Cervical conization

Overview
Cervical conization (ICD-9 code 67.2, CPT codes 57520 and 57522) 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 and human papillomavirus (HPV) following abnormal results from a pap smear.
