S82.046A vs S82.046M
S82.046A (Nondisplaced comminuted fracture of unspecified patella, initial encounter for closed fracture) compared with S82.046M (Nondisplaced comminuted fracture of unspecified patella, subsequent encounter for open fracture type I or II with nonunion), from the official CMS tabular data. S82.046A and S82.046M code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S82.046A and S82.046M 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.
