K22.2Esophageal obstruction

K22.2 is the ICD-10-CM diagnosis code for esophageal obstruction. It belongs to category K22 (other diseases of esophagus), block K20-K31 (diseases of esophagus, stomach and duodenum) and chapter 11 (diseases of the digestive system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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.

In MS-DRG v44.0, it is part of the grouping logic for DRG 391 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCC, relative weight 1.2392) and DRG 392 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, relative weight 0.7645), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 530.3 (stricture and stenosis of esophagus).
