S79 — Other and unspecified injuries of hip and thigh
S79 is a non-billable header ICD-10-CM code for other and unspecified injuries of hip and thigh. 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 subcategories S79.0 and S79.1
- A
- initial encounter for closed 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
Notes
Additional guidance from the ICD-10-CM tabular list.
- A fracture not indicated as open or closed should be coded to closed
Other codes that can never be billed with S79
These codes carry an Excludes1 note pointing at S79. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S79 alone.
Risk adjustment
S79 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.
Code to one of these instead S79
4 child codes. Green means billable.
