S76.399A (Other specified injury of muscle, fascia and tendon of the posterior muscle group at thigh level, unspecified thigh, initial encounter)
compared with
S76.399S (Other specified injury of muscle, fascia and tendon of the posterior muscle group at thigh level, unspecified thigh, sequela),
from the official CMS tabular data. S76.399A and S76.399S code the same injury at a different phase of treatment.
Other specified injury of muscle, fascia and tendon of the posterior muscle group at thigh level, unspecified thigh, sequela
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. S76.399A and S76.399S 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.
