Defense-Insurers Agreement 2026-2029: what insurers pay for traffic accidents in military hospitals

Key data

Vehicle insurers operating in Spain have had a specific economic obligation since January 1, 2026: to assume the cost of healthcare assistance provided by military hospitals to occupants of the vehicles they insure when they suffer a traffic accident. The legal framework regulating this is the Resolution 420/38357/2026, published in the BOE on August 13, 2026, which publicizes the agreement signed on July 31, 2026 between the Ministry of Defense, UNESPA and the Insurance Compensation Consortium.

The agreement has a four-year validity period (2026-2029) and establishes with precision who pays, how much, within what timeframe and what happens when the vehicle is uninsured or has been stolen.

What does this regulation establish?

The agreement regulates the provision of healthcare assistance at the two military hospitals authorized to treat injured persons in traffic accidents:

• Central Defense Hospital — Madrid
• General Defense Hospital — Zaragoza

The cost allocation rules are as follows:

The rates applicable to each fiscal year are detailed in Annex I of the agreement for the years 2026, 2027, 2028 and 2029. Although the agreement is published in August 2026, the rates have retroactive effect from January 1, 2026.

Regarding billing deadlines, the agreement establishes a maximum limit of two years from the first assistance. This period may be extended until the stabilization of injuries in cases where future healthcare assistance is necessary.

Economic and operational impact

For vehicle insurers, the impact is twofold: economic and administrative.

Economic: Each insurer is responsible for occupants of the vehicle it insures. This means that the cost depends directly on the volume of automobile policies in the portfolio and actual claims experience in the areas of influence of the two military hospitals (Madrid and Zaragoza). The specific rates by type of assistance are in Annex I of the regulation for each of the four fiscal years.

Administrative: Insurers affiliated with UNESPA can claim payment from non-affiliated entities. The latter have 60 days to accept or reject the claim, which requires having agile internal review and response processes.

For the Insurance Compensation Consortium: It assumes cases without coverage (uninsured or stolen vehicles), which represents economic exposure linked to claims experience in that specific segment in the areas of influence of military hospitals.

For traffic accident victims: Assistance at military hospitals is financed at no direct cost to the injured party, as the agreement guarantees that there is always a responsible entity for payment (insurer or Consortium).

Who does it affect?

• Vehicle insurers affiliated with UNESPA: Obligated to assume the cost of assistance for occupants of the vehicles they insure treated at the military hospitals in Madrid and Zaragoza.
• Insurers not affiliated with UNESPA: May be claimed by affiliated insurers and have 60 days to accept or reject payment.
• Insurance Compensation Consortium: Covers cases of uninsured or stolen vehicles.
• Claims and recovery departments of insurers: Must adapt their processes to manage claims from military hospitals and from other insurers.
• Traffic accident victims treated at the Central Defense Hospital (Madrid) or the General Defense Hospital (Zaragoza).

Practical example

A driver insured with a company affiliated with UNESPA suffers a traffic accident in Madrid and is transferred to the Central Defense Hospital. The healthcare assistance received generates an invoice according to the rates in Annex I of the agreement for fiscal year 2026.

The driver's insurer is responsible for full payment of that invoice, with a maximum claim period of two years from the first assistance. If the driver needs future assistance for non-stabilized sequelae, the period is extended until the injuries are stabilized.

If the vehicle involved in the accident had no insurance or had been stolen, it would be the Insurance Compensation Consortium that would assume the cost of assistance provided by the military hospital, with the victim owing nothing.

If the same accident involves the classification of work-related accident in transit (the driver was going to work), the traffic accident classification prevails and the vehicle insurer pays, not the labor mutual.

What should companies do now?

1. Verify UNESPA affiliation: Confirm whether the company is affiliated with the agreement, as it determines direct payment obligations and rights to claim against third parties.
2. Review claims processes: Ensure that the claims department correctly identifies assistance provided at the Central Defense Hospital (Madrid) and the General Defense Hospital (Zaragoza) and processes it in accordance with the agreement.
3. Update reference rates: Incorporate the rates from Annex I of the agreement for 2026 (and those for subsequent fiscal years when published) into recovery management systems.
4. Establish a 60-day response protocol: Non-affiliated entities claimed by an affiliated one must accept or reject payment within that period. Define internally who manages these claims and within what timeframe.
5. Control the two-year billing deadline: Implement alerts to not exceed the maximum claim limit from the first assistance, except in cases of non-stabilized injuries.
6. Coordinate with the legal department on concurrent in-transit cases: When an accident may be classified simultaneously as traffic and work-related in transit, the agreement establishes that traffic classification prevails. Document these cases correctly to avoid disputes with labor mutuals.
