Cervical conization (CPT codes 57520 (Cold Knife) and 57522 (Loop Excision)) refers to an excision of a cone-shaped sample of tissue from the mucous membrane of the cervix. Conization may be used either for diagnostic purposes as part of a biopsy, or for therapeutic purposes to remove pre-cancerous cells.[1]

Types include:

Conization of the cervix is a common treatment for dysplasia following abnormal results from a pap smear.

Side effects

Cervical conization causes a risk for subsequent pregnancies ending up in preterm birth of approximately 30% on average, due to cervical incompetence.[3]
