Cervical conization (
ICD-9 code 67.2,
CPT codes 57520(Cold Knife) and 57522(Loop Excision)) refers to a
biopsy of the
cervix in which a cone-shaped sample of tissue is removed from the
mucous membrane. Conization may be used either for diagnostic purposes, or for therapeutic purposes to remove pre-cancerous cells.
Conization of the cervix is a common treatment for dysplasia following abnormal results from a pap smear.
