About coding bleeding ulcer
The ICD-10-CM code for bleeding ulcer is K27.4 (Chronic or unspecified peptic ulcer, site unspecified, with hemorrhage).
Within K27, choose K27.4 (Chronic or unspecified peptic ulcer, site unspecified, with hemorrhage) only when documentation doesn't support a more specific option: acute peptic ulcer, site unspecified, with hemorrhage (K27.0), acute peptic ulcer, site unspecified, with perforation (K27.1), acute peptic ulcer, site unspecified, with both hemorrhage and perforation (K27.2), acute peptic ulcer, site unspecified, without hemorrhage or perforation (K27.3), chronic or unspecified peptic ulcer, site unspecified, with perforation (K27.5), chronic or unspecified peptic ulcer, site unspecified, with both hemorrhage and perforation (K27.6), chronic peptic ulcer, site unspecified, without hemorrhage or perforation (K27.7) and unspecified as acute or chronic, without hemorrhage or perforation (K27.9).
Use an additional code to identify: alcohol abuse and dependence (F10.-).
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.
