About coding cardia stomach stenosis
The ICD-10-CM code for cardia stomach stenosis is K22.2 (Esophageal obstruction). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on K22.2.
Within K22 (other diseases of esophagus), K22.2 is specifically for esophageal obstruction. Related codes cover Achalasia of cardia (K22.0), ulcer of esophagus (K22.1), perforation of esophagus (K22.3), dyskinesia of esophagus (K22.4), 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 K22.2 together with the conditions in its Excludes1 note: congenital stenosis or stricture of esophagus (Q39.3).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
