Clinical Validation Requirements
- Biopsy confirming CD20+ B-cells
- MRI showing brain/spinal cord lesions
Coding Notes
Ensure documentation specifies primary CNS origin.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Crigler-Najjar Syndrome and CNS Lymphoma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E80.5.
Impact
Clinical: Misrepresentation of patient's condition, Regulatory: Non-compliance with ICD-10 coding guidelines, Financial: Potential claim denials or delays
Mitigation Strategy
Verify diagnosis with biopsy results, Ensure documentation specifies primary CNS involvement
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding standards., Data Quality: Inaccurate clinical data and statistics.
Mitigation Strategy
Verify diagnosis with genetic and biopsy tests.
Impact
Risk of coding CNS lymphoma as unspecified CNS neoplasm.
Mitigation Strategy
Ensure biopsy and imaging results are documented.
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.
