MS-DRG 390: GASTROINTESTINAL OBSTRUCTION WITHOUT CC/MCC
MS-DRG 390 is gastrointestinal obstruction without cc/mcc, in MDC 06 (a medical DRG), at the without-CC/MCC level. Its FY2027 relative weight is 0.5404, so a case here pays less than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 2.20 days. 19 ICD-10-CM principal diagnoses group into MS-DRGs 388–390 under the CMS definitions manual; the most-searched are listed below.

Principal diagnoses that group to MS-DRGs 388–390
From the CMS MS-DRG definitions manual’s principal-diagnosis index: 19 ICD-10-CM codes route here, and the CC/MCC status of the secondary diagnoses decides which of 388–390 the case lands in. The 19 most-searched:
- K56.609Unspecified intestinal obstruction, unspecified as to partial versus complete obstruction
- K56.2Volvulus
- K56.41Fecal impaction
- K56.699Other intestinal obstruction unspecified as to partial versus complete obstruction
- K56.7Ileus, unspecified
- K56.600Partial intestinal obstruction, unspecified as to cause
- K56.1Intussusception
- K56.50Intestinal adhesions [bands], unspecified as to partial versus complete obstruction
- K56.0Paralytic ileus
- K56.3Gallstone ileus
- K56.49Other impaction of intestine
- K56.51Intestinal adhesions [bands], with partial obstruction
- K56.52Intestinal adhesions [bands] with complete obstruction
- K56.601Complete intestinal obstruction, unspecified as to cause
- K56.690Other partial intestinal obstruction
- K56.691Other complete intestinal obstruction
- K91.30Postprocedural intestinal obstruction, unspecified as to partial versus complete
