CNAE codes for medical clinics and doctors' offices in Brazil

To prospect this segment, search codes 8630-5/03, 8630-5/02, 8630-5/01, 8640-2/02, 8650-0/03, 8650-0/04 as both primary and secondary CNAE, keep only active CNPJs, then filter by company size and city.
CNAE codes for medical clinics and practices
CNAE (Classificação Nacional de Atividades Econômicas) is Brazil's official activity classification. Every company registered with a CNPJ declares one primary CNAE and any number of secondary ones. These are the CNAE 2.3 subclasses most used by medical clinics and practices:
| CNAE | Official description (pt) | English | When it shows up |
|---|---|---|---|
8630-5/03 | Atividade médica ambulatorial restrita a consultas | Outpatient medical practice, consultations only | Doctors' offices, consultation-only clinics |
8630-5/02 | Atividade médica ambulatorial com recursos para realização de exames complementares | Outpatient practice with diagnostic exams | Clinics running exams on site |
8630-5/01 | Atividade médica ambulatorial com recursos para realização de procedimentos cirúrgicos | Outpatient practice with surgical procedures | Clinics doing minor and day surgery |
8640-2/02 | Laboratórios clínicos | Clinical laboratories | Clinical testing labs |
8650-0/03 | Atividades de psicologia e psicanálise | Psychology and psychoanalysis | Psychology practices |
8650-0/04 | Atividades de fisioterapia | Physiotherapy | Physiotherapy clinics |
Search primary and secondary CNAE
Many medical clinics and practices register their real activity as a secondary CNAE, because the CNPJ was opened under another primary activity or because they do more than one thing. Multidisciplinary clinics often combine 8630-5/03 with 8650-0/03 (psychology), 8650-0/04 (physiotherapy) or 8630-5/04 (dentistry). Filtering on the primary code alone misses part of the market.
