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.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the K25 range.
Stomach Ulcer
Ulceration of the GASTRIC MUCOSA due to contact with GASTRIC JUICE. It is often associated with HELICOBACTER PYLORI infection or consumption of nonsteroidal anti-inflammatory drugs (NSAIDS).
About the K25 Code Range
A gastric ulcer is a sore in the stomach lining caused by contact with stomach juice. These codes sit within diseases of the stomach and nearby digestive organs.
The subdivisions separate acute ulcers from chronic ulcers and ulcers not specified as acute or chronic. For acute ulcers, they distinguish bleeding, perforation, both, or neither. Chronic or unspecified ulcers also have separate codes for bleeding, perforation, or both. Without either complication, K25.7 identifies a chronic ulcer, while K25.9 identifies an ulcer not specified as acute or chronic.
