Oncology follow-up in a specialty clinic documents ongoing chemotherapy for a primary malignancy. Which malignancy coding concept is most accurate for risk adjustment?
Select an answer to reveal the explanation.
Short Explanation
If treatment is still fighting the cancer, it is usually still an active malignancy code—not a “history of” postcard. History codes fit when the disease is gone and you are only remembering it. Match the code to the treatment reality.
Full Explanation
When cancer is under active treatment, ICD-10-CM guidance generally supports reporting the active malignancy rather than only a personal history code. Personal history is appropriate when the malignancy has been eradicated and care addresses history/surveillance without active disease. E/M codes do not replace diagnosis capture for risk adjustment, and first-dose rules that force history coding are incorrect.
