| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D45 | Polycythemia vera | Use when JAK2 mutation is positive and bone marrow biopsy confirms PV. |
|
| D75.1 | Secondary polycythemia | Use when erythrocytosis is due to an underlying condition with elevated EPO. |

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Erythrocytosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D45.
Impact
Clinical: Misdiagnosis of erythrocytosis type., Regulatory: Non-compliance with coding standards., Financial: Potential for claim denials.
Mitigation Strategy
Ensure EPO levels are tested and documented., Link EPO results to the underlying condition.
Impact
Reimbursement: Incorrect sequencing can lead to denied claims., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Always document and code the underlying condition first.
Impact
Failure to sequence underlying condition first.
Mitigation Strategy
Educate coding staff on sequencing rules.
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.
