In Russia, the study of the structure of morbidity began from the period of zemstvo medicine, and the first classification of diseases appeared already in 1876. At the VII Pirogov Congress of Doctors, the first domestic nomenclature of diseases was adopted. At the beginning of the 20th century, the International Classification of Diseases was created, and currently its 10th revision is in effect in all countries of the world. ICD-10 was adopted by the 43rd World Health Assembly in Geneva (1989) and recommended for use in Russian Federation since 1993.
The main innovation in ICD-10 compared to ICD-9 is the use of an alphanumeric coding system with four-digit categories consisting of one letter of the Latin alphabet followed by three digits (for example, A00.0-A99.9). This system makes it possible to more than double the volume of encoded information. The introduction of letters into the rubrics made it possible to code up to 100 three-digit categories in each class. Some three-character headings are left free, which will allow them to be expanded and revised in the future. The number of such free categories in different classes not the same.
ICD-10 includes 21 classes of diseases and 4 additional sections.

ICD-10 is an abbreviation for the list of international classification of diseases, which underwent the next, tenth revision in 2010. This classification contains codes that designate all diseases known to medicine.

Very often, the diagnosis given to the patient is quite cumbersome, as it contains a whole set of concomitant ailments. For the convenience of its description, ICD-10 is used. Instead of the name of the disease, the corresponding code is entered into the patient’s card, medical history, and most importantly, the documents of the Health Insurance Fund.

What else is microbial 10 ( international classification diseases), what basic disease codes are provided? Let's talk about this in more detail on this page www.site:

Why is ICD-10 needed?

To provide a modern, normal level health care, actively develop medical science, it is necessary to regularly update data on the state of health of the population, have information about the activities of hospitals, clinics, and other health care institutions. For this it is necessary to develop Information Systems, increase their reliability and efficiency. The creation of such systems is impossible without using a code classification of diseases.

This classification is provided by one of the main statistical classification frameworks - the International Classification of Diseases (ICD). It also contains a list of injuries and causes of death. Medical science does not stand still and is actively developing. Therefore, under the leadership of WHO, this system is revised once every 10 years.

Thus, the ICD is a single regulatory document that ensures uniformity and comparability of international methodological approaches and materials to a specific disease.

With the latest, tenth revision of this regulatory document, in addition to the usual, traditional structure of the ICD, an alphanumeric system of certain codes was compiled, which replaced the outdated digital one. The introduction of a new coding seriously expands the capabilities of modern classification. In addition, alphanumeric encoding does not disrupt the digital system during the next revision, which has often happened in the past.

ICD-10 is compiled more optimally than previous classifications. In particular, it expands the grouping of diseases of the eye, ear, as well as the adnexal apparatus and mastoid process. ICD-10 includes some blood diseases in the classification “Diseases of the blood and hematopoietic organs”. Besides, external factors, influencing the state of human health are included in the main part of the main classification. Previously they were included in additional parts.

This tenth classification was fully approved by the International Conference on the next revision of the ICD and adopted at the Forty-third World Health Assembly.

The document contains everything normative definitions and an alphabetical list of known diseases. Includes: three-digit headings, four-digit sub-headings containing the necessary notes, lists of exceptions for the main disease, as well as statistics, rules for determining the main causes of death of patients. There is also a list of reasons for the necessary hospitalization of patients.

A detailed list of headings has been compiled, including short lists that help in developing data on morbidity, attendance at health care facilities, and mortality. Available guidelines filling out perinatal mortality certificates.

Before practical use of ICD-10, it is necessary to carefully study the structure of the classification, carefully familiarize yourself with the presented groupings of painful conditions, study notes, inclusions, exclusions, selection rules, and coding of the main diagnosis.

ICD-10 classes

The document consists of 21 sections. Each section includes subsections with codes for known diseases and pathological conditions. The classification is presented as follows:

As an example, how condition codes are encrypted in ICD 10, Here's a breakdown of grade 15.

O00-O08. Gestation with abortion
O10-O16. Proteinuria, edema and blood pressure disorders during pregnancy, during and after childbirth
O20-O29. Other maternal diseases associated with pregnancy
O30-O48. Assistance from doctors to the mother in connection with indicators of the condition of the fetus and possible difficulties of delivery
O60-O75. Difficulties with childbirth
O80-O84. Singleton birth, spontaneous birth
O85-O92. Difficulties, mainly with the period after childbirth
O95-O99. Other obstetric conditions not meeting other criteria

In turn, state intervals have a more specific interpretation. I'll bring you example for codes O00-O08:

O00. Pregnancy outside the uterus (ectopic)
O01. Cystic skid
O02. Other abnormal conception defects
O03. Spontaneous abortion
O04. Medical abortion
O05. Other methods of abortion
O06. Unspecified abortion
O07. Abortion attempt unsuccessful
O08. Difficulties due to abortion, molar or ectopic pregnancy

There are also further clarifications in ICD-10. I'll bring you example for code O01 Bubble skid classic:

O01.0 Classic bubble skid
O01.1 Hydatidiform mole, partial and incomplete
O01.9 Unspecified hydatidiform skid

Important!

If you study the official list of ICD-10, you will see that the alphabetical index of diseases at the beginning of the diagnostic slots also contains unspecified conditions indicated by the signs 9, NOS, NCD. Here is the example above “O01.9 Unspecified vesicular skid”. It is recommended to use such encodings in extreme cases, but generally not advisable, since they are not informative for statistics. The doctor should seek clarification of the diagnosis, which corresponds to a certain classification.

For more accurate information on disease codes, use the official ICD-10 document! The codes given here are accurate enough to convey the spirit of the document, but not quite precise in the wording, which our popular presentation format allows.

List of ICD-10 classes

ICD-10- International Classification of Diseases, 10th revision. As of January 2007, it is a generally accepted classification for coding medical diagnoses, developed by the World Health Organization. ICD-10 consists of 21 sections, each of which contains subsections with codes for diseases and conditions.

It was created to unify the process of coding diseases and pathological conditions. As a result, doctors from all over the world are now able to exchange information, even without speaking many languages.

History of the creation of the ICD

The ICD is a classification, the basis of which was laid back in 1893 by Jacques Bertillon, who at that time held the position of head of the Paris Bureau of Statistics. On behalf of the International Statistical Institute, he developed a classification of causes of death. In his work he built on earlier Swiss, French and English works.

Jacques Bertillon's classification of causes of death was generally accepted and widely used in Europe and North America. During the 6th revision in 1948, its structure also included diseases and pathological conditions that do not lead to death.

The modern ICD is a document of the 10th revision, approved by the World Health Assembly in 1990. In fact, practicing doctors began to use it in 1994. In the Russian Federation, the official use of ICD-10 began only in 1997.

Since 2012, scientists have been developing ICD-11, but to date this document has not entered into force.

Features of the structure and basic principles of ICD-10

The 10th version of the international classification of diseases introduced fundamental changes to its structure, the main of which was the use of an alphanumeric coding system.

The ICD-10 classification has 22 classes, which are grouped into the following groups:

• epidemic diseases;
• general or constitutional diseases;
• local diseases, which are grouped according to anatomical characteristics;
• developmental diseases;
• traumatic injuries.

Some classes include several letter headings at once. The 11th revision of this document is currently underway, but no significant changes are planned in the classification structure.

Composition of the ICD

This international classification consists of three volumes at once:

• the first volume includes a basic classification, special lists for summary statistical developments, a section dedicated to the “Morphology of Neoplasms,” as well as nomenclature rules;
• the second volume contains clear instructions on how to correctly use ICD-10;
• the third volume includes an alphabetical index accompanying the main classification.

Today, these 3 volumes are most often combined and published under 1 cover for user convenience.

Letter rubrics

ICD-10 is an international classification of diseases, and therefore its creators had to come up with unified designations that are understandable to every specialist. For this purpose, it was decided to use headings designated in Latin letters. There are 26 of them in total. At the same time, the creators left the U section for further development ICD-10.

The disease codes in this document, in addition to the letter designation, also include a number. It can be two or three digits. Thanks to this, the creators of the ICD were able to encode all known diseases.

Practical use of ICD-10

Deciphering this coding system using the appropriate reference book is absolutely no difficulty not only for medical specialists, but also for people who do not have any medical knowledge. Doctors use ICD on an ongoing basis. Any disease that occurs in their patients is coded according to the international classification. Most often in practice, doctors use them for:

1. Issuance of medical documents, if necessary, to hide the diagnosis (usually when a person passes a commission to get a job, receives a document confirming that the patient actually saw a doctor).
2. Filling out medical documentation (extract from medical history, inpatient card).
3. Filling out statistical reporting documents.

As a result, ICD-10 allows not only the exchange of information between doctors in different countries, but also the preservation of medical confidentiality.

Coding by class

ICD-10 consists of 22 classes. Each of them includes diseases that have general principles pathogenesis or related to a specific anatomical region. All classes have their own designation in the form Latin numerals. Among them:

As for class 22, it is reserved for that group of diseases or pathological conditions that have not yet been established.

Further development paths

ICD-10 is an international classification of diseases that has serious potential for development. Currently, doctors use this document not only in paper form, but also in electronic form. For these purposes, a huge number of thematic websites have been created, and several mobile applications have been developed.

Also, coding according to ICD-10 is included in all electronic systems medical integration, which are currently very actively developing in the countries of the post-Soviet space. Taking into account the availability of the free category U, this classification may in the future include a whole class of new diseases.
