What is the ICD-10 code for elevated red blood cells?

The ICD-10 code for elevated red blood cells without a specific cause is R71.8. For polycythemia vera, use D45, and for secondary polycythemia, use D75.1.

How do you code polycythemia vera?

Polycythemia vera is coded as D45 in ICD-10. Ensure documentation includes JAK2 mutation status and elevated hemoglobin levels.

What documentation is needed for secondary polycythemia?

Document the underlying cause, such as chronic hypoxia, and confirm with lab tests like erythropoietin levels and ABG results.

Compare key differences between these codes to ensure accurate selection

Code	Description	When to Use	Key Documentation
D45	Polycythemia vera	Use when polycythemia vera is confirmed by genetic testing and clinical criteria.	JAK2 V617F mutation Hemoglobin >16.5 g/dL (men) or >16.0 g/dL (women) Bone marrow biopsy showing panmyelosis
D75.1	Secondary polycythemia	Use when polycythemia is secondary to another condition like COPD.	Erythropoietin level >30 mIU/mL Chronic hypoxia confirmed by ABG or pulse oximetry
R71.8	Other specified abnormality of red blood cells	Use when elevated RBCs are noted but no specific cause is identified.	Exclusion of primary and secondary causes Consistent elevated RBC count without specific diagnosis

Documentation & Coding Risks

Avoid these common issues when documenting Elevated Red Blood Cell.

Failing to document underlying cause for secondary polycythemia

Impact

Clinical: May lead to inappropriate treatment plans., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to insufficient documentation.

Mitigation

Always investigate and document the underlying cause., Use specific codes for underlying conditions.

Using R71.8 when a specific cause is identified

Impact

Reimbursement: May lead to incorrect DRG assignment and reimbursement issues., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data representation in health records.

Mitigation

Use D45 or D75.1 when specific criteria for these conditions are met.

Incorrect coding of erythrocytosis

Impact

Risk of audits due to incorrect differentiation between primary and secondary causes.

Mitigation

Implement thorough documentation practices and regular coder training.
