ICD or International Classification of Diseases is an WHO-based classification system, which provides a detailed list of diagnostic codes for the classification of different diseases. The aim of this classification is to ably and accurately calculate life expectancy and mortality statistics on a worldwide basis. It also helps in underlining the effectiveness of healthcare support systems of various governments on a global scale. The project is sponsored by the UN and includes a detailed classification of symptoms, social circumstances, abnormalities, and causes of diseases.
ICD 9 was the ninth revision of the code, which was decided in a conference that met in October 1975. Since then, the ninth version has been in force until ICD 10 took place in 1992. Though it was decided that there should not be much change in the codes, ICD 9 did succeed in adding a lot of details while retaining the same structure for diagnosis codes.
The ICD 9 code for cerebrovascular accident, or stroke as it is more commonly called, is 434.91. In exact terms, it is described as Cerebral artery occlusion unspecified with cerebral infarction . A stroke is caused by lack of oxygen supply to the brain. When the blood flow to the brain is cut off due to damaged blood vessels or a clot, then the vital nutrients and oxygen carried by the blood to the brain is no longer in supply. This leads to the damage of brain cells and tissue and is called a stroke, or a cerebrovascular accident.
A stroke is a medical emergency and the patient must be immediately conveyed to a hospital. The sooner the treatment is given, the better the chances of a recovery. Failure to treat a stroke soon can lead to permanent brain damage, paralysis, and even death.
Different drugs are used to treat a stroke. Doctors usually make use of an anticoagulant to dissolve the blood clot in the brain. The patient is also given oxygen, so that the brain can revive under its influence. Medicines for controlling blood pressure and glucose levels are given. If the case is serious with blockage that cannot be treated by medication, doctors also perform surgery to remove this blockage and allow free blood circulation to the brain. Surgery might also be required to remove the excess blood in case of a ruptured blood vessel.
Post-operative treatment is very important for patients who have suffered from a cerebrovascular accident. This therapy is very important to get the patient back to functioning to their full potential. This includes speech therapy, physical therapy, and consultations with psychiatrists and neurologists.
Symptoms of a stroke are often very pronounced and clear. A patient is no longer fully functional after a stroke. Sudden weakness or numbness of one side of the body is a main symptom of a major stroke. Other symptoms include difficulty in walking, confusion, garbled speech, loss of eye coordination, severe headache, dizziness, and fainting spells. If any of these symptoms occur, it is important to immediately consult emergency medical services for a quick diagnosis or treatment. Take a stroke very seriously, it might save a life!
