| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E51 | Thiamine deficiency | Use when documentation specifies thiamine deficiency without further detail. |
|
| E51.1 | Beriberi | Use when documentation specifies symptoms of beriberi. |
|
| E51.2 | Wernicke's Encephalopathy | Use when documentation specifies symptoms of Wernicke's Encephalopathy. |
|
| E51.8 | Other manifestations of thiamine deficiency | Use when documentation specifies non-classic symptoms of thiamine deficiency. |
|
| E51.9 | Thiamine deficiency, unspecified | Use only if no specific manifestation is documented. |

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 thiamine deficiency
Decision Criteria
clinical Criteria
- Presence of clinical symptoms consistent with thiamine deficiency.
Applicable To
- Thiamine deficiency not otherwise specified
Excludes
- Sequelae of nutritional deficiency (E64.8)
Clinical Validation Requirements
- Clinical symptoms of thiamine deficiency
- Laboratory confirmation of low thiamine levels
Code-Specific Risks
- Risk of undercoding if specific manifestations are not documented.
Coding Notes
- Ensure documentation specifies thiamine deficiency to avoid using unspecified codes.
E51.1 - Beriberi
Use when documentation specifies symptoms of beriberi.
Applicable To
- Dry beriberi
- Wet beriberi
Clinical Validation Requirements
- Symptoms such as peripheral edema, cardiomegaly, or neurologic symptoms
- Laboratory confirmation of low thiamine levels
Coding Notes
Ensure documentation includes specific symptoms of beriberi.
E51.2 - Wernicke's Encephalopathy
Use when documentation specifies symptoms of Wernicke's Encephalopathy.
Applicable To
- Acute Wernicke's encephalopathy
Clinical Validation Requirements
- Presence of the clinical triad: oculomotor abnormalities, ataxia, confusion
- MRI findings or laboratory confirmation of low thiamine levels
Coding Notes
Ensure documentation includes the full clinical triad for accurate coding.
E51.8 - Other manifestations of thiamine deficiency
Use when documentation specifies non-classic symptoms of thiamine deficiency.
Applicable To
- Peripheral neuropathy due to thiamine deficiency
Clinical Validation Requirements
- Symptoms such as peripheral neuropathy or aphonia
- Laboratory confirmation of low thiamine levels
Coding Notes
Ensure documentation specifies the specific manifestations of thiamine deficiency.
E51.9 - Thiamine deficiency, unspecified
Use only if no specific manifestation is documented.
Clinical Validation Requirements
- General symptoms of thiamine deficiency without specific manifestation
Coding Notes
Use only when specific manifestations are not documented.

F10.9Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Thiamine Deficiency to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E51.
Impact
Clinical: May lead to inappropriate treatment., Regulatory: Non-compliance with coding standards., Financial: Potential for claim denials.
Mitigation Strategy
Confirm deficiency with lab tests before coding.
Impact
Reimbursement: May lead to claim denials., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate representation of patient health data.
Mitigation Strategy
Do not code as deficiency unless confirmed by lab results.
Impact
Reimbursement: Potential for lower reimbursement rates., Compliance: Non-compliance with specificity requirements., Data Quality: Loss of detailed clinical data.
Mitigation Strategy
Use specific codes like E51.1 or E51.2 based on documented symptoms.
Impact
Coding prophylactic thiamine as deficiency.
Mitigation Strategy
Ensure lab confirmation of deficiency before coding.
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.
