An oncology infusion suite in a physician practice documents an encounter for antineoplastic chemotherapy with primary breast cancer still under treatment. Which diagnosis concept pairing is appropriate?
Select an answer to reveal the explanation.
Short Explanation
Chemo day with cancer still being treated: you need the encounter-for-chemo concept and the active breast cancer—not a history code that pretends it's over. History waits until treatment is done and the record says so.
Full Explanation
Encounters for antineoplastic chemotherapy commonly use an encounter-for-chemotherapy diagnosis sequenced according to Official Guidelines, with the malignancy under treatment also coded as active disease. Personal history of malignant neoplasm is incorrect while primary breast cancer remains under antineoplastic therapy. Screening or unrelated symptom substitution does not replace the chemotherapy encounter and active cancer concepts on a physician-practice infusion claim.
