WASHINGTON (AP) — Leading senators are urging Medicare to allow seniors concerned about their drug plan pick for next year to switch if they received inaccurate information due to changes the agency made this sign-up season. The request from 14 Democrats and one Independent comes as open enrollment for prescription drug coverage ends at midnight. Medicare hinted Friday in a statement that it will provide such second chances. But the agency said it will post details when sign-up season is over, because a policy announcement now might create confusion. Medicare revamped its online plan finder this year and the senators said they’ve gotten numerous complaints from people in their states about inaccurate information on drug pricing and coverage.
