SEER Summary Stage 2000
Question:
Summary Stage 2000--Melanoma: How should Summary Stage 2000 be coded for 2014+ diagnosed melanoma cases with satellite nodules or in transit metastases? See discussion.
Discussion:
The SEER SS (SSS) 2000 Manual indicates satellite nodules (NOS or less than/equal to 2cm from primary tumor) are regional by direct extension (code 2) and in-transit metastasis (satellite nodules greater than 2 cm from primary tumor) are coded as involvement of regional lymph nodes (code 3). However, CSv0205 indicates mapping for satellite nodules/in transit metastasis (coded in CS LN) was changed to Regional, NOS (code 5). There are no definitions listed for code 5 in the SSS 2000 Manual.
Our staff independently code SSS 2000. Should we code the existence of satellite nodules and in transit metastases according to the current definitions in the SSS 2000 Manual or using the mapping information from CSv0205?
Answer:
Code the existence of satellite nodules and in transit metastases according to the current definitions in the SSS 2000 Manual. Do not use the mapping information from CS to code SSS.
