T07.XXXA vs T33
T07.XXXA (Unspecified multiple injuries, initial encounter) compared with T33 (Superficial frostbite), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. T07.XXXA carries an Excludes1 note covering T33: “frostbite (T33-T34)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
