| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R79.83 | Abnormal findings of blood amino-acid levels | Use when elevated homocysteine is detected without a specific genetic cause. |
|
| E72.11 | Homocystinuria | Use when homocystinuria is confirmed by genetic testing. |
|
| E72.12 | MTHFR deficiency | Use when MTHFR deficiency is confirmed by genetic testing. |

Coding Notes
- Ensure documentation specifies homocysteine levels and excludes genetic causes.
E72.11 - Homocystinuria
Use when homocystinuria is confirmed by genetic testing.
Applicable To
- CBS deficiency
Excludes
- Hyperhomocysteinemia (R79.83)
Clinical Validation Requirements
- Genetic confirmation of CBS deficiency
- Homocysteine level >13.9 μmol/L
Coding Notes
Documentation must include genetic test results confirming CBS deficiency.
E72.12 - MTHFR deficiency
Use when MTHFR deficiency is confirmed by genetic testing.
Applicable To
- MTHFR C677T polymorphism
Clinical Validation Requirements
- Genetic testing showing MTHFR polymorphism
- Homocysteine level 15-30 μmol/L
Coding Notes
Ensure genetic testing results are documented.
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 Elevated Homocysteine to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R79.83.
Impact
Clinical: Inadequate data for clinical management., Regulatory: Potential audit issues., Financial: Denied claims due to insufficient documentation.
Mitigation Strategy
Train staff on documentation standards., Use templates to ensure completeness.
Impact
Reimbursement: Incorrect DRG assignment leading to reimbursement issues., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient care.
Mitigation Strategy
Verify genetic testing results to confirm homocystinuria.
Impact
Failure to document genetic test results for homocystinuria.
Mitigation Strategy
Implement checklist for genetic testing documentation.
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.
