S82.434A vs S82.434M
S82.434A (Nondisplaced oblique fracture of shaft of right fibula, initial encounter for closed fracture) compared with S82.434M (Nondisplaced oblique fracture of shaft of right fibula, subsequent encounter for open fracture type I or II with nonunion), from the official CMS tabular data. S82.434A and S82.434M code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S82.434A and S82.434M 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.
