T62.91XA vs T62.91XS
T62.91XA (Toxic effect of unspecified noxious substance eaten as food, accidental (unintentional), initial encounter) compared with T62.91XS (Toxic effect of unspecified noxious substance eaten as food, accidental (unintentional), sequela), from the official CMS tabular data. T62.91XA and T62.91XS code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T62.91XA and T62.91XS 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.
