Z85 series

ICD-10-CM codes used to report a personal history of malignant neoplasm when the primary malignancy has been excised/eradicated, no active treatment is directed to that site, and there is no evidence of existing disease.

Code C80.0

The ICD-10-CM code for disseminated malignant neoplasm, unspecified, assigned only when a patient has advanced metastatic disease with no known primary or secondary sites specified.
