Physicians at the SPS in Cantabria no longer have to rely solely on what the worker tells them about their usual occupation. As of June 15, 2026, the Agreement between the INSS, TGSS and the Autonomous Community of Cantabria allows them to directly access affiliation data registered with Social Security at the time of issuing a medical leave certificate for temporary disability.
The agreement is published through the Resolution of June 4, 2026 of the General Technical Secretariat (BOE-A-2026-13019) and takes effect immediately from its publication. Its stated objective is to improve the accuracy in the assessment of temporary disability and strengthen the control of these processes in their first 365 days.
What does this regulation establish?
The agreement creates a formal framework for data transfer between three organizations:
- National Institute of Social Security (INSS)
- General Treasury of Social Security (TGSS)
- Autonomous Community of Cantabria (through its Public Health Service)
The data transferred is the worker's usual occupation, as recorded in the TGSS affiliation registers. Until now, the doctor issuing the medical leave certificate depended on the information the patient provided about their job. With this agreement, the physician can verify that information against the official source.
The legal basis for this data transfer is article 77.1 of the consolidated text of the General Law on Social Security and Law 40/2015 on the Legal Regime of the Public Sector, which regulate collaboration mechanisms between administrations.
The scope of control is limited to the first 365 days of the temporary disability process, which is the period when medical leave management is primarily the responsibility of the primary care physician at the SPS and the INSS.
Economic and operational impact
This agreement does not generate direct costs for companies, but it does have relevant operational consequences for any employer with workers in Cantabria:
- Greater rigor in medical leave assessment: By having objective data on the worker's occupation, the doctor can evaluate with greater precision whether the condition is compatible with the physical or cognitive demands of the position. This may result in a stricter review of medical leaves that were previously granted with less information.
- Reduction of IT fraud: The availability of affiliation data in real time makes it difficult for a worker to declare an occupation different from the one registered to obtain or extend medical leave.
- Strengthened control in the first 365 days: This is the period where most of the IT cost for companies is concentrated (salary supplements, replacements, loss of productivity). More precise control can shorten unjustified processes.
- No impact on the company's administrative management: The agreement operates between administrations. The company does not have to perform any additional procedures or provide new documentation.
Who does it affect?
- Companies with workers in Cantabria: Any employer whose workers may take medical leave (IT) in this autonomous community. The agreement affects the assessment process of those medical leaves from day one.
- Workers on medical leave in Cantabria: Their usual occupation registered with the TGSS will be visible to the doctor issuing the certificate. The information they declare to the physician can be verified against official data.
- Doctors at the Public Health Service of Cantabria (SPS): They are the direct users of this data transfer. They will have objective information about the patient's position when assessing disability.
- INSS in Cantabria: It strengthens its ability to control and monitor IT processes in the first 365 days.
- HR managers and labor advisors with clients or employees in Cantabria: must be aware that the IT control environment in this community has become stricter.
Practical example
A worker registered as a warehouse laborer at a company in Cantabria visits his primary care doctor with back pain. When requesting medical leave, he tells the physician that his work is "administrative" and that he spends the day sitting, trying to obtain a more favorable assessment.
With the new agreement in effect, the doctor at the SPS in Cantabria can consult the TGSS affiliation data at that very moment. He verifies that the worker is registered as a warehouse laborer, an occupation with high physical demands. This objective information allows him to assess the medical leave with greater precision: if the back injury is compatible with that specific position, the medical leave may be fully justified; if the worker's statement does not match his actual occupation, the doctor has data for a more rigorous assessment.
The result: IT management more aligned with the reality of the job, with less room for inaccurate statements.
What should companies do now?
- Verify that the affiliation data of your workers in Cantabria is correct: If an employee is registered with a professional category that does not correspond to their actual position, this agreement may generate inconsistencies in the management of their medical leaves. Review the registration with the TGSS.
- Inform your workers in Cantabria of the new control environment: Not as a threat, but as relevant information: doctors at the SPS now have access to their registered occupation. Transparency prevents misunderstandings.
- Coordinate with your labor advisor or HR manager: If you manage IT processes in Cantabria, make sure your advisor is aware of this agreement and its implications for medical leave monitoring.
- Review IT supplements in your collective agreements: Stricter control of medical leaves may reduce the number of prolonged processes, with an impact on the costs of salary supplements that the company assumes during IT.
