About coding Linitis plastica
The ICD-10-CM code for Linitis plastica is C16.9 (Malignant neoplasm of stomach, unspecified).
Within C16, choose C16.9 (unspecified) only when documentation doesn't support a more specific option: cardia (C16.0), fundus of stomach (C16.1), body of stomach (C16.2), pyloric antrum (C16.3), pylorus (C16.4), lesser curvature of stomach, unspecified (C16.5), greater curvature of stomach, unspecified (C16.6) and overlapping sites of stomach (C16.8).
Use an additional code to identify: alcohol abuse and dependence (F10.-).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
