SIC and industry classification for US hematologists
US hematologists aren't separately selectable in the standard SIC 1987 classification. The closest SIC 1987 umbrella is 8011 (Offices and Clinics of Doctors of Medicine). We use the CompanyData industry label 'Physicians: Blood Diseases (haematology)' to identify them precisely.
