X34 vs X36
X34 (Earthquake) compared with X36 (Avalanche, landslide and other earth movements), 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. X36 carries an Excludes1 note covering X34: “earthquake (X34)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
