Question:

Sugery of Primary Site--Breast: When a patient is simultaneously diagnosed with bilateral breast cancer and bilateral mastectomies are done, do you code the total mastectomies to 40 or 41 or 42?

Discussion:

Answer:

Abstract cancer of the left breast and cancer of the right breast as separate primaries. Code the surgery for each primary independent of the other primary.

For the first primary, assign code 41 [Total (simple) mastectomy, NOS WITHOUT removal of uninvolved contralateral breast].

For the second primary, assign the code for the procedure performed on that site.
