S26.11XA (Contusion of heart without hemopericardium, initial encounter) compared with S26.11XS (Contusion of heart without hemopericardium, sequela), from the official CMS tabular data. S26.11XA and S26.11XS 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.
