Counts are computed from the NPPES NPI Registry fields stored for the 72,892 doctor profiles in this directory (built 2026-10-08). They describe this directory only, not every clinician licensed in the state. Source: NPPES NPI Registry (CMS).
Search the doctor's name in the Medical Board of California license lookup to confirm an active license and see any public disciplinary actions. Then enter the NPI number from the doctor's profile in the NPPES NPI Registry to confirm the credential, specialty taxonomy and practice address on file. Board certification in Rheumatology is checked separately through the certifying board, for example the ABMS Certification Matters search.
Before you book a rheumatology doctor, check whether the practice is in your health plan's network (call the number on your insurance card), whether your plan needs a referral from a primary care doctor, the doctor's license status through the Medical Board of California, and board certification through the ABMS Certification Matters search. If you have Medicare, Medicare's Care Compare tool lets you search doctors and clinicians enrolled in Medicare. The Doctor Directory does not rate or rank doctors and does not give medical advice, so ask your own doctor which kind of specialist you need.
