ICD-10 Code K91.30 – Postprocedural intestinal obstruction, unspecified as to partial versus complete (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K91.30 – Postprocedural intestinal obstruction, unspecified as to partial versus complete
What it is
K91.30 identifies an intestinal obstruction that occurs after a procedure, when the record does not specify whether it is partial or complete. Use it for postoperative blockage involving the bowel.
Clinical signs
Typical findings include abdominal distention, pain, nausea, vomiting, and reduced or absent bowel function. Clinical features vary; refer to documentation for the exact postoperative presentation.
When to use this code
Use this code when the provider documents postprocedural intestinal obstruction but does not state partial versus complete. It is appropriate after surgery or another procedure when the obstruction is clearly linked to that intervention. Check documentation for the operative context and any specified cause.
Do not use for
Do not use it for intestinal obstruction unrelated to a procedure or when the record clearly identifies another postoperative complication. If the chart specifies partial or complete obstruction, verify whether a more specific code applies.
Coding tip
Look for explicit wording tying the obstruction to a prior procedure before assigning K91.30.
