Z85.4A
ICD-10-CMThis code indicates a patient's past medical history of a primary malignant tumor originating in one or both fallopian tubes. It signifies that the malignancy has been definitively diagnosed and successfully treated, and the patient is currently cancer-free from this specific site. This code is used for surveillance and follow-up care, not for active cancer treatment.
Apply this code for patients who have completed treatment (e.g., surgery, chemotherapy, radiation) for fallopian tube cancer and are now in remission or under post-treatment surveillance. It is appropriate when the patient is seen for routine follow-up appointments, screening for recurrence, or management of long-term side effects related to the past fallopian tube malignancy. Do not use this code if the patient has active, recurrent, or metastatic fallopian tube cancer.
