Documentation & Coding Risks

Avoid these common issues when documenting Protein Deficiency.

Lack of ASPEN criteria documentation

Impact

Clinical: Inaccurate assessment of malnutrition severity, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials

Mitigation

Ensure ASPEN criteria are documented, Conduct thorough nutritional assessments

Missing genetic test results for coagulation disorders

Impact

Clinical: Misdiagnosis of coagulation disorders, Regulatory: Non-compliance with coding guidelines, Financial: Incorrect DRG assignment

Mitigation

Verify genetic testing is completed, Document test results in the medical record

Using E43 without meeting ASPEN criteria

Impact

Reimbursement: Potential denial of claims, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate representation of patient condition

Mitigation

Ensure documentation includes ≥2 ASPEN criteria.

Confusing D68.51 with congenital deficiencies

Impact

Reimbursement: Incorrect DRG assignment, Compliance: Coding inaccuracies, Data Quality: Misleading patient records

Mitigation

Verify genetic testing results for APC resistance.

Severe Malnutrition Coding

Impact

High denial rates for E43 due to lack of ASPEN criteria documentation.

Mitigation

Ensure documentation includes ≥2 ASPEN criteria.

Coagulation Disorder Coding

Impact

Incorrect coding of D68.51 without genetic confirmation.

Mitigation

Verify genetic testing results are documented.
