| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| A41.9 | Sepsis, unspecified organism | Use when sepsis is diagnosed without a specified organism or location. |
|
| R65.20 | Severe sepsis without septic shock | Use when sepsis is accompanied by acute organ dysfunction but no septic shock. |

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

Primary ICD-10-CM Codes for sepsis
Decision Criteria
clinical Criteria
- Presence of systemic infection signs and symptoms.
Applicable To
- Septicemia NOS
Excludes
- Septic shock (R65.21)
Clinical Validation Requirements
- Fever
- WBC >12k/<4k
- Documented 'sepsis' without organ failure
Code-Specific Risks
- Misuse when specific organism is known but not documented.
Coding Notes
- Ensure documentation specifies 'sepsis' and not vague terms like 'urosepsis'.
R65.20 - Severe sepsis without septic shock
Use when sepsis is accompanied by acute organ dysfunction but no septic shock.
Applicable To
- Severe sepsis NOS
Excludes
- Septic shock (R65.21)
Clinical Validation Requirements
- Lactate ≥2 mmol/L
- qSOFA ≥2
- Documented organ dysfunction
Coding Notes
Ensure organ dysfunction is clearly linked to sepsis in documentation.
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 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: Leads to ambiguous diagnosis., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims.
Mitigation Strategy
Clarify if 'urosepsis' refers to UTI with systemic involvement.
Impact
Reimbursement: May lead to incorrect DRG assignment and reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure organ dysfunction is documented and linked to sepsis.
Impact
Coding sepsis without specifying the organism can lead to audits.
Mitigation Strategy
Ensure lab results specify organism and are documented.
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.
