To begin with, note that ICD-10 is an international classification of diseases. In particular, it defines a system of headings, including individual pathological states according to certain established criteria.
At present, ICD-10 states are grouped together to ensure its maximum acceptability during use for general epidemiological purposes. In addition, states are combined to assess the quality of health care.
Gastritis for ICD-10
Duodenitis and gastritis in this classification is under the diagnosis code 29 or simply K29.Here are the main diagnosis codes for most types of gastritis in ICD-10:
- ICD-10 code 29.0 - Acute hemorrhagic;
- K29.1 - Other types of gastritis( acute);
- K29.2 - Alcoholic;
- K29.3 - Superficial chronic;
- K29.4 - Chronic atrophic( there is atrophy of the gastric mucosa);
- K29.5 - Unspecified chronic( base, antral);
- K29.6 - Other chronic types( hypertonic, granulomatous giant, Menetria disease);
- K29.7 - Unspecified gastritis;
- K29.8 - Duodenitis;
- K29.9 - Unspecified gastroduodenitis.
In addition to ICD-10, several other classifications of gastritis can be distinguished. Consider the two most modern of them.
Sydney classification of gastritis
It was created in 1990 with the participation of gastroenterologists, pathologists, microbiologists, histopathologists and immunologists. Sydney classification, itself is divided into two sections:
- Histological .It consists of aetiolgia, morphology and topography. On etiology different forms of protracted gastritis, such as autoimmune, Helicobacter, reactive and special forms of the disease, differ. On the typography of the inflammatory process in the stomach itself, such species as pangastritis, disease of the body of the stomach and antrum are isolated. As for the morphological part of the diagnosis, it can be said that it is always associated with specific parts of the stomach. There are three main types of morphological changes, which include chronic, acute gastritis, as well as specific forms of the disease.
- Endoscopic .This section is characterized by edema and marked hyperemia of the gastric mucosa. In addition, there are erosions and hemorrhages, hyperplasia of the folds.
Classification of gastritis OLGA
This is a completely new system that was proposed by a group of experts from well-known pathologists and several gastroenterologists and clinicians in 2008.In the classification of gastritis OLGA, the evaluation of the histological severity of the necrosis of the mucosa, inflammation in the body of the stomach, and also in the antrum with further determination of the stage and degree of chronic gastritis is used.
Note that in the OLGA system there are two big advantages:
- determination of the stage of atrophy, allowing to objectively determine the presence and severity of the spread of the degree of inflammation;
- determination of the stage of atrophy based on the results of treatment.
