S68.422A (Partial traumatic amputation of left hand at wrist level, initial encounter) compared with S68.422S (Partial traumatic amputation of left hand at wrist level, sequela), from the official CMS tabular data. S68.422A and S68.422S 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.
