CPT Code 57460 Endoscopy Procedures on the Cervix Uteri

Accurate CPT coding remains a cornerstone of compliance and revenue optimization for OBGYN practices. CPT 57460 refers to a colposcopy of the cervix and upper/adjacent vagina performed with a loop electrode biopsy, typically as part of the evaluation and management of abnormal cervical cytology. This procedure combines diagnostic visualization with a therapeutic biopsy using a loop electrosurgical excision technique (LEEP or LLETZ).

This guide explains the correct usage, documentation standards, modifier application, and reimbursement considerations, as per the CMS and AAPC 2025 updates, to support accurate OBGYN billing and audit readiness.

CPT 57460 – Description

Official Definition: “Colposcopy of the cervix, including upper/adjacent vagina; with loop electrode biopsy(s) of the cervix.”

This code covers both the magnified visual assessment of the cervix and adjacent vaginal tissue and the removal of cervical tissue using a loop electrosurgical device. It is typically performed when prior cytology or HPV screening suggests moderate to severe dysplasia.

Key distinctions:

• 57460 includes colposcopy with loop biopsy (LEEP/LLETZ).
• 57454 covers colposcopy with biopsy and/or ECC (without loop excision).
• 57522 applies to conization or excision of a cone-shaped specimen (more extensive than 57460).

When to Use CPT 57460

Use CPT 57460 when a provider performs a colposcopic evaluation followed by excision of abnormal cervical tissue with a loop electrode. Common clinical indications include:

• High-grade squamous intraepithelial lesion (HSIL) on Pap smear.
• Cervical intraepithelial neoplasia (CIN 2 or CIN 3).
• Persistent abnormal cytology after previous treatments.
• HPV-related cervical dysplasia requiring excision.
• Visualization of the abnormal transformation zone during colposcopy.

Do not report 57460 for:

• Diagnostic colposcopy without excision (use 57452 or 57454).
• Conization procedures extending into the endocervical canal (use 57522).
• Destruction of lesions without biopsy (use 57511–57513).

Coding and Billing Guidelines

According to the CMS 2025 Physician Fee Schedule and AAPC guidance:

• Report 57460 once per surgical session, regardless of the number of excision passes.
• Do not separately bill for ECC or biopsy if performed during the same loop excision; these are included in 57460.
• The code has a 10-day global period; routine post-procedure visits are bundled.
• Ensure documentation of medical necessity based on cytology, HPV results, or visual findings.
• Apply modifiers only when distinct, unrelated services are performed during the same encounter.

Reimbursement Overview

CPT 57460 – 2025 Payment Data

• Global period: 10 days
• Typical setting: Office or outpatient surgical suite
• Average Medicare payment: $180–$210 (regional variation applies)
• ASC payment: Often included under bundled gynecologic procedure codes

Payers may request pathology confirmation or documentation showing abnormal findings that justified the excision. Prior authorization may be required for certain commercial plans when LEEP is performed in-office.

Modifier Guidance

Use modifiers accurately to represent the scope and context of services:

• Modifier 25: For a separately identifiable E/M service on the same date.
• Modifier 51: When multiple procedures are performed during the same session.
• Modifier 59 (or XU): If another unrelated procedure was performed at a distinct anatomical site.
• Modifier 26 / TC: To differentiate professional and technical components for hospital-based billing.

Avoid redundant modifier use, as it may trigger payer reviews or claim denials.

Documentation Standards

Detailed and accurate operative documentation is vital for compliance and payment accuracy. The provider’s notes should include:

• Clinical reason for the procedure (CIN 2/3, HSIL, HPV-positive results).
• Colposcopic findings and visualization of the transformation zone.
• Description of the loop electrode technique and tissue removal.
• Size, location, and appearance of the excised specimen.
• Confirmation that specimens were submitted for pathology.
• Post-procedure care instructions and follow-up plan.

Comprehensive notes support the medical necessity and protect against payer audits under the 2025 CMS standards.

Example Scenarios

Scenario 1:

A patient with an HSIL Pap result undergoes colposcopy, and the provider performs a loop electrode biopsy to excise a dysplastic lesion from the cervix. → Report CPT 57460.

Scenario 2:

A colposcopy with both ECC and biopsy (without loop excision) is performed. → Use CPT 57454.

Scenario 3:

A larger conization extending into the endocervical canal is performed using a loop electrode. → Report CPT 57522, not 57460.
