Limerick East): Under the Health Act, 1970, medical cards are issued to persons who, in the opinion of the chief executive officer of the appropriate health board, are unable, without undue hardship to provide general practitioner medical and surgical services for themselves and their dependants. Income guidelines are available to assist chief executive officers in the determination of a person's eligibility and these guidelines are revised annually in line with the consumer price index. However, these guidelines are not statutorily binding and even though a person's income exceeds the guidelines, that person may still be awarded a medical card if the chief executive officer considers that the person's medical needs or other circumstances would justify this.
