Phone-verified provider directories

Half of every plan's provider directory is wrong. Ghostline calls to find out which half.

CMS found 48.74% of Medicare Advantage directory locations had at least one error; upkeep runs U.S. practices $2.76B a year; the REAL Health Providers Act now makes measuring accuracy a federal obligation.

Ghostline takes a directory, calls each office through CALL-E, and returns a verdict for every claim — with the front desk's exact words as evidence. It never returns one it can't quote. The engine is domain-neutral; healthcare is where the money is.
