ICD-10 code for radiation enteritis

The ICD-10-CM code for radiation enteritis is K52.0 (Gastroenteritis and colitis due to radiation).

Within K52 (other and unspecified noninfective gastroenteritis and colitis), K52.0 is specifically for gastroenteritis and colitis due to radiation. Related codes cover toxic gastroenteritis and colitis (K52.1), allergic and dietetic gastroenteritis and colitis (K52.2), indeterminate colitis (K52.3), other specified noninfective gastroenteritis and colitis (K52.8) and noninfective gastroenteritis and colitis, unspecified (K52.9).

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 393 (Other Digestive System Diagnoses with MCC, relative weight 1.5881), DRG 394 (Other Digestive System Diagnoses with CC, relative weight 0.9228) and DRG 395 (Other Digestive System Diagnoses without CC/MCC, relative weight 0.6382), 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.
