Question: How should we code a metastatic breast cancer in which the breast was removed in the 1980s but the cancer has returned in the lung? New Jersey Subscriber Answer: AHA guidelines dictate that "Any mention of extension, invasion, or metastasis to another site is coded as a secondary malignant neoplasm to that site. The secondary site may be the principal or first-listed with the V10 code [Personal history of malignant neoplasm] used as a secondary code."

Hickey, MS, MSN, RN, OCN, CORLN, an independent coding consultant based in New Orleans; Linda L.

The cancer that they found at this episode is a lung cancer, so it should be coded as secondary lung (197.0) followed by V10.3 (Personal history of breast cancer).
