Key data
| Regulation | Resolution of May 29, 2026, from the Under-Secretariat, publishing the Agreement between INSS, TGSS and INGESA for the transfer of information on affiliation matters |
|---|---|
| Publication | June 4, 2026 |
| Effective date | May 4, 2026 |
| Affected parties | Workers and companies in Ceuta and Melilla with temporary disability processes |
| Category | Social Security |
| Year | 2026 |
| Organizations involved | INSS (National Institute of Social Security), TGSS (General Treasury of Social Security), INGESA (National Institute of Health Management) |
| Legal basis | Article 77.1 of TRLGSS and principles of inter-administrative cooperation of Law 40/2015 |
Doctors at INGESA in Ceuta and Melilla no longer depend solely on what workers tell them about their occupation to assess medical leave. Thanks to the agreement published on June 4, 2026, INSS can transmit to INGESA the occupational data held by TGSS, allowing for an objective and verified assessment of temporary disability.
The regulation is based on Article 77.1 of the Consolidated Text of the General Social Security Law (TRLGSS) and on the principles of inter-administrative cooperation set out in Law 40/2015. Its scope of application is exclusively Ceuta and Melilla, the two autonomous cities where INGESA manages public health instead of an autonomous community.
What does this regulation establish?
The agreement creates a formal framework for the transfer of affiliation data between three Social Security organizations:
| Organization | Role in the agreement |
|---|---|
| INSS (National Institute of Social Security) | Transmits to INGESA the worker's occupational data obtained from TGSS |
| TGSS (General Treasury of Social Security) | Source of worker affiliation and occupational data |
| INGESA (National Institute of Health Management) | Data recipient; uses it to objectively assess temporary disability in Ceuta and Melilla |
Until this agreement came into force, the INGESA doctor only had information that the worker themselves communicated about their usual work. This left room for inaccuracies or inexact statements that could affect the assessment of leave. With the new data flow, the physician can verify what the worker declared against the official affiliation data registered in TGSS.
The agreement does not modify the medical criteria for granting leave or alter worker rights, but it does strengthen the information base on which these decisions are made.
Economic and operational impact
The direct economic impact of this regulation is limited and geographically restricted to Ceuta and Melilla. There are no new costs or economic obligations for companies arising from the agreement itself.
The operational impact, however, is relevant for companies in both cities:
- Greater precision in sick leave issuance: with objective occupational data available, leave will be issued with better knowledge of the worker's actual job position.
- Greater control over temporary disability: companies can expect more rigorous management of temporary disability processes, which may reduce the number of leave certificates issued with incomplete or incorrect information.
- No new administrative obligations for the company: data exchange occurs between public organizations (INSS, TGSS and INGESA). The company does not need to do anything new or provide additional documentation.
Who does it affect?
- Companies with workers in Ceuta and/or Melilla that manage temporary disability processes.
- Workers affiliated with Social Security in Ceuta and Melilla who request or are in the process of medical leave managed by INGESA.
- INGESA doctors in Ceuta and Melilla, who will now have official occupational data to assess temporary disability.
- HR managers and labor advisors who advise companies with a presence in these autonomous cities.
The agreement does not affect companies or workers in the rest of Spain, where health management is the responsibility of autonomous communities and not INGESA.
Practical example
A worker at a distribution company in Melilla requests medical leave for lower back pain. Until now, the INGESA doctor only knew what the worker told him about his work: "I do office tasks." With the new agreement, the doctor can consult the affiliation and occupational data that the company has declared to TGSS and verify that the worker is registered as a warehouse assistant, an activity that involves physical effort. This objective information allows the physician to assess the disability with greater precision, adjusting the duration and conditions of the leave to the reality of the position.
For the company, this translates into management of temporary disability that is more aligned with the worker's actual work situation, without the company having to do any additional management.
What should companies do now?
- Verify that occupational data in TGSS is up to date: since INGESA will receive affiliation data directly from TGSS through INSS, it is essential that the company has the professional category and occupation of each worker correctly declared. Outdated data can generate discrepancies.
- Inform the HR department or labor advisory: communicate this change to those who manage medical leave in the company so they are aware of the new flow of information between organizations.
- Review active temporary disability processes in Ceuta and Melilla: if workers are currently on leave, verify that their professional category registered in Social Security matches their actual functions.
- No formal action is required before INSS, TGSS or INGESA: the agreement operates between public organizations. The company does not need to submit documentation or request anything.
Frequently asked questions
What specific data does INSS share with INGESA?
INSS transmits to INGESA the worker's occupational data held by TGSS. This data comes from the affiliation register and allows the INGESA doctor to know the worker's actual work activity, beyond what they declare in consultation.
Does this agreement affect companies outside Ceuta and Melilla?
No. The scope of application is exclusively Ceuta and Melilla, the two autonomous cities where INGESA manages public health. In the rest of Spain, health management is the responsibility of autonomous communities and this agreement does not apply to them.
When did this agreement come into force?
The agreement came into force on May 4, 2026, although it was published in the Official Gazette on June 4, 2026.
What legal basis supports this data exchange between organizations?
The agreement is based on Article 77.1 of the Consolidated Text of the General Social Security Law (TRLGSS) and on the principles of inter-administrative cooperation established in Law 40/2015.
Does this new data exchange have any cost for companies?
No. The agreement generates no cost or economic obligation for companies. Data exchange occurs entirely between public organizations (INSS, TGSS and INGESA), without the company having to perform any additional management or contribution.
