CPT Code 57455 is the correct CPT code for colposcopy with biopsy of the cervix and/or endocervical curettage (ECC) performed under anesthesia. If a cervical biopsy is completed during colposcopy, CPT 57455 should be reported instead of a diagnostic colposcopy code without biopsy.

Avoid one of the most common OB/GYN billing mistakes: reporting the wrong colposcopy CPT code can result in claim denials, reduced reimbursement, and compliance issues. Here’s how to bill 57455 CPT code correctly the first time.

1) What Is CPT Code 57455?

CPT Code 57455 Description: Colposcopy of the cervix with cervical biopsy and/or endocervical curettage (ECC) performed under anesthesia.

This 57455 CPT code description applies when a physician performs a colposcopy with biopsy under anesthesia. Tissue is collected for pathology evaluation, and endocervical curettage (ECC) may also be performed during the same session.

This is one of the most frequently used CPT codes for colposcopy with biopsy, and it differs from visualization-only procedures.

In simple terms:

• CPT Code 57455 = Colposcopy with cervical biopsy under anesthesia
• May include ECC
• Tissue is submitted for pathology
• Used when biopsy is medically necessary

Many coders searching for the correct CPT code for colposcopy, CPT colposcopy with biopsy, cervix biopsy CPT code, or CPT code for cervical biopsy are actually looking for CPT 57455.

2) When to Use CPT Code 57455

Report CPT Code 57455 whenever a colposcopy with cervical biopsy is performed under anesthesia.

Common indications include:

• Abnormal Pap smear requiring tissue diagnosis
• Cervical dysplasia (CIN)
• Suspicious cervical lesions
• HPV-related abnormalities
• Biopsy requiring anesthesia because of patient discomfort or procedural complexity

If only diagnostic visualization is performed without biopsy, another colposcopy CPT code such as 57420 may be more appropriate.

When both biopsy and ECC are completed under anesthesia, CPT colposcopy with biopsy and ECC is generally reported using 57455, since the code already includes endocervical curettage when performed.

Providers frequently search for:

• CPT code for colposcopy with biopsy
• CPT for colposcopy with biopsy
• CPT code for colposcopy with cervical biopsy
• CPT for colposcopy with biopsy and ECC

all of which generally refer to CPT 57455 when the documentation supports the procedure.

3) Documentation Requirements

Proper documentation is essential for clean claims and full reimbursement.

The operative report should clearly include:

• Type of anesthesia administered
• Exact cervical biopsy location(s)
• Whether ECC was performed
• Number of biopsy specimens obtained
• Pathology specimens submitted
• Clinical indication for biopsy

Complete documentation supports medical necessity and reduces denials for CPT Code 57455.

4) Common Coding Errors

Some of the most common billing mistakes include:

• Reporting 57420 instead of 57455 when a biopsy was performed
• Billing separate biopsy codes in addition to 57455
• Forgetting to document anesthesia
• Missing pathology documentation
• Using diagnosis codes that do not support medical necessity

These errors often result in delayed payments or payer audits.

5) Reimbursement & Payer Notes

Because biopsy is included, 57455 CPT code generally reimburses at a higher rate than diagnostic colposcopy alone.

Before claim submission:

• Verify payer-specific coverage policies
• Confirm diagnosis supports medical necessity
• Review Medicare LCDs when applicable
• Ensure pathology documentation matches the operative report

Commercial payers generally follow Medicare guidance but may have different reimbursement policies.

6) Best Practices for Billing CPT 57455

To improve reimbursement accuracy:

• Report 57455 only when biopsy is performed.
• Do not bill 57420 together with 57455 for the same encounter.
• Confirm pathology specimens were submitted.
• Link the claim with appropriate ICD-10 diagnosis codes such as:
  • N87.x – Cervical dysplasia
  • R87.61–R87.619 – Abnormal cervical cytology
  • D06.x – Carcinoma in situ of cervix
• Review payer-specific modifier requirements before claim submission.

Following these steps improves claim acceptance while maintaining coding compliance.

Conclusion

CPT Code 57455 is the correct CPT code for colposcopy with biopsy performed under anesthesia and may also include endocervical curettage (ECC) when documented. Accurate documentation of anesthesia, biopsy sites, pathology, and supporting diagnosis codes is essential for proper reimbursement.

Healthcare practices that correctly report 57455 CPT code, maintain complete documentation, and follow payer-specific billing guidelines can significantly reduce denials and improve revenue cycle performance.
