| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| A41.9 | Sepsis, unspecified organism | When the specific organism causing sepsis is not identified. |
|
| R65.21 | Severe sepsis with septic shock | When septic shock is present, indicating severe sepsis. |

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 systemic infection with organ dysfunction.
Applicable To

Excludes
- Septicemia NOS
Clinical Validation Requirements
- Positive blood culture
- Clinical signs of systemic infection
Code-Specific Risks
- May lead to lower reimbursement if organism is not specified.
Coding Notes
- Ensure that the documentation explicitly links sepsis to organ dysfunction.

When septic shock is present, indicating severe sepsis.
Applicable To
- Septic shock
Excludes
- Sepsis without shock
Clinical Validation Requirements
- Lactate ≥2 mmol/L
- SBP <90 mmHg
- Vasopressor use
Coding Notes
Ensure documentation supports the presence of shock.
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 Severe Sepsis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code A41.9.
Impact
Clinical: Lack of specificity in diagnosis., Regulatory: Non-compliance with coding standards., Financial: Potential for claim denials.
Mitigation Strategy
Use specific terms like 'sepsis due to UTI'., Query providers for clarification.
Impact
Reimbursement: May result in lower reimbursement due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate representation of patient severity.
Mitigation Strategy
Always include codes for organ dysfunction when coding severe sepsis.
Impact
Using A41.9 without identifying the organism.
Mitigation Strategy
Encourage specific organism documentation.
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.
