S95.112A (Laceration of plantar artery of left foot, initial encounter) compared with S95.112S (Laceration of plantar artery of left foot, sequela), from the official CMS tabular data. S95.112A and S95.112S 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.
