Non-billable headerICD-10-CM

This code requires a 7th character
The appropriate 7th character is to be added to each code from M84.75:
- 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
M84.75 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.
