Non-billable headerICD-10-CM

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.

Excludes1 — never code together

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

congenital cutaneous mastocytosis (Q82.2)
histiocytic neoplasms of uncertain behavior (D47.Z9)
malignant mast cell neoplasm (C96.2-)

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.

L50Urticaria
Q82.2Congenital cutaneous mastocytosis
C96.2Malignant mast cell neoplasm
D47.01Cutaneous mastocytosis
D89.4Mast cell activation syndrome and related disorders

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 to one of these instead D47.0

3 child codes. Green means billable.
