About coding esophagus barrett's
The ICD-10-CM code for esophagus barrett's is K22.70 (Barrett's esophagus without dysplasia). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K22.70.
Within K22.7, choose K22.70 (without dysplasia) only when documentation doesn't support a more specific option: with dysplasia (K22.71).
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 380 (Complicated Peptic Ulcer with MCC, relative weight 1.9245), DRG 381 (Complicated Peptic Ulcer with CC, relative weight 1.0838) and DRG 382 (Complicated Peptic Ulcer without CC/MCC, relative weight 0.7281), 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.
