Summary & Overview
CPT 57520: Conization of Cervix with Scalpel or Laser
CPT code 57520 represents conization of the cervix — a gynecologic surgical procedure performed with a scalpel or laser, often with fulguration, and sometimes including dilation and curettage or repair. Nationally, this code is used to treat or evaluate cervical dysplasia and early cervical pathology, making it clinically significant for women’s health services and surgical oncology pathways. Payers frequently review utilization, site-of-service selection, and bundling with related procedures when addressing coverage and payment.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context, typical settings of care, and the major billing considerations associated with CPT code 57520. The publication outlines benchmarks and common modifier usage patterns where available, plus policy and reimbursement considerations that affect facility and professional claims. It also highlights areas where coding specificity and documentation are important for correct claim adjudication.
The report is written for a national audience and is intended to inform billing professionals, clinicians, and policy analysts about the scope and implications of CPT code 57520, including operational and payer-facing issues. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 34-year-old patient with an abnormal cervical cytology (high-grade squamous intraepithelial lesion) and positive high-risk HPV undergoes a diagnostic and therapeutic cervical conization. The patient presents to an ambulatory surgical center after counseling and informed consent. Preoperative workup includes pregnancy test, coagulation review, and review of prior biopsies. Under monitored anesthesia care or general anesthesia, the gynecologic surgeon performs a cold-knife or laser conization of the cervix with possible fulguration of the transformation zone. The procedure may include cervical dilation, endocervical curettage, and hemostatic measures; tissue is sent to pathology. Postoperative instructions include activity restrictions, signs of hemorrhage or infection, and follow-up for pathology review and possible repeat cytology/HPV testing. Typical sites of service are outpatient ambulatory surgical centers or hospital outpatient departments; anesthesia may be local with sedation, monitored anesthesia care, or general anesthesia depending on clinical factors.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typical for the conization (e.g., extensive lysis of adhesions, difficult anatomy). |
