ICD-10 code for Peridiverticulitis

The ICD-10-CM code for Peridiverticulitis is K57.92 (Diverticulitis of intestine, part unspecified, without perforation or abscess without bleeding).

Within K57.9, choose K57.92 (Diverticulitis of intestine, part unspecified, without perforation or abscess without bleeding) only when documentation doesn't support a more specific option: Diverticulosis of intestine, part unspecified, without perforation or abscess without bleeding (K57.90), Diverticulosis of intestine, part unspecified, without perforation or abscess with bleeding (K57.91) and Diverticulitis of intestine, part unspecified, without perforation or abscess with bleeding (K57.93).

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.
