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.

About the D37 Code Range
These growths have uncertain behavior and occur in the lip, mouth, throat, or digestive organs. The subdivisions distinguish them by site.
D37.0 groups the lip, oral cavity, and pharynx. Its subdivisions separate the lip, tongue, salivary glands, pharynx, and other specified oral cavity sites. The major salivary gland codes distinguish the parotid, sublingual, and submandibular glands, or leave the gland unspecified.
Other subdivisions identify the stomach, small intestine, appendix, colon, rectum, or liver, gallbladder, and bile ducts. They also distinguish other specified digestive organs from an unspecified digestive organ.
