Gastric ulcer (K25)
ICD-10 code K25 covers various forms of gastric ulcers, which are sores developing on the stomach lining. These codes help classify ulcers by their severity; acute or chronic; and by complications such as bleeding (hemorrhage), hole formation (perforation), or both.
This section includes specific codes from K25.0 to K25.9 that allow precise identification of different ulcer types. For example, K25.0 is used for acute gastric ulcers with hemorrhage, often called "gastric ulcer with hemorrhage" or "acute gastric ulcer with obstruction," while K25.1 represents ulcers with perforation, synonymous with "acute gastric ulcer with perforation." Codes like K25.3 cover acute ulcers without bleeding or perforation and include conditions such as Helicobacter pylori-induced ulcers or stress ulcers. Chronic ulcers with similar complications are classified from K25.4 through K25.7. The unspecified type, K25.9, is reserved for ulcers where acute or chronic status and complications aren’t detailed. Understanding these synonyms and distinctions helps medical coders accurately assign the appropriate ICD-10 code for gastric ulcers in clinical documentation and billing.

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
