I don’t think AMA gets any money out of using ICD-9 or the forthcoming disaster of ICD-10, the diagnosis coding. They get it for CPT, the procedure coding, which isn’t changing, at least not yet. AMA was foolish to go along with ICD-10 initially, and came to its senses too soon to stop it.
The AMA is a liberal organization that does not speak for most physicians and hasn’t for at least the last 25 years. They are nothing more than an outdated overhyped liberal lobbying organization with delusions of relevance
