S32.431A (Displaced fracture of anterior column [iliopubic] of right acetabulum, initial encounter for closed fracture) compared with S32.431S (Displaced fracture of anterior column [iliopubic] of right acetabulum, sequela), from the official CMS tabular data. S32.431A and S32.431S code the same injury at a different phase of treatment.
Same underlying diagnosis, different encounter phase.
The 7th character records the phase of care for the encounter being coded, so a single encounter takes one of these characters, not several. Review whether both phases belong on the same episode of care.

Same injury, other encounter phase. S32.431A and S32.431S 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.
