S82.55XA vs S82.55XS
S82.55XA (Nondisplaced fracture of medial malleolus of left tibia, initial encounter for closed fracture) compared with S82.55XS (Nondisplaced fracture of medial malleolus of left tibia, sequela), from the official CMS tabular data. S82.55XA and S82.55XS code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S82.55XA and S82.55XS 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.
