What code should be assigned for fine-needle aspiration biopsies of lesions in both breasts?

1. 10021

2. 10022 × 2

3. 10061

4. 10062

The correct answer is: 10022 × 2

For fine-needle aspiration biopsies (FNAB) of lesions in both breasts, the appropriate code is for the procedure performed on each lesion site. In this case, 10022 is the correct code that corresponds to fine-needle aspiration biopsy of a lesion with a more detailed approach, as it includes imaging guidance or additional complexity. Since the procedure is being performed on two separate breast lesions, it is necessary to multiply the code 10022 by two to accurately represent both biopsies performed. This reflects the additional procedure being done for the second lesion in the other breast. Proper coding practices require accurate representation of multiple procedures, especially when they occur in the same session but on separate anatomical sites. Using one code for both breast lesions (like just 10022) would not appropriately account for all services provided, which is crucial in ensuring that healthcare providers are reimbursed correctly and that patient care is well-documented.
