Inquiry Details
References:
2004 SEER Manual, C-560 to C-562
Question:
CS Site Specific Factor--Prostate: Are the EOD guidelines developed for coding apex involvement still in effect for determining the code for apical involvement in SSF 4? See Discussion.
Discussion:
How do the old prostate codes 31, 33, and 34 correspond to the new SSF 4 field? Because "arising in" or "extending into" apex is rarely, if ever, stated, previous SEER guidelines instructed us to use code 33 for "apex only" involvement, and code 34 for "apex and any other area of prostate". Code 31 [into/arising, NOS] was to be avoided.
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.No, the EOD guidelines for coding apex involvement are not in effect for coding SSF4.
The codes for CS site specific factor 4 include code 2 [into prostatic apex/arising in prostatic apex, NOS]. When it cannot be determined if apical involvement is arising in, or extending to, the apex, use code 2.
