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.

Definitions from the National Library of Medicine for conditions coded in the J33 range.

Nasal Cavity Polyp

A soft and painless polypoid mass that arises from the mucosa in the nasal cavity. It is usually the result of an inflammatory process. It may recur following surgical resection.

Nasal Polyps

Focal accumulations of EDEMA fluid in the NASAL MUCOSA accompanied by HYPERPLASIA of the associated submucosal connective tissue. Polyps may be NEOPLASMS, foci of INFLAMMATION, degenerative lesions, or malformations.

Polypoid Sinus Degeneration

Recurrent nasal polyps with subsequent destruction of the nasal pyramid.

The subdivisions distinguish a polyp of the nasal cavity (J33.0), polypoid sinus degeneration (J33.1), and other sinus polyps (J33.8). J33.9 identifies a nasal polyp without further detail.
