Question:

Histology (Pre-2007)--Breast: What code is used for histology "tubular carcinoma with lobular carcinoma in situ"?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Assign code 8211/3 [Tubular carcinoma]. According to histology rule #2 for a single tumor on page 86 of the 2004 SEER manual, code the invasive histology when both invasive and in situ tumor are present.

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 prior to 2004: Code the Histology field to 8211/3 [tubular carcinoma]. Apply the second rule for coding complex breast histologies: "If the diagnosis is mixed invasive and in situ, code the invasive diagnosis."
