“I need a cardiologist through the SUS, where do I start?” The question is universal and the answer is almost never what people expect: you do not book a specialist appointment directly. The SUS works through a system called “regulation”, and understanding how it operates is the difference between waiting months without news and actively tracking your place in the queue. This guide explains the path.
It all starts at the UBS
The specialist is reached by referral. You are seen by a doctor at the Basic Health Unit (UBS), who assesses you and, if appropriate, issues a referral to the specialty. Without that door, there is no queue to enter. So the first practical step is to be registered and seen at the UBS for your address, as detailed in our complete guide on how to use the SUS.
What “regulation” is
The referral does not go straight to a schedule: it enters a regulation system that organizes the queue by clinical priority and distributes the available slots across the network. Those with more serious conditions are ranked with higher priority. This means the queue is not simply first-come, first-served, and that the quality of the referral, with the correct clinical description, influences your ranking.
How to track it (and not fall off the list)
- Confirm the referral actually entered regulation. Ask the UBS for the receipt or request number. A referral left in a drawer generates no queue.
- Keep your phone and address up to date in the registry. The call comes by contact: a lost number is a lost slot.
- Track it through the Meu SUS Digital app and return to the UBS periodically to confirm you are still in the queue.
- Consider “Agora Tem Especialistas”. The slot may come at a private clinic or hospital contracted by the SUS, at no cost, through the program explained in free specialist care through the SUS.
When the wait goes beyond reasonable
Unlike private insurance, the SUS has no single deadline set in a rule for each appointment, but the wait cannot be indefinite when your health is at risk. The first steps are administrative: the SUS Ombudsman (phone 136) and the city health department, responsible for regulation. When the delay threatens your health, there is a judicial route, and cancer cases have their own, stricter rule, in the 60-day law.
