T34.62XA vs T34.62XS

T34.62XA (Frostbite with tissue necrosis of left hip and thigh, initial encounter) compared with T34.62XS (Frostbite with tissue necrosis of left hip and thigh, sequela), from the official CMS tabular data. T34.62XA and T34.62XS code the same injury at a different phase of treatment.

Can these codes be reported together?

Same injury, other encounter phase. T34.62XA and T34.62XS 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.
