About coding Boerhaave's syndrome
The ICD-10-CM code for Boerhaave's syndrome is K22.3 (Perforation of esophagus).
Within K22 (other diseases of esophagus), K22.3 is specifically for perforation of esophagus. Related codes cover Achalasia of cardia (K22.0), ulcer of esophagus (K22.1), esophageal obstruction (K22.2), 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 K22.3 together with the conditions in its Excludes1 note: traumatic perforation of (thoracic) esophagus (S27.8-).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
Don't confuse with (Excludes1 for K22.3)
- traumatic perforation of (thoracic) esophagus (S27.8-)
