Orthodontic treatments are typically covered under the Delta Dental - Tricare Retiree (TRDP) plan, but the specifics can vary based on individual coverage and eligibility. Generally, orthodontic services, including braces and other treatments that correct misaligned teeth or jaws, may be covered for children under certain conditions. For adult orthodontic treatments, coverage may be more limited or may require a prior authorization depending on the specific plan provisions. It is important for members to review their specific policy documents to understand the details regarding coverage limits, eligible services, and any necessary documentation that may be required for claims. Additionally, members are encouraged to check the most current information on the official Delta Dental website to find more about their coverage options and any changes that may affect their benefits.
