S25.29XA (Other specified injury of superior vena cava, initial encounter) compared with S25.29XS (Other specified injury of superior vena cava, sequela), from the official CMS tabular data. S25.29XA and S25.29XS 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.
