K91.30Postprocedural intestinal obstruction, unspecified as to partial versus complete

K91.30 is the ICD-10-CM diagnosis code for postprocedural intestinal obstruction, unspecified as to partial versus complete. It belongs to category K91 (intraoperative and postprocedural complications and disorders of digestive system, not elsewhere classified), block K90-K95 (other diseases of the digestive system) and chapter 11 (diseases of the digestive system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within K91.3, choose K91.30 (unspecified as to partial versus complete) only when documentation doesn't support a more specific option: partial intestinal obstruction (K91.31) and complete intestinal obstruction (K91.32).

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.

It was added in FY2018, effective October 1, 2017.

Before ICD-10, this condition was coded in ICD-9-CM as 997.49 (other digestive system complications).
