A41.5-A41.59Primary Range
Sepsis due to Gram-negative organisms
This range includes codes for sepsis caused by specific Gram-negative bacteria, which is crucial for accurate diagnosis and treatment.
Other bacterial agents as the cause of diseases classified elsewhere
These codes are used to specify the bacterial agent causing the infection, providing additional detail to the primary diagnosis.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| A41.5 | Sepsis due to other Gram-negative organisms | Use when sepsis is confirmed to be due to Gram-negative bacteria, but the specific organism is not further specified. |
|
| A41.50 | Sepsis due to unspecified Gram-negative organism | Use when sepsis is due to Gram-negative bacteria, but the specific organism is not identified. |

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 Gram-negative bacterial infections
Primary ICD-10-CM Codes for gram negative bacteria
Decision Criteria
clinical Criteria
- Presence of positive blood cultures for Gram-negative bacteria
documentation Criteria
- Explicit mention of Gram-negative organism in clinical notes
Applicable To
- Sepsis due to Gram-negative bacteria
Clinical Validation Requirements
- Positive blood cultures for Gram-negative bacteria
- Clinical signs of sepsis such as fever, hypotension, or elevated lactate
Code-Specific Risks
- Risk of undercoding if specific organism is identified but not documented
Coding Notes
- Ensure documentation specifies the Gram-negative organism when possible to avoid using unspecified codes.
A41.50 - Sepsis due to unspecified Gram-negative organism
Use when sepsis is due to Gram-negative bacteria, but the specific organism is not identified.
Applicable To
- Sepsis due to unspecified Gram-negative bacteria
Excludes
- Sepsis due to specified Gram-negative organisms (A41.51-A41.59)
Clinical Validation Requirements
- Clinical diagnosis of sepsis with Gram-negative bacteria identified via gram stain but not speciated
Coding Notes
Ensure documentation supports the use of unspecified codes only when organism identification is not possible.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Gram-negative bacterial infections to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code A41.5.
Impact
Clinical: May lead to inappropriate treatment choices, Regulatory: Increased risk of audit, Financial: Potential for reduced reimbursement
Mitigation Strategy
Educate providers on documentation standards, Implement checklists for sepsis documentation
Impact
Reimbursement: May lead to lower reimbursement due to lack of specificity, Compliance: Increases risk of audit for incorrect coding, Data Quality: Reduces data quality for epidemiological tracking
Mitigation Strategy
Ensure documentation specifies the organism and use the appropriate specific code.
Impact
High audit risk if specific organisms are documented but not coded.
Mitigation Strategy
Regular audits of sepsis documentation to ensure organism specificity is captured.
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.
