Inquiry Details
References:
#1: SEER Program Code Man,3rd Ed, 13
#2: 2004 SEER Manual, 13
Question:
Multiple Primaries (Pre-2007)--Thyroid: Does the rule in the 3rd Edition of the SEER Program Code Manual apply to cases diagnosed before 1998 that states if there are two separate carcinomas in the thyroid, one papillary and the other follicular, it is one primary and coded to the combination code 8340/3 [Papillary and follicular carcinoma]? See discussion.
Discussion:
If the rule applies to cases diagnosed before 1998, does SEER plan to ask that cases diagnosed prior to 1998 be recoded?
Answer:
The rule applies to tumors diagnosed 1998-2006. The rule is not retroactive. At this time, SEER does not plan to ask that tumors diagnosed prior to 1998 be recoded.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
History:
For cases diagnosed prior to 1998: Code these cases as two primaries.
