S82.426A vs S82.426Q
S82.426A (Nondisplaced transverse fracture of shaft of unspecified fibula, initial encounter for closed fracture) compared with S82.426Q (Nondisplaced transverse fracture of shaft of unspecified fibula, subsequent encounter for open fracture type I or II with malunion), from the official CMS tabular data. S82.426A and S82.426Q code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S82.426A and S82.426Q 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.
