S82.021A vs S82.021F

S82.021A (Displaced longitudinal fracture of right patella, initial encounter for closed fracture) compared with S82.021F (Displaced longitudinal fracture of right patella, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing), from the official CMS tabular data. S82.021A and S82.021F code the same injury at a different phase of treatment.

Can these codes be reported together?

Same injury, other encounter phase. S82.021A and S82.021F 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.
