Non-billable headerICD-10-CM

This code requires a 7th character

The appropriate 7th character is to be added to each code from category S71

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.

Inclusion terms

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

Bite of hip NOS

Excludes1 inherited from the categories above S71.05

These are not written on S71.05, but they bind it: a note on a category applies to every code beneath it. Billing S71.05 with anything listed here is a denial.

Written on S71 — Open wound of hip and thigh

open fracture of hip and thigh (S72.-)
traumatic amputation of hip and thigh (S78.-)

Excludes2 inherited from the categories above S71.05

Also inherited, and the opposite of Excludes1: these conditions are not part of S71.05, but a patient can have both, so you may code both.

Written on S71 — Open wound of hip and thigh

bite of venomous animal (T63.-)
open wound of ankle, foot and toes (S91.-)
open wound of knee and lower leg (S81.-)

Other codes that can never be billed with S71.05

These codes carry an Excludes1 note pointing at S71.05. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S71.05 alone.

Risk adjustment

S71.05 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.

S71.05 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
