Inquiry Details
References:
2004 SEER Manual, 5
Question:
Surgery of Primary Site--Breast: How is the surgery field coded when an excisional biopsy that is originally stated to be negative is later determined to be positive on ROS and a mastectomy with negative findings is performed 2 years later? See Discussion.
Discussion:
Hospital 'A' performed a breast biopsy and found only atypia. Two years later Hospital 'B' re-read the first biopsy as multifocal ductal carcinoma in situ, cribriform type. A mastectomy at Hospital 'B' followed and all specimens from this were negative.
Do we report the procedure at Hospital 'A' an excisional biopsy, despite the negative findings at the time?
Answer:
For hospital A, follow the instructions in the 2004 SEER Manual on page 5, #4. For hospital B, the case is not reportable.
The diagnosis date is the date of first excision. Code the breast excision from Hospital A as surgery, first course treatment. The mastectomy was not part of first course treatment.
