About K56.52

K56.52 is the ICD-10-CM diagnosis code for intestinal adhesions [bands] with complete obstruction. It belongs to category K56 (paralytic ileus and intestinal obstruction without hernia), block K55-K64 (other diseases of intestines) 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 K56.5 (intestinal adhesions [bands] with obstruction (postinfection)), K56.52 is specifically for intestinal adhesions [bands] with complete obstruction. Related codes cover [bands], unspecified as to partial versus complete obstruction (K56.50) and [bands], with partial obstruction (K56.51).

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) and DRG 390 (Gastrointestinal Obstruction without CC/MCC, relative weight 0.5404), 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.

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

Before ICD-10, this condition was coded in ICD-9-CM as 560.81 (intestinal or peritoneal adhesions with obstruction (postoperative) (postinfection)).
