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.

Hemorrhoids
Swollen veins in the lower part of the RECTUM or ANUS. Hemorrhoids can be inside the anus (internal), under the skin around the anus (external), or protruding from inside to outside of the anus. People with hemorrhoids may or may not exhibit symptoms which include bleeding, itching, and pain.
About the K64 Code Range
Hemorrhoids appear alongside perianal venous thrombosis, a blood clot in a vein around the anus. Piles is another name for hemorrhoids.
Within K64, subdivisions distinguish first through fourth degree hemorrhoids: K64.0, K64.1, K64.2, and K64.3. Separate subdivisions identify residual hemorrhoidal skin tags (K64.4), perianal venous thrombosis (K64.5), other hemorrhoids (K64.8), and unspecified hemorrhoids (K64.9).
