If your dental insurance denied claim, it usually happens due to reasons like missing paperwork, errors in billing codes, treatment not being listed in your plan, or your benefits not being verified properly before the dental visit. Sometimes, insurance companies reject claims if the treatment is not seen as “medically necessary” or if you’re still in the waiting period. One of the biggest reasons, as explained on DentalInsuranceChecks.com, is that many dental offices forget to confirm your eligibility, benefits, and plan details before treatment, which leads to denials. So, what to do when dental insurance won’t pay? First, stay calm and contact both your dental office and insurance provider. Ask for the exact reason for the denial and request a written explanation. If the issue is minor, like a missing code or document, your dentist can correct it and resubmit the claim. Always keep copies of your dental records, bills, and communication. To avoid this in the future, make sure the office verifies your coverage in advance—including your annual limits, waiting period, and whether pre-approval is needed. If your claim is still denied, don’t hesitate to file an appeal with support from your dentist, explaining why the treatment was necessary. With the right steps and good communication, you can often get the issue resolved and protect yourself from paying out of pocket.
