Question:
Discussion:
Specifically, CS Ext code 80 includes nodular involvement of the lungs. The CT report for this patient states that the lungs are nodular. Is that enough to use code 80? Can the liver be coded as involved based on the operative findings?
Scenario: The patient was diagnosed with lymphoma. The CT showed pulmonary nodules. The pt had an exploratory laparotomy with a positive mesenteric LN bx and a positive ileocecectomy. The operative findings included a nodular liver. No staging was done by the oncologist and he has the pt on CHOP-R.
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.
Extension code 80 can be assigned based on imaging or operative findings as in the lymphoma case described above. The fact that this extension was not based on pathological evidence is captured in the evaluation code. Assign CS/TS Ext-Eval code 0 [No staging laparotomy done. No autopsy evidence used (clinical)].
