compared with
S91.131D (Puncture wound without foreign body of right great toe without damage to nail, subsequent encounter),

Puncture wound without foreign body of right great toe without damage to nail, subsequent encounter
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.

Can these codes be reported together?
Same injury, other encounter phase. S91.131A and S91.131D code the same injury at a different phase of treatment, set by the 7th character.
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.
