D05 — Carcinoma in situ of breast

Non-billable headerICD-10-CM

D05 is a non-billable header ICD-10-CM code for carcinoma in situ of breast. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

carcinoma in situ of skin of breast (D04.5)
melanoma in situ of breast (skin) (D03.5)
Paget's disease of breast or nipple (C50.-)

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

malignant neoplasm of breast (C50.-)

Risk adjustment

D05 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 D05

4 child codes. Green means billable.
