About coding acetabulum fracture
The ICD-10-CM code for acetabulum fracture is S32.40 (Unspecified fracture of acetabulum). The official index lists 19 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S32.40.
Within S32.4, choose S32.40 (Unspecified fracture of acetabulum) only when documentation doesn't support a more specific option: fracture of anterior wall of acetabulum (S32.41), fracture of posterior wall of acetabulum (S32.42), fracture of anterior column [iliopubic] of acetabulum (S32.43), fracture of posterior column [ilioischial] of acetabulum (S32.44), transverse fracture of acetabulum (S32.45), associated transverse-posterior fracture of acetabulum (S32.46), fracture of medial wall of acetabulum (S32.47), dome fracture of acetabulum (S32.48) and 1 more.
Codes in this range require a 7th character: A for initial encounter for closed fracture, B for initial encounter for open fracture, D for subsequent encounter for fracture with routine healing, G for subsequent encounter for fracture with delayed healing, K for subsequent encounter for fracture with nonunion and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
Code first: any associated spinal cord and spinal nerve injury (S34.-).

Common questions about acetabulum fracture ICD-10 codes
What is the ICD-10 code for acetabulum fracture?
- S32.40 — Unspecified fracture of acetabulum (a header code; report a more specific subcode). More specific codes apply when the documentation supports them: S32.43, S32.436, S32.443, S32.44 and others below.
What is the ICD-10 code for dome acetabulum fracture?
- S32.48 — Dome fracture of acetabulum (header code; choose a more specific subcode).
What is the ICD-10 code for transverse acetabulum fracture?
- S32.45 — Transverse fracture of acetabulum (header code; choose a more specific subcode).
Is S32.40 billable?
- No. S32.40 is a header code. Report one of its more specific subcodes instead.
