S52.323A (Displaced transverse fracture of shaft of unspecified radius, initial encounter for closed fracture)
compared with
S52.323Q (Displaced transverse fracture of shaft of unspecified radius, subsequent encounter for open fracture type I or II with malunion),
from the official CMS tabular data. S52.323A and S52.323Q code the same injury at a different phase of treatment.
Displaced transverse fracture of shaft of unspecified radius, subsequent encounter for open fracture type I or II with malunion
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. S52.323A and S52.323Q 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.
