About coding esophagus diffuse spasm
The ICD-10-CM code for esophagus diffuse spasm is K22.4 (Dyskinesia of esophagus). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on K22.4.
Within K22 (other diseases of esophagus), K22.4 is specifically for dyskinesia of esophagus. Related codes cover Achalasia of cardia (K22.0), ulcer of esophagus (K22.1), esophageal obstruction (K22.2), perforation of esophagus (K22.3), diverticulum of esophagus, acquired (K22.5), Gastro-esophageal laceration-hemorrhage syndrome (K22.6), Barrett's esophagus (K22.7), other specified diseases of esophagus (K22.8) and 1 more.
Don't report K22.4 together with the conditions in its Excludes1 note: cardiospasm (K22.0).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
