T67.01XA vs T67.01XD
T67.01XA (Heatstroke and sunstroke, initial encounter) compared with T67.01XD (Heatstroke and sunstroke, subsequent encounter), from the official CMS tabular data. T67.01XA and T67.01XD code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T67.01XA and T67.01XD 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.
