What is the correct code for needle aspiration of the breast without imaging?

Coding for Needle Aspiration of the Breast Without Imaging

For needle aspiration of the breast without imaging, the correct CPT code is 19000.

Rationale for Code Selection

The American College of Radiology (ACR) Appropriateness Criteria provides guidance on breast procedures and their appropriate use, which helps inform the correct coding selection 1.

Understanding CPT Code 19000

• 19000 is specifically designated for needle aspiration of the breast without imaging guidance
• This code applies to:
  • Palpable breast masses that can be directly accessed without imaging
  • Procedures performed using only clinical examination for guidance
  • Simple aspiration of breast cysts or fluid collections

Differentiation from Other Codes

• 19100: This code is for breast biopsy (not aspiration) without imaging guidance
• 19030: This code is for injection procedure only for mammary ductogram/galactogram
• 10021/10022: These are general fine needle aspiration codes that are not specific to breast procedures

Clinical Context for Needle Aspiration Without Imaging

The ACR Appropriateness Criteria provides context for when non-image guided procedures might be appropriate 1, 2:

1. Patient Age Considerations:

   • For women under 30: Ultrasound is typically the first imaging modality, but palpable masses may be aspirated directly if clinically appropriate
   • For women 30-39: Either ultrasound or mammography is appropriate first, but direct aspiration may be performed for obvious cysts
   • For women over 40: While imaging is generally recommended before intervention, direct aspiration may be appropriate for clearly palpable, mobile masses with classic cystic features

2. Appropriateness Ratings:

   • The ACR rates image-guided fine-needle aspiration as "usually not appropriate" (rating of 1-2) as an initial procedure for most palpable breast masses 1
   • This suggests that when FNA is performed, it is often done without imaging guidance (code 19000) or after imaging has already characterized the lesion

Important Clinical Considerations

When performing needle aspiration without imaging guidance:

• Documentation Requirements:

  • Document the location, size, and characteristics of the palpable mass
  • Note the amount and appearance of fluid aspirated
  • Document post-procedure assessment of the mass

• Common Pitfalls to Avoid:

  • Using 19000 when imaging guidance was actually employed (should use 19001 or 10022 with appropriate imaging codes)
  • Confusing aspiration (19000) with core needle biopsy (19100)
  • Failing to document medical necessity for the procedure

• Clinical Effectiveness:

  • Fine needle aspiration has a reported specificity of 99% and sensitivity of 70-99% 3
  • False negative rates can range from 0.7-22%, with higher rates in tumors under 2cm 3

Conclusion

Based on the ACR Appropriateness Criteria and coding guidelines, 19000 is the correct CPT code for needle aspiration of the breast without imaging guidance. This code specifically describes the procedure of aspirating fluid or cells from a palpable breast mass using only clinical examination for guidance.
