K91.30 — Postprocedural intestinal obstruction, unspecified as to partial versus complete
Is K91.30 billable?
Yes, but K91.30 is an unspecified code. K91.30 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, K91.30 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting K91.30 — the more specific alternatives are listed below.

Which MS-DRGs does K91.30 group to?
K91.30 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.
- 388Gastrointestinal Obstruction with MCCmedical
- 389Gastrointestinal Obstruction with CCmedical
- 390Gastrointestinal Obstruction without CC/MCCmedical
As a secondary diagnosis, K91.30 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
