K57.52Diverticulitis of both small and large intestine without perforation or abscess without bleeding

K57.52 is the ICD-10-CM diagnosis code for Diverticulitis of both small and large intestine without perforation or abscess without bleeding. It belongs to category K57 (Diverticular disease of intestine), 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 K57.5, choose K57.52 (Diverticulitis of both small and large intestine without perforation or abscess without bleeding) only when documentation doesn't support a more specific option: Diverticulosis of both small and large intestine without perforation or abscess without bleeding (K57.50), Diverticulosis of both small and large intestine without perforation or abscess with bleeding (K57.51) and Diverticulitis of both small and large intestine without perforation or abscess with bleeding (K57.53).

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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 562.01 (Diverticulitis of small intestine (without mention of hemorrhage)) and 562.11 (Diverticulitis of colon (without mention of hemorrhage)).
