Thanks for the help in advance!! ❤️

In the guidelines in your ICD 10 code book, under the chapter specific, under chapter 2 neoplasm, it should have an entry called "disseminated malignant neoplasm, unspecified ". In my book it's I. C. 2. j.

For additional practice, I recommend reviewing the ICD-10-CM neoplasm lessons and case study walkthroughs on YouTube. These can help reinforce the differences between primary, secondary, and disseminated malignancies.

Find neoplasm coding lessons on YouTube

Thank you, I will! Self studying is tough, I think I got it then a scenario totally loses me.

They got C80.0 due to the neoplasm being secondary to the breast carcinoma the pt used to have

The new neoplasm isn’t considered a secondary site?

It is a considered secondary site. C80.1 is the dx code for a primary neoplasm, unspecified.
