| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E43 | Unspecified severe protein-calorie malnutrition | Use when severe malnutrition is documented with specific clinical findings. |
|
| E44.0 | Moderate protein-calorie malnutrition | Use when moderate malnutrition is documented with specific clinical findings. |
|
| E44.1 | Mild protein-calorie malnutrition | Use when mild malnutrition is documented with specific clinical findings. |
|
| R64 | Cachexia | Use when cachexia is documented with non-nutritional etiology. |

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
- Weight loss >5% in 1 month and muscle wasting
Applicable To
- Severe malnutrition
Excludes
- Cachexia (R64)
Clinical Validation Requirements
- Weight loss >5% in 1 month
- Muscle wasting
Code-Specific Risks
- Incorrect use without meeting ASPEN criteria
Coding Notes
- Ensure documentation meets ASPEN criteria for severe malnutrition.
E44.0 - Moderate protein-calorie malnutrition
Use when moderate malnutrition is documented with specific clinical findings.
Applicable To
- Moderate malnutrition
Excludes
- Severe malnutrition (E43)
Clinical Validation Requirements
- Weight loss 2-5%
- Mild fat/muscle loss
Coding Notes
Ensure documentation specifies moderate malnutrition with clinical findings.
E44.1 - Mild protein-calorie malnutrition
Use when mild malnutrition is documented with specific clinical findings.
Applicable To
- Mild malnutrition
Excludes
- Moderate malnutrition (E44.0)
Clinical Validation Requirements
- Weight loss <2%
- No muscle loss
Coding Notes
Ensure documentation specifies mild malnutrition with clinical findings.
R64 - Cachexia
Use when cachexia is documented with non-nutritional etiology.
Applicable To
- Wasting syndrome
Excludes
- Severe malnutrition (E43)
Clinical Validation Requirements
- Chronic inflammation
- Weight loss
Coding Notes
Ensure documentation links cachexia to chronic disease.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Malnutrition to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E43.
Impact
Clinical: Inaccurate clinical assessment, Regulatory: Non-compliance with coding standards, Financial: Potential loss of reimbursement
Mitigation Strategy
Use specific clinical criteria, Follow ASPEN guidelines
Impact
Reimbursement: $3470/claim, Compliance: High risk of audit, Data Quality: Inaccurate severity classification
Mitigation Strategy
Use E44.1 unless ASPEN criteria are met.
Impact
Reimbursement: Potential claim denial, Compliance: Non-compliance with coding guidelines, Data Quality: Incomplete clinical picture
Mitigation Strategy
Code R64 with underlying condition.
Impact
High risk of audit if E43 is used without meeting ASPEN criteria.
Mitigation Strategy
Ensure documentation includes specific clinical findings.
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.
