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 R19 range.
Diarrhea
An increased liquidity or decreased consistency of FECES, such as running stool. Fecal consistency is related to the ratio of water-holding capacity of insoluble solids to total water, rather than the amount of water present. Diarrhea is not hyperdefecation or increased fecal weight.
Halitosis
An offensive, foul breath odor resulting from a variety of causes such as poor oral hygiene, dental or oral infections, or the ingestion of certain foods.
About the R19 Code Range
Swelling or a lump in the abdomen or pelvis, unusual bowel sounds, a rigid abdomen, and changes in bowel habits appear here alongside other digestive symptoms.
R19.0 groups swelling and lumps by location, while R19.3 groups abdominal rigidity by location. Both distinguish right and left upper and lower areas, areas around the navel, and the upper middle abdomen. R19.1 separates absent, hyperactive, and other abnormal bowel sounds. The remaining subdivisions describe visible movement in the abdomen, changed bowel habits, stool abnormalities, bad breath, unspecified diarrhea, and other specified symptoms.
