K22.0 vs K22.4
K22.0 (Achalasia of cardia) compared with K22.4 (Dyskinesia of esophagus), 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. K22.4 carries an Excludes1 note covering K22.0: “cardiospasm (K22.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
