Which MS-DRGs does K42.0 group to?
K42.0 sits in MDC 06 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 393Other Digestive System Diagnoses with MCCmedical
- 394Other Digestive System Diagnoses with CCmedical
- 395Other Digestive System Diagnoses without CC/MCCmedical
As a secondary diagnosis, K42.0 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from K42
The conditions below can never be reported together with K42.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- omphalocele (Q79.2)
Excludes2 — not included here — inherited from Chapter 11
The conditions below are not part of K42.0, but a patient may have both at the same time. When documentation supports it, K42.0 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
How long has K42.0 existed?
