S78Traumatic amputation of hip and thigh

Non-billable headerICD-10-CM

S78 is a non-billable header ICD-10-CM code for traumatic amputation 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 category S78

A
initial encounter
D
subsequent encounter
S
sequela

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • traumatic amputation of knee (S88.0-)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • An amputation not identified as partial or complete should be coded to complete

Other codes that can never be billed with S78

These codes carry an Excludes1 note pointing at S78. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S78 alone.

  • S71Open wound of hip and thigh
  • S72Fracture of femur

Risk adjustment

S78 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 S78

3 child codes. Green means billable.
