A skimpy 53% of seniors on Medicare have dental insurance and the number who have vision and hearing is even slimmer. House Democrats this week have introduced a bill that, if passed, would expand Medicare benefits to include these three critical elements. 76 Democrats signed on to this legislation introduced by Lloyd Doggett (D-TX) which would add preventative dental, vision and hearing to Medicare Part B. Democrats intend to include this in a budget reconciliation bill that will move through the Chamber this fall.
