In BlueCross BlueShield of South Carolina's open formulary benefit design, once a drug is FDA approved, we will cover it. Dual eligibles have gotten used to the open formulary under Medicaid, but some of Medicare's formularies might be closed, and we don't know what those will be.
Shingle(noun) a piece of wood sawed or rived thin and small, with one end thinner than the other, -- used in covering buildings, especially roofs, the thick ends of one row overlapping the thin ends of the row below.
The term shake is sometimes used as a colloquialism for all wood shingles, though shingles are sawn rather than split. In traditional usage, shake refers to the board to which the shingle is nailed, not the shingle. Split wooden shingles are referred to as shag shingles.
