ACVA ICD 10 code is a classification on the basis of which the most accurate diagnosis is made, indicating the specific area of cerebrovascular accident. This scale is accepted all over the world and helps the patient to seek help with a ready-made diagnosis in a clinic in any other country. In this case, the doctor at the foreign medical center will fully understand the previously made diagnosis and quickly select the necessary therapy.
In this scale, there are 10 types of diseases with codes from I 60 to I 69. Let's consider each type separately.
I60 Subarachnoid hemorrhage
Includes: rupture of cerebral aneurysm
Excludes: consequences of subarachnoid hemorrhage (I69.0)
I60.0 Subarachnoid hemorrhage from the carotid sinus and bifurcation
I60.1 Subarachnoid hemorrhage from the middle cerebral artery
I60.2 Subarachnoid hemorrhage from the anterior communicating artery
I60.3 Subarachnoid hemorrhage from the posterior communicating artery
I60.4 Subarachnoid hemorrhage from the basilar artery
I60.5 Subarachnoid hemorrhage from the vertebral artery
I60.6 Subarachnoid hemorrhage from other intracranial arteries
I60.7 Subarachnoid hemorrhage from intracranial artery, unspecified
I60.8 Other subarachnoid hemorrhage
I60.9 Subarachnoid hemorrhage, unspecified
Strokes
The definition of “stroke” means a violation of the integrity of the arterial wall with blood entering nearby tissues. This disease has serious consequences - disruption of the neural network in the cortex due to hematoma, which leads to loss of physical and cognitive abilities.
In the ICD 10 scale, strokes occupy 3 gradations.
- I 60 is a subarachnoid hemorrhage when a vessel ruptures between the arachnoid and pia mater. This code has 5 subtypes of the disease, which are determined by the location of the damaged artery. Additional encoding is indicated using a dot.
- I 61 – parenchymal (intracerebral) hemorrhage. A rupture of a blood vessel in the inner region of the brain, where the gray and white matter is located. This code also contains 5 additional subtypes that define a specific break area.
- I 62 – the location of the hemorrhage is unknown. The doctor identified the fact of a stroke, but the specific area of damage was not found. This code has 3 additional subtypes.
The consequences of the hemorrhagic type of stroke are included in the headings of the ICD 10 scale. These deviations develop against the background of a stroke and can cause lifelong disability for the patient. Such pathologies need to be treated urgently in order to exclude a very likely fatal outcome (about 30% of patients die within five years due to subsequent complications).

I63 Cerebral infarction
Includes: occlusion and stenosis of the cerebral and precerebral arteries causing cerebral infarction
Excludes: complications after cerebral infarction (I69.3)
I63.0 Cerebral infarction caused by thrombosis of precerebral arteries
I63.1 Cerebral infarction caused by embolism of precerebral arteries
I63.2 Cerebral infarction caused by unspecified occlusion or stenosis of precerebral arteries

I63.8 Other cerebral infarction
I63.9 Cerebral infarction, unspecified
Remaining classification
Above is a key classification of problems with blood flow in the brain, which reflects the most commonly diagnosed conditions. Let's consider what other cases, diseases and complications of stroke there are, which are covered by separate codes on the ICD 10 scale:
- I 64 – placed if the clinical picture is unclear and the patient has symptoms of both an ischemic attack and hemorrhage.
- I 67 – the disease is associated with impaired blood circulation in the brain, but is neither a heart attack nor a stroke.
- I 68 – disturbance of blood flow in the brain as a consequence of another disease.
- I 69 – complications after cerebrovascular accident.

PSYCHIATRIC
ICD-10 Preface.
In the early 1960s, the World Health Organization began active work on a program aimed at improving the diagnosis and classification of mental disorders.
At that time, WHO held a series of meetings at which representatives of various disciplines and schools of psychiatry from around the world summarized the then existing knowledge in this area. WHO stimulated and conducted research into classification criteria and diagnostic reproducibility. In addition, procedures for joint diagnostic assessments of clinical material based on the study of videotaped interviews with patients and other methods were developed and disseminated. As a result of numerous proposals to improve the classification of mental disorders, the 8th revision of the International Classification of Disease (ICD-8) was carried out during the widest consultations. A special glossary has been developed to define each category of mental disorder in ICD-8. Work on the above program also led to the creation of a team of individuals and a network of national centers dealing with the problems of improving psychiatric classification. The 1970s saw increased interest in improving psychiatric taxonomy throughout the world. This was facilitated by the expansion of international contacts, the organization of several international collaborative studies and the emergence of the possibility of new forms of therapy. The development of specific classification criteria has been encouraged in a number of countries to improve diagnostic reproducibility. In particular, the American Psychiatric Association developed and disseminated the 3rd revision of the Diagnostic and Statistical Manual, which included the use of operational criteria in its classification system.
In 1978, WHO entered into a long-term project with the US Administration on Alcohol and Drug Abuse to further improve the classification and diagnosis of mental disorders and alcohol and drug use problems. In a series of workshops that brought together scientists from different psychiatric traditions, knowledge in their respective fields was reviewed and recommendations for further research were developed. These recommendations were summarized at a major international conference in Copenhagen, Denmark in 1982.
Several major studies have been undertaken to implement the recommendations of the Copenhagen Conference. One of them, which involved centers in 17 countries, aimed to develop the Composite International Diagnostic Interview, an instrument that would be suitable for conducting epidemiological studies of mental disorders in general populations in different countries. Another major project focused on developing an assessment tool suitable for use by clinicians. Another study was devoted to the development of an instrument to assess personality disorders in different countries.
In addition, several more dictionaries with clear definitions of terms have been prepared and are being prepared. Work on these projects was fruitfully associated with the development of definitions of mental and behavioral disorders in the International Statistical Classification of Diseases and Related Health Problems (ICD-10). The translation of diagnostic criteria into diagnostic algorithms included in assessment tools has proven useful in identifying inconsistencies, points of contention, and repetition that can be eliminated. On the other hand, work on ICD-10 has helped in the development of assessment tools. The final result was the creation of a clear system of ICD-10 criteria and assessment tools that can provide the data needed to classify disorders according to the criteria included in Chapter V(F) of ICD-10.
The Copenhagen Conference also recommended that the positions of the various schools of psychiatry be presented in publications on the sources of the ICD-10 classification. As a result, several major publications appeared.
The first book among the publications compiled on the basis of Chapter V (F) of ICD-10 was the glossary “Clinical Descriptions and Diagnostic Guidelines”. It represents the culmination of the efforts of many people who have worked on it over a number of years. In the course of this work, several large projects were prepared, each of which came out after numerous consultations with groups of experts, national and international psychiatric associations and individual consultants. The 1987 project led to trials at 40 national centers, an unprecedented study of its kind aimed at improving psychiatric diagnosis. The results of these trials were used to prepare the final clinical guidelines.
The text presented in this book has also been widely reviewed. Researchers and clinicians from 32 countries participated. Subsequent publications will include a version for general practitioners, a multi-axis version of the classification, a series of publications detailing more specific problems (for example, on the assessment and classification of mental retardation), as well as reference materials allowing comparison of relevant terms in ICD-10, ICD-10 9 and ICD-8.
With the accumulation of experience and the expansion of our knowledge, it should be possible to further improve the classification of mental disorders. This task will be assigned primarily to those WHO centers that participated in the preparation of this classification.
There are numerous publications from national centers based on and related to ICD-10 research. A complete list of these and reprints of the articles can be obtained on request from the Department of Mental Health, WHO, 1211 Geneva 27, Switzerland.
Classification is a way of seeing the world at a certain time stage. Without a doubt, scientific progress and experience with the present research criteria will require their revision and updating. I hope that such a revision will be the result of the same cordial and productive international scientific cooperation as in the preparation of this classification.
