About D24
D24 is the ICD-10-CM diagnosis code for benign neoplasm of breast. It belongs to block D10-D36 (benign neoplasms, except benign neuroendocrine tumors) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: D24.1 (breast), D24.2 (breast) and D24.9 (breast).
The conditions in its Excludes2 note aren't part of D24, but may be coded alongside it if the patient has both: adenofibrosis of breast (N60.2), benign cyst of breast (N60.-), benign mammary dysplasia (N60.-), benign neoplasm of skin of breast (D22.5, D23.5) and 1 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
