About S32.45

S32.45 is the ICD-10-CM diagnosis code for transverse fracture of acetabulum. It belongs to category S32 (fracture of lumbar spine and pelvis), block S30-S39 (injuries to the abdomen, lower back, lumbar spine, pelvis and external genitals) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

Within S32.4 (fracture of acetabulum), S32.45 is specifically for transverse fracture of acetabulum. Related codes cover unspecified fracture of acetabulum (S32.40), 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), 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.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
