| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D47.3 | Essential thrombocythemia | Use when thrombocytosis is confirmed as essential with genetic markers and exclusion of secondary causes. |
|
| D75.81 | Secondary 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.

Primary ICD-10-CM Codes for thrombocythemia
Decision Criteria
clinical Criteria
- Presence of JAK2 mutation and sustained high platelet count
documentation Criteria
- Exclusion of reactive causes documented
Applicable To
- Primary thrombocytosis
Excludes
- Reactive thrombocytosis (D75.81)
Clinical Validation Requirements
- JAK2/CALR/MPL mutation
- Sustained platelet count >450k/µL
- Bone marrow biopsy confirmation
Code-Specific Risks
- Misclassification without genetic confirmation
- Inadequate documentation of exclusion of secondary causes
Coding Notes
- Ensure documentation includes genetic testing results and exclusion of secondary causes.
D75.81 - Secondary 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
- Platelet elevation with identifiable reactive cause
- Normal CRP and ESR levels
Coding Notes
Ensure the underlying condition is coded first.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Thrombocythemia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D47.3.
Impact
Clinical: Misdiagnosis of thrombocythemia type., Regulatory: Non-compliance with coding standards., Financial: Potential claim denials.
Mitigation Strategy
Always document exclusion of reactive causes in the patient's record.
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure genetic testing confirms essential thrombocythemia before using D47.3.
Impact
Using D47.3 without proper documentation of essential thrombocythemia.
Mitigation Strategy
Ensure all documentation requirements are met before coding.
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.
