S32.445A vs S32.445K
S32.445A (Nondisplaced fracture of posterior column [ilioischial] of left acetabulum, initial encounter for closed fracture) compared with S32.445K (Nondisplaced fracture of posterior column [ilioischial] of left acetabulum, subsequent encounter for fracture with nonunion), from the official CMS tabular data. S32.445A and S32.445K code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S32.445A and S32.445K code the same injury at a different phase of treatment, set by the 7th character.
The 7th character records the type of care given at the encounter being coded (ICD-10-CM Official Guidelines, Section I.C.19.a), so one encounter takes one of these, not both.
