Cyst (mucus) (retention) (serous) (simple)
Note In general, cysts are not neoplastic and are classified to the appropriate category for disease of the specified anatomical site. This generalization does not apply to certain types of cysts which are neoplastic in nature, for example, dermoid, nor does it apply to cysts of certain structures, for example, branchial cleft, which are classified as developmental anomalies. The following listing includes some of the most frequently reported sites of cysts as well as qualifiers which indicate the type of cyst. The latter qualifiers usually are not repeated under the anatomical sites. Since the code assignment for a given site may vary depending upon the type of cyst, the coder should refer to the listings under the specified type of cyst before consideration is given to the site.
