K: subsequent encounter for fracture with nonunion
S: sequela

Excludes1 inherited from the categories above S32.464B

These are not written on S32.464B, but they bind it: a note on a category applies to every code beneath it. Billing S32.464B with anything listed here is a denial.

Written on S32 — Fracture of lumbar spine and pelvis

transection of abdomen (S38.3)

Excludes2 inherited from the categories above S32.464B

Also inherited, and the opposite of Excludes1: these conditions are not part of S32.464B, but a patient can have both, so you may code both.

Written on S32 — Fracture of lumbar spine and pelvis

fracture of hip NOS (S72.0-)

Other codes that can never be billed with S32.464B

These codes carry an Excludes1 note pointing at S32.464B. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S32.464B alone.

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