D47.3Primary Range
Neoplasms of uncertain behavior of lymphoid, hematopoietic and related tissue
This range includes essential thrombocythemia, a primary condition characterized by elevated platelet counts due to clonal proliferation.
Other specified diseases of blood and blood-forming organs
This range includes secondary or reactive thrombocytosis, which is not a primary clonal disorder.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D47.3 | Essential (hemorrhagic) thrombocythemia | Use when documentation specifies essential or primary thrombocythemia with supporting lab results. |
|
| D75.838 | Other specified thrombocytosis | Use when thrombocytosis is secondary to another condition, such as infection or inflammation. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Code-Specific Risks
- Misclassification if genetic testing is not documented
- Incorrect use if reactive causes are not excluded
Coding Notes
- Ensure documentation specifies 'essential' or 'primary' to use D47.3.
D75.838 - Other specified thrombocytosis
Use when thrombocytosis is secondary to another condition, such as infection or inflammation.
Applicable To
- Reactive thrombocytosis
Excludes
- Essential thrombocythemia (D47.3)
Clinical Validation Requirements
- Documentation of underlying cause
- Transient platelet elevation
Coding Notes
Ensure linkage to the secondary cause is documented.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Essential Thrombocytosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D47.3.
Impact
Clinical: Potential misdiagnosis and inappropriate treatment., Regulatory: Non-compliance with documentation standards., Financial: Claim denials due to insufficient documentation.
Mitigation Strategy
Educate providers on documentation requirements, Implement checklist for thrombocytosis documentation
Impact
Reimbursement: Potential denial of claims due to lack of supporting documentation., Compliance: Non-compliance with coding guidelines requiring specific documentation., Data Quality: Inaccurate clinical data affecting patient records.
Mitigation Strategy
Ensure documentation includes genetic testing results or query the provider.
Impact
Lack of genetic testing documentation for essential thrombocythemia.
Mitigation Strategy
Ensure all cases of D47.3 have documented genetic test results.
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.
