Question:
Surgery of Primary Site--Breast: Is the surgery code 42 or 52? Does it matter that the procedure states no axillary LN, but the pathology found 2 additional LN? See discussion.
Discussion:
Procedure stated = Bilateral skin-sparing mastectomies, left axillary sentinel lymph node biopsy. On the pathology report it indicates two additional lymph nodes were removed that were not SLN. The axillary aspect measures 2 x 2 x 1 cm. Two lymph nodes are identified ranging from 0.5 up to 1 cm. The lymph nodes are bisected and entirely submitted. Final Diagnosis Left breast, mastectomy including nipple: no residual carcinoma; FINAL DIAGNOSIS for LN = Lymph nodes, left axillary sentinel #1; excision: Two lymph nodes examined - negative for tumor (0/2); Two lymph nodes - negative for tumor (0/2)
Answer:
Assign surgery of primary site code 42. It is possible to obtain lymph nodes in a mastectomy specimen without an axillary dissection. Remember to capture the excised lymph nodes in the scope of lymph node surgery field.
