About coding primary steatorrhea
The ICD-10-CM code for primary steatorrhea is K90.0 (Celiac disease).
Within K90 (intestinal malabsorption), K90.0 is specifically for celiac disease. Related codes cover tropical sprue (K90.1), blind loop syndrome, not elsewhere classified (K90.2), pancreatic steatorrhea (K90.3), other malabsorption due to intolerance (K90.4), other intestinal malabsorption (K90.8) and unspecified (K90.9).
Use an additional code for associated disorders including: dermatitis herpetiformis (L13.0) and gluten ataxia (G32.81).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
