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.
Roof shingles are a roof covering consisting of individual overlapping elements. These elements are typically flat, rectangular shapes laid in courses from the bottom edge of the roof up, with each successive course overlapping the joints below. Shingles are made of various materials such as wood, slate, flagstone, fibre cement, metal, plastic, and composite material such as asphalt shingles. Ceramic roof tiles, which still dominate in Europe and some parts of Asia, are still usually called tiles.
