cleaning on January 3 means your next covered cleaning can't happen before July 3. Under a calendar-year rule, any two dates in the year work. Ask which rule your plan uses before you book.
A limit isn't a medical recommendation
Frequency limits are about what the plan pays for, not what your mouth needs. Your dentist may reasonably recommend something more often, such as gum maintenance cleanings every three months after treatment for gum disease. You can still have the care. You just may pay for it yourself.
Asking the plan for an exception
If your dentist believes you needed the care sooner than your plan allows, they can resubmit the claim with a note explaining why. On review, some plans will make an exception to the frequency limit. Whether they do depends a lot on the plan, but it's usually worth asking. If the plan still says no, you can appeal.
What you'll owe
When a plan normally covers a service but a frequency limit blocks payment, a dentist in your network usually still has to charge the plan's contracted fee, not their full fee. This can vary from plan to plan.
Switching dentists?
Services from your previous dentist count toward the limit. Tell your new office the date of your last cleaning and X-rays.
Questions to ask
- When was my last covered cleaning and X-ray, according to my plan?
- Does my plan count by calendar year or by months between visits?
- Is there a clinical reason I need this sooner than my plan covers?
- If so, can you resubmit the claim with a note explaining why?
