S82.452A vs S82.452M
S82.452A (Displaced comminuted fracture of shaft of left fibula, initial encounter for closed fracture) compared with S82.452M (Displaced comminuted fracture of shaft of left fibula, subsequent encounter for open fracture type I or II with nonunion), from the official CMS tabular data. S82.452A and S82.452M code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S82.452A and S82.452M 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.
