1932    Act IV of 1932 abolishes the system in place, offering the opportunity to proceed with lawsuits without having to request the opinion of medical experts.

1945-1947    After the Second World War, medical expert activity was primarily restricted to determining 100% war injury. Opinions were issued by licensed medical consultants and medical consultants of the armed forces.

1948     The Accident Medical Council and the Central Senior Medical Consultant Review was merged and continued to operate as the Unit for Disability Determination and Review. Appeals lodged were assessed at the District Court and the High Court. 

1951    Due to significant discrepancies between first and second instance decisions, the Department of Health set up Medical Committees Assessing Decreased Work Capacity at the end of 1951, which was commonly known as MUCSÖ.
    Ministry of Health Decree 136/1951 (XII.18.) regulated the operation of medical committees issuing opinions in respect of decreased work capacity. One first instance medical committee was set up in medical centres in rural regions. In Budapest, a higher number of first instance medical committees were set up in relation to needs. At least two surgery, two internal medicine and one neurology first instance medical committee was set. The same decree also stipulated the organisation of second instance medical committees.

1952    Medical committees were set up in January.

1957    A senior medical consultant appointed centrally managed the work of the medical committees and oversaw their operation in Budapest. This individual was equally responsible for the professional and administrative management of medical committees operating in the counties, supervising these committees and organising trainings for consultants on these committees. The senior medical consultant reported to the Ministry of Health since the minister was competent for appointing this individual. Determining diseases was the predominant activity within the framework of the medical expert work process in this particular era.

1960    Ministry of Health Decree 44/1960 (MH. 24.) set up the Budapest-based National Directorate for Medical Committees Assessing Decreased Work Capacity. Besides this unit, the decree also stipulated setting up second instance medical committees in Debrecen, Pécs, Szeged and Győr. The national directorate was morally and professionally acknowledged by the medical profession and patients alike.

1963    The handbook “Extracts for Determining Decreased Work Capacity” edited by Dr Jenő Írás National Chief Medical Director was published. A standard committee practice was established for determining diseases based on the guidelines set out in the handbook.  

1967    Ministry of Health Decree 1/1967 (MH. 1.) delegated second instance medical opinion on occupational fitness, as well as the review of the earning capacity of the insured individual determined to be in earning capacity during the course of medical review by the medical decision-making committee to the scope of competency of the Directorate. This decree equally stipulated the compulsory professional division and other administrative requirements in committees. 

1971    Pursuant to Ministry of Health Decree 45/1970 (MH. 24.), the National Directorate for Medical Committees Assessing Decreased Work Capacity continued to operate as the National Medical Expert Institute. This institute was the core institution for treatment and prevention, organisational methodology, training and scientific research of the Ministry of Health in regard to conducting medical examinations and issuing opinions in connection with work and earning capacity, job fitness, disability and decreased work capacity.

2008    Pursuant to Act LXXXIV of 2007, the rehabilitation benefit and complex changed work capacity assessment procedure was introduced on 1 January 2008. This new procedure focused on mapping the preserved state of health and abilities that can be developed and evaluating rehabilitation chances. As of 1 January 2008, ORSZI acts as an autonomous social expert body independent to service providers in the case assessing caring needs preceding the use of home care and home care assisted with a medical alert system.

2009    Pursuant to Government Decree 92/2008 (IV. 23.), ORSZI undertakes disability eligibility, social employment eligibility and comprehensive rehabilitation eligibility assessments as of 1 July 2009. 

2010    Pursuant to the amendment of Act III of 1993, the assessment of caring needs was removed from the scope of competency of ORSZI on 17 August 2010.

2011    In accordance with Government Decree 331/2010 (XII. 27.), the name of the National Rehabilitation and Social Institute was changed to the National Office for Rehabilitation and Social Affairs (NORSA). Pursuant to this decree, the scope of tasks and competency of this office was significantly extended. As of 1 January 2011, this office operates as a medical expert and rehabilitation expert body, as well as a social authority and authority supervising services. 

2012    By introducing the disability and rehabilitation benefit on 1 January, the benefit scheme that became far too complicated over the decades was considerably simplified. Ministry of National Resources Decree 7/2012 (II. 14.) defines the set of professional rules to be applied in respect of the complex assessment procedure. Regulations relating to the list of employment rehabilitation experts and rehabilitation medical experts were also published.

By setting up these units, the processing of claims, accreditation of experts and promoting the implementation of employment rehabilitation was integrated into a single organisation.
