What code should be used when a primary malignancy has been excised but treatment is still ongoing?

When coding for a primary malignancy that has been excised but is still under treatment, the appropriate choice is to use the primary malignancy code. This ensures that the patient’s medical record accurately reflects their condition as actively being treated for cancer, despite the excision.

The rationale for utilizing the primary malignancy code lies in the guidelines regarding cancer coding, which state that when a malignancy is excised, the primary malignancy code should still be reported if the patient is currently receiving treatment or if future treatment is anticipated. This provides a complete picture of the patient's health status and reflects the ongoing management of their malignancy.

This choice captures the ongoing need for care and monitors the patient’s status as part of their treatment plan. It aligns with the standard coding practices that emphasize continuity in reflecting a patient's active medical conditions. Other codes listed may pertain to different conditions or concepts that do not specifically address the status of a primary malignancy under treatment.
