S56.229A (Laceration of other flexor muscle, fascia and tendon at forearm level, unspecified arm, initial encounter)
compared with
S56.229D (Laceration of other flexor muscle, fascia and tendon at forearm level, unspecified arm, subsequent encounter),
from the official CMS tabular data. S56.229A and S56.229D code the same injury at a different phase of treatment.
Laceration of other flexor muscle, fascia and tendon at forearm level, unspecified arm, 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. S56.229A and S56.229D 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.
