What Public CMS Data Show
Behavior Analyst: NPPES taxonomy is a reported classification, not proof of board certification.

Medicare assignment applies to Original Medicare. It does not tell you whether the clinician is in a Medicare Advantage plan's network, accepts other insurance, or is taking new patients.
