Question:

Surgery of Primary Site/Reconstruction-First Course--Breast: If the plan is to "reconstruct" the breast 6 months after an ipsilateral modified radical mastectomy, is the time span a problem or should it be coded in the Surgery of Primary Site field because it was planned?

Discussion:

Answer:

For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 55 [Modified radical mastectomy WITHOUT removal of uninvolved contralateral breast, Implant]. The time span is not a problem as long as the reconstruction was planned as first course, which is indicated by tissue expander insertion at the time of the original surgery.

History:

For cases diagnosed 1998-2002: Code the Reconstruction-First Course field to 1 [Reconstruction, NOS (unknown if flap)].
