G: subsequent encounter for fracture with delayed healing
K: subsequent encounter for fracture with nonunion
S: sequela

Excludes1 inherited from the categories above S22.49XK

These are not written on S22.49XK, but they bind it: a note on a category applies to every code beneath it. Billing S22.49XK with anything listed here is a denial.

Written on S22.4 — Multiple fractures of ribs

flail chest (S22.5-)

Written on S22 — Fracture of rib(s), sternum and thoracic spine

transection of thorax (S28.1)

Excludes2 inherited from the categories above S22.49XK

Also inherited, and the opposite of Excludes1: these conditions are not part of S22.49XK, but a patient can have both, so you may code both.

Written on S22 — Fracture of rib(s), sternum and thoracic spine

fracture of clavicle (S42.0-)
fracture of scapula (S42.1-)

Other codes that can never be billed with S22.49XK

These codes carry an Excludes1 note pointing at S22.49XK. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S22.49XK alone.

M48.5Collapsed vertebra, not elsewhere classified
M84.3Stress fracture
M84.4Pathological fracture, not elsewhere classified

Risk adjustment

S22.49XK 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.

Medicare coverage

S22.49XK is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
