S07.9XXA (Crushing injury of head, part unspecified, initial encounter) compared with S07.9XXS (Crushing injury of head, part unspecified, sequela), from the official CMS tabular data. S07.9XXA and S07.9XXS 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.

The 7th character records the type of care given at the encounter being coded (ICD-10-CM Official Guidelines, Section I.C.19.a), so one encounter takes one of these, not both.
