Is S32.309 a billable ICD-10-CM code?

No. S32.309 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does S32.309 sit in the tabular list?

Injury, poisoning and certain other consequences of external causes (S00-T88), in the block Injuries to the abdomen, lower back, lumbar spine, pelvis and external genitals (S30-S39).

What cannot be coded together with S32.309?

S32.309 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above S32.309 (S32.3, S32) and apply to it just the same.

S32.309 — Unspecified fracture of unspecified ilium

Non-billable headerICD-10-CM

S32.309 is a non-billable header ICD-10-CM code for unspecified fracture of unspecified ilium. 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 S32

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
S: sequela

Excludes1 inherited from the categories above S32.309

These are not written on S32.309, but they bind it: a note on a category applies to every code beneath it. Billing S32.309 with anything listed here is a denial.

Written on S32.3 — Fracture of ilium

fracture of ilium with associated disruption of pelvic ring (S32.8-)

Written on S32 — Fracture of lumbar spine and pelvis

transection of abdomen (S38.3)

Excludes2 inherited from the categories above S32.309

Also inherited, and the opposite of Excludes1: these conditions are not part of S32.309, 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 S32.309

These codes carry an Excludes1 note pointing at S32.309. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S32.309 alone.

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

Risk adjustment

S32.309 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

S32.309 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead S32.309
