About K90.8
K90.8 is the ICD-10-CM diagnosis code for other intestinal malabsorption. It belongs to category K90 (intestinal malabsorption), block K90-K95 (other diseases of the digestive system) and chapter 11 (diseases of the digestive system). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.
Within K90, choose K90.8 (Other intestinal malabsorption) only when documentation doesn't support a more specific option: celiac disease (K90.0), tropical sprue (K90.1), blind loop syndrome, not elsewhere classified (K90.2), pancreatic steatorrhea (K90.3), other malabsorption due to intolerance (K90.4) and unspecified (K90.9).
To report this condition, pick the subcode that matches the documentation: K90.81 (disease), K90.82 (syndrome), K90.83 (failure) and K90.89 (malabsorption).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
