| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E43 | Unspecified severe protein-calorie malnutrition | Use when severe malnutrition is documented without specification of marasmus or kwashiorkor. |
|
| E41 | Nutritional marasmus | Use when marasmus is documented with severe wasting and no edema. |

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
- Severe weight loss and low BMI
documentation Criteria
- Explicit mention of 'severe malnutrition'
Clinical Validation Requirements

Code-Specific Risks
- Risk of incorrect coding if severity is not explicitly documented.
Coding Notes
- Ensure severity is documented by the provider, not inferred from lab results.
E41 - Nutritional marasmus
Use when marasmus is documented with severe wasting and no edema.
Applicable To
- Severe wasting without edema
Excludes
- Kwashiorkor (E40)
Clinical Validation Requirements
- Documentation of 'nutritional marasmus'
- BMI <14 for adults
Coding Notes
Ensure absence of edema is documented.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Protein Malnutrition to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E43.
Impact
Clinical: Misrepresentation of patient's condition severity., Regulatory: Potential audit findings and penalties., Financial: Denied claims and reduced reimbursement.
Mitigation Strategy
Educate providers on documentation requirements, Implement documentation checklists
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure provider documents 'severe' explicitly.
Impact
Lack of documented severity can trigger audits.
Mitigation Strategy
Ensure all documentation includes explicit severity indicators.
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.
