Non-billable headerICD-10-CM

M90.6 is a non-billable header ICD-10-CM code for osteitis deformans in neoplastic diseases. 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.

osteitis deformans [Paget's disease of bone] (M88.-)

Code first

The underlying condition must be sequenced before this code.

the neoplasm (C40.-, C41.-)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Osteitis deformans in malignant neoplasm of bone

Other codes that can never be billed with M90.6

These codes carry an Excludes1 note pointing at M90.6. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M90.6 alone.

Risk adjustment

M90.6 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 M90.6

10 child codes. Green means billable.
