What the count covers

22,803 NPPES records list case manager/care coordinator (171M00000X) as their primary taxonomy with a practice address in California: 59 per 100,000 residents against 48 nationally (50 states and D.C.). Los Angeles has 2,545 of them (11%).

A record is a registration a provider made and keeps up to date: it shows neither that the provider is licensed nor that they still practice there. The state's own license search is the check.
