| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| K91.3 | Postprocedural intestinal obstruction | Use when there is a documented mechanical obstruction directly related to surgery. |
|
| K91.89 | Other postprocedural complications and disorders of digestive system | Use when non-obstructive ileus is confirmed as a surgical complication. |
|
| K56.7 | Ileus, unspecified | Use when ileus is not linked to surgery or lacks complication documentation. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Decision Criteria
clinical Criteria
- Presence of mechanical obstruction confirmed by imaging
Applicable To
- Mechanical obstruction due to surgery
Excludes
- Non-obstructive ileus
Clinical Validation Requirements
- Documentation of mechanical obstruction
- Imaging showing transition point
Code-Specific Risks
- Incorrectly coding non-obstructive ileus as K91.3
Coding Notes
- Ensure documentation specifies mechanical obstruction.
K91.89 - Other postprocedural complications and disorders of digestive system
Use when non-obstructive ileus is confirmed as a surgical complication.
Applicable To
- Non-obstructive ileus as a complication
Excludes
- Mechanical obstruction
Clinical Validation Requirements
- Documentation of non-obstructive ileus as a complication
- Interventions such as NG tube placement
Coding Notes
Ensure documentation specifies the ileus as a complication.
K56.7 - Ileus, unspecified
Use when ileus is not linked to surgery or lacks complication documentation.
Applicable To
- Non-obstructive ileus not linked to surgery
Excludes
- Obstructive ileus
Clinical Validation Requirements
- Lack of obstruction on imaging
- No surgical complication documented
Coding Notes
Ensure non-surgical causes are documented.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Postoperative Ileus to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K91.3.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Potential for audit issues., Financial: Incorrect coding can affect reimbursement.
Mitigation Strategy
Clarify if ileus is expected or a complication., Use specific language in documentation.
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Query for 'mechanical vs. paralytic' to ensure correct coding.
Impact
Risk of incorrect coding due to ambiguous documentation.
Mitigation Strategy
Implement clear documentation practices and regular audits.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
