S07.8XXA (Crushing injury of other parts of head, initial encounter) compared with S07.8XXS (Crushing injury of other parts of head, sequela), from the official CMS tabular data. S07.8XXA and S07.8XXS code the same injury at a different phase of treatment. MedCoder-derived
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.
