D24Benign neoplasm of breast

Non-billable headerICD-10-CM

D24 is a non-billable header ICD-10-CM code for benign neoplasm of breast. It cannot be billed on its own: choose one of the more specific child codes below.

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.

  • adenofibrosis of breast (N60.2)
  • benign cyst of breast (N60.-)
  • benign mammary dysplasia (N60.-)
  • benign neoplasm of skin of breast (D22.5, D23.5)
  • fibrocystic disease of breast (N60.-)

Includes

Conditions this code covers.

  • benign neoplasm of connective tissue of breast
  • benign neoplasm of soft parts of breast
  • fibroadenoma of breast

Other codes that can never be billed with D24

These codes carry an Excludes1 note pointing at D24. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D24 alone.

  • D21Other benign neoplasms of connective and other soft tissue

Risk adjustment

D24 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 D24

3 child codes. Green means billable.
