Parastomal hernia codes with specifications for obstruction and gangrene
These codes are used to specify the presence of a parastomal hernia with or without complications such as obstruction or gangrene.
Codes for stoma status
These codes are used as secondary codes to indicate the presence of a stoma, which is relevant for parastomal hernias.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| K43.5 | Parastomal hernia without obstruction or gangrene | Use when the hernia is reducible and there are no signs of obstruction or gangrene. |
|
| K43.6 | Parastomal hernia with obstruction | Use when there is evidence of bowel obstruction associated with the hernia. |
|
| K43.4 | Parastomal hernia with gangrene | Use when gangrene or necrosis is confirmed in the hernia. |

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

Essential facts and insights about Parastomal Hernia
Primary ICD-10-CM Codes for parastomal hernia
Decision Criteria
clinical Criteria
- Hernia is reducible with no signs of obstruction or gangrene.
Applicable To
- Reducible parastomal hernia
Clinical Validation Requirements
- Clinical examination confirming reducibility
- Absence of symptoms indicating obstruction or gangrene
Code-Specific Risks
- Misclassification if obstruction or gangrene is present but not documented
Coding Notes
- Ensure documentation clearly states the absence of obstruction or gangrene.
K43.6 - Parastomal hernia with obstruction
Use when there is evidence of bowel obstruction associated with the hernia.
Applicable To
- Incarcerated parastomal hernia
Excludes
- Parastomal hernia without obstruction (K43.5)
- Parastomal hernia with gangrene (K43.4)
Clinical Validation Requirements
- Imaging showing bowel obstruction
- Clinical signs of obstruction such as vomiting or abdominal pain
Coding Notes
Ensure documentation specifies obstruction to avoid misclassification.
K43.4 - Parastomal hernia with gangrene
Use when gangrene or necrosis is confirmed in the hernia.
Applicable To
- Strangulated parastomal hernia
Excludes
- Parastomal hernia without obstruction (K43.5)
- Parastomal hernia with obstruction (K43.6)
Clinical Validation Requirements
- Surgical findings of necrotic bowel
- Elevated lactate levels indicating ischemia
Coding Notes
Document gangrene explicitly to support this code.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Parastomal Hernia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K43.5.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims or reduced reimbursement.
Mitigation Strategy
Use specific terms like 'incarcerated' or 'strangulated'., Ensure imaging and surgical findings are clearly documented.
Impact
Reimbursement: Incorrect coding can lead to denied claims or incorrect DRG assignment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient records.
Mitigation Strategy
Use specific parastomal hernia codes (K43.4-K43.6) based on clinical findings.
Impact
Reimbursement: Incomplete coding may affect reimbursement rates., Compliance: Failure to comply with coding standards., Data Quality: Incomplete patient records.
Mitigation Strategy
Always include a Z93 code to indicate stoma status.
Impact
Using separate mesh codes when they are included in the primary procedure code.
Mitigation Strategy
Educate coding staff on the inclusion of mesh in specific procedure codes.
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.
