S31.30XA (Unspecified open wound of scrotum and testes, initial encounter) compared with S31.30XD (Unspecified open wound of scrotum and testes, subsequent encounter), from the official CMS tabular data. S31.30XA and S31.30XD 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.
