S82.311A vs S82.311K
S82.311A (Torus fracture of lower end of right tibia, initial encounter for closed fracture) compared with S82.311K (Torus fracture of lower end of right tibia, subsequent encounter for fracture with nonunion), from the official CMS tabular data. S82.311A and S82.311K code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S82.311A and S82.311K 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.
