S34.22XA (Injury of nerve root of sacral spine, initial encounter) compared with S34.22XD (Injury of nerve root of sacral spine, subsequent encounter), from the official CMS tabular data. S34.22XA and S34.22XD 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.

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.
