As the name implies, DVH is a combination of Dental Insurance, Vision Insurance, and Hearing Insurance. However, these can be purchased separately if desired.
These plans help to reimburse or cover significant portions of regular examinations, x-rays, teeth cleaning, preventative services, eyeglass frames, etc. Plans vary in specific items, but help offset costs for more significant services, eye glasses, hearing aids and such.
You will want to review plan details and verify that there is coverage for specific products or services you are likely to need.
