S99.022A vs S99.022B

S99.022A (Salter-Harris Type II physeal fracture of left calcaneus, initial encounter for closed fracture) compared with S99.022B (Salter-Harris Type II physeal fracture of left calcaneus, initial encounter for open fracture), from the official CMS tabular data. S99.022A and S99.022B code the same injury at a different phase of treatment.

Can these codes be reported together?

Same injury, other encounter phase. S99.022A and S99.022B 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.
