D47.0 — Mast cell neoplasms of uncertain behavior
D47.0 is a non-billable header ICD-10-CM code for mast cell neoplasms of uncertain behavior. It cannot be billed on its own: choose one of the more specific child codes below.
Other codes that can never be billed with D47.0
These codes carry an Excludes1 note pointing at D47.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D47.0 alone.
Risk adjustment
D47.0 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 history
D47.0 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
