About coding esophagus abscess
The ICD-10-CM code for esophagus abscess is K20.80 (Other esophagitis without bleeding).
Within K20.8, choose K20.80 (without bleeding) only when documentation doesn't support a more specific option: with bleeding (K20.81).
Use an additional code to identify: alcohol abuse and dependence (F10.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
