C40 — Malignant neoplasm of bone and articular cartilage of limbs
Is C40 billable?

Use additional code
Report an additional code alongside C40 to fully describe the condition. C40 is sequenced first.
- code to identify major osseous defect, if applicable (M89.7-)
Excludes1 — never code together — inherited from C40-C41
The conditions below can never be reported together with C40 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
