S10.95XA (Superficial foreign body of unspecified part of neck, initial encounter) compared with S10.95XD (Superficial foreign body of unspecified part of neck, subsequent encounter), from the official CMS tabular data. S10.95XA and S10.95XD 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.
