S20.96XA vs S20.96XS
S20.96XA (Insect bite (nonvenomous) of unspecified parts of thorax, initial encounter) compared with S20.96XS (Insect bite (nonvenomous) of unspecified parts of thorax, sequela), from the official CMS tabular data. S20.96XA and S20.96XS code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. S20.96XA and S20.96XS 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.
