Non-billable headerICD-10-CMleft

S42.472 is a non-billable header ICD-10-CM code for displaced transcondylar fracture of left humerus. 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 all codes from category S42

A: initial encounter for closed fracture
B: initial encounter for open 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

Excludes1 inherited from the categories above S42.472

These are not written on S42.472, but they bind it: a note on a category applies to every code beneath it. Billing S42.472 with anything listed here is a denial.

Written on S42 — Fracture of shoulder and upper arm

traumatic amputation of shoulder and upper arm (S48.-)

Excludes2 inherited from the categories above S42.472

Also inherited, and the opposite of Excludes1: these conditions are not part of S42.472, but a patient can have both, so you may code both.

Written on S42.4 — Fracture of lower end of humerus

fracture of shaft of humerus (S42.3-)
physeal fracture of lower end of humerus (S49.1-)

Written on S42 — Fracture of shoulder and upper arm

periprosthetic fracture around internal prosthetic shoulder joint (M97.3)

Other codes that can never be billed with S42.472

These codes carry an Excludes1 note pointing at S42.472. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S42.472 alone.

M84.3Stress fracture
M84.4Pathological fracture, not elsewhere classified

Risk adjustment

S42.472 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 history

S42.472 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
