Question:
Primary Site/Priorities--Breast: When there are conflicting references to subsite in different reports, which report has priority? See Discussion.
Discussion:
The clinical site of the palpable mass is outer quadrant. The pathologist states inflammatory breast cancer located in the central breast. Should the site be coded to C501 for central breast, C509 for inflammatory breast ca, or C508 for outer quadrant?
Answer:
Code the breast subsite from the pathology report (C501, central).
The priority order for coding subsite from conflicting reports is
1. Pathology report
2. Operative report
3. Physical examination
4. Mammogram, ultrasound
The primary site of inflammatory breast carcinoma is coded to C509 when there is no palpable tumor.
