M84.559 — Pathological fracture in neoplastic disease, hip, unspecified
M84.559 is a non-billable header ICD-10-CM code for pathological fracture in neoplastic disease, hip, unspecified. 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
Risk adjustment
M84.559 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.
