M84.552 — Pathological fracture in neoplastic disease, left femur
M84.552 is a non-billable header ICD-10-CM code for pathological fracture in neoplastic disease, left femur. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.
This code requires a 7th character
The appropriate 7th character is to be added to each code from subcategory M84.5:
- A
- initial encounter for fracture
- D
- subsequent encounter for fracture with routine healing
- G
- subsequent encounter for fracture with delayed healing
- K
- subsequent encounter for fracture with nonunion
- P
- subsequent encounter for fracture with malunion
- S
- sequela
Excludes2 inherited from the categories above M84.552
Also inherited, and the opposite of Excludes1: these conditions are not part of M84.552, but a patient can have both, so you may code both.

- traumatic fracture of bone-see fracture, by site
Risk adjustment
M84.552 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.

M84.552 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
