Question 20091038
Inquiry Details
References:
2007 SEER Manual, 125, C-605 to C-607. Appendix C
Question:
CS Tumor Size--Breast: Do the tumor size instructions in the CS Manual take priority over those in the SEER manual? See Discussion.
Discussion:
In regards to priority order of sources to be used in coding size for breast and lung, we are instructed to use the site-specific instructions in the 2004 SEER Manual over the general instructions in the CS Manual (see SINQ 20061109). Thus, physical exam size would be used over an imaging size. I&R question 2389 instructs registrars to use an imaging size over a physical exam size. This inconsistency creates confusion for them. Do the answers given in I&R not take into account the information in the SEER Manual? As a SEER Registry, which rules do we tell our hospitals to use? Are ACoS accredited hospitals required to use I&R over SINQ?
Answer:
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.The current SEER instructions and the CS instructions for source of tumor size information are the same. The tumor size priority source instruction in the 2004 SEER manual is not included in the 2007 SEER manual. SINQ 20061109 has been updated for clarification. There is no conflict between SEER instructions and I&R instructions at this time. SEER and the CoC collaborate, endeavoring to provide consistent instructions and to resolve inconsistencies.
