K46Primary Range
Unspecified abdominal hernia
This range covers unspecified hernias where the type or location is not specified in the documentation.
Specific types of hernias (inguinal, femoral, umbilical, etc.)
These ranges are used when the hernia type or location is specified, taking precedence over K46.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| K46.0 | Unspecified abdominal hernia with obstruction, without gangrene | Use when documentation confirms obstruction but not gangrene. |
|
| K46.1 | Unspecified abdominal hernia with gangrene | Use when gangrene is confirmed during surgery. |
|
| K46.9 | Unspecified abdominal hernia without obstruction or gangrene | Use when no obstruction or gangrene is documented. |

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

Excludes
- Hernia without gangrene (K46.0, K46.9)
Clinical Validation Requirements
- Operative findings of necrotic tissue
- Elevated lactate levels
Coding Notes
Gangrene must be confirmed intraoperatively.
K46.9 - Unspecified abdominal hernia without obstruction or gangrene
Use when no obstruction or gangrene is documented.
Applicable To
- Abdominal hernia NOS
Excludes
- Hernia with obstruction (K46.0)
- Hernia with gangrene (K46.1)
Clinical Validation Requirements
- Physical exam showing reducible hernia without signs of obstruction
Coding Notes
Ensure no specific type or complication is documented.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Unspecified Hernia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K46.0.
Impact
Clinical: Inaccurate clinical picture, Regulatory: Potential audit issues, Financial: Loss of reimbursement for higher complexity cases
Mitigation Strategy
Thorough documentation of surgical findings, Regular coder-provider communication
Impact
Reimbursement: Incorrect DRG assignment leading to potential underpayment, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data representation
Mitigation Strategy
Use K43.9 for ventral hernias without obstruction or gangrene.
Impact
High risk of audit if unspecified codes are used when specific codes are applicable.
Mitigation Strategy
Ensure thorough documentation and query providers when necessary.
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.
