| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E43 | Unspecified severe protein-calorie malnutrition | Use when severe malnutrition is documented with specific clinical findings such as significant weight loss and low albumin levels. |
|
| E44.0 | Moderate protein-calorie malnutrition | Use when moderate malnutrition is documented with specific clinical findings. |

Coding Notes
- Ensure documentation includes both quantitative and qualitative assessments of malnutrition severity.
E44.0 - Moderate protein-calorie malnutrition
Use when moderate malnutrition is documented with specific clinical findings.
Applicable To
- Moderate malnutrition
Excludes
- Severe malnutrition (E43)
- Mild malnutrition (E44.1)
Clinical Validation Requirements
- 2-5% weight loss in 1 month
- Reduced intake
- Mild muscle wasting
Coding Notes
Ensure documentation of both weight loss percentage and intake reduction.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Malnourishment to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E43.
Impact
Clinical: Inaccurate diagnosis, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials
Mitigation Strategy
Ensure physician reviews and confirms dietitian assessments, Include physician's documentation in the medical record
Impact
Reimbursement: Potential for claim denial or reduced reimbursement, Compliance: Increased audit risk, Data Quality: Inaccurate clinical data representation
Mitigation Strategy
Ensure documentation includes both weight loss and laboratory findings.
Impact
High risk of audit if coding lacks supporting documentation
Mitigation Strategy
Ensure comprehensive documentation of clinical findings and lab results.
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.
