About S32.412

S32.412 is the ICD-10-CM diagnosis code for displaced fracture of anterior wall of left 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 S32.41 (fracture of anterior wall of acetabulum), S32.412 is specifically for displaced fracture of anterior wall of left acetabulum. Related codes cover displaced fracture of anterior wall of right acetabulum (S32.411), displaced fracture of anterior wall of unspecified acetabulum (S32.413), nondisplaced fracture of anterior wall of right acetabulum (S32.414), nondisplaced fracture of anterior wall of left acetabulum (S32.415) and nondisplaced fracture of anterior wall of unspecified acetabulum (S32.416).

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.
