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 R22 Code Range
These codes describe swelling, a mass, or a lump in a particular area of the skin or the tissue beneath it.
R22 is organized by location: the head, neck, trunk, upper limb, or lower limb. The upper- and lower-limb subdivisions distinguish an unspecified limb, the right limb, the left limb, and both limbs. R22.9 leaves the location unspecified.
