A CBO is a legal term and is defined in US Code Title 20, Chapter 70,Subchapter IXPart A § 7801 as follows:

"(6)Community-based organizationThe term “community-based organization” means a public or private nonprofit organization of demonstrated effectiveness that—
(A) is representative of a community or significant segments of a community; and
(B) provides educational or related services to individuals in the community."

Not sure there is any law requiring a formal recognition. However, OMB circular A-119 defines "Voluntary Consensus Standards", which I believe the AMA safety code may meet.

In short there is no need for a formal precognition nor does the AMA need to announce they are such. Just as the USHPA do not say they are a CBO, yet they are. See their site here .

They say they are a community but not a CBO.
