About coding sprue
The ICD-10-CM code for sprue is K90.1 (Tropical sprue). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K90.1.
Within K90 (intestinal malabsorption), K90.1 is specifically for tropical sprue. Related codes cover celiac disease (K90.0), 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).
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.
In MS-DRG v44.0, it is part of the grouping logic for DRG 391 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCC, relative weight 1.2392) and DRG 392 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, relative weight 0.7645), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
