About coding loop syndrome blind

The ICD-10-CM code for loop syndrome blind is K90.2 (Blind loop syndrome, not elsewhere classified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on K90.2.

Within K90 (intestinal malabsorption), K90.2 is specifically for blind loop syndrome, not elsewhere classified. Related codes cover celiac disease (K90.0), tropical sprue (K90.1), pancreatic steatorrhea (K90.3), other malabsorption due to intolerance (K90.4), other intestinal malabsorption (K90.8) and unspecified (K90.9).

Don't report K90.2 together with the conditions in its Excludes1 note: congenital blind loop syndrome (Q43.8) and postsurgical blind loop syndrome (K91.2).

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.
