They're not lying though, at least if you're talking about a hospital. It's not an accident either, there's a strong norm in medicine about ignoring costs. Doctors aren't supposed to take cost into consideration when making medical decisions, to the point where they have no idea what anything costs and they fight to keep it that way.
That's the key, isn't it? Doctors tend to believe their services improve quality of life regardless of expenses. They need to be more aware of the long term reduction of quality of life caused by expenses.
Things are changing... very slowly.
