Pathological fracture in neoplastic disease
M84.5 is a category heading, not a billable code. CMS does not accept it on a claim; report one of the more specific codes beneath it.
Code also
Two codes may be needed; sequencing depends on the reason for the encounter.
- underlying neoplasm
7th character
- The appropriate 7th character is to be added to each code from subcategory M84.5:
Permitted 7th characters
| 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 |
ICD-10-CM FY2026 defines 9 codes beneath M84.5. See the ICD-10-CM index for what this site publishes.
