CPT isn’t just a billing tool. It’s the private language that defines what American medicine can see, name, measure, and pay for. In this episode, we step beyond the economics and look at CPT as a culture — a worldview that shapes how clinicians work, how innovation enters the system, and how care is constrained by a vocabulary built for a vanished era. When one organization owns the language of medicine, it owns the contours of care. This episode explores how that culture formed, what it overlooks, and why modern medicine is forced to speak in a syntax that no longer fits the work.
