ICD-10 code for intestine obstruction

The ICD-10-CM code for intestine obstruction is K56.609 (Unspecified intestinal obstruction, unspecified as to partial versus complete obstruction). The official index lists 30 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K56.609.

Within K56.60, choose K56.609 (unspecified as to partial versus complete obstruction) only when documentation doesn't support a more specific option: partial intestinal obstruction, unspecified as to cause (K56.600) and complete intestinal obstruction, unspecified as to cause (K56.601).

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 388 (Gastrointestinal Obstruction with MCC, relative weight 1.4709), DRG 389 (Gastrointestinal Obstruction with CC, relative weight 0.7891), DRG 390 (Gastrointestinal Obstruction without CC/MCC, relative weight 0.5404), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 06 (Diseases and Disorders of the Digestive System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
