S00.12XA vs S00.12XS
S00.12XA (Contusion of left eyelid and periocular area, initial encounter) compared with S00.12XS (Contusion of left eyelid and periocular area, sequela), from the official CMS tabular data. S00.12XA and S00.12XS code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S00.12XA and S00.12XS 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.
