Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- neoplasm of uncertain behavior of skin of breast (D48.5)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Neoplasm of uncertain behavior of connective tissue of breast
- Cystosarcoma phyllodes
Other codes that can never be billed with D48.6
These codes carry an Excludes1 note pointing at D48.6. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D48.6 alone.
- D48.1Neoplasm of uncertain behavior of connective and other soft tissue
Risk adjustment
D48.6 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code to one of these instead D48.6
