| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D47.3 | Essential thrombocythemia | Use when essential thrombocythemia is confirmed by bone marrow biopsy and molecular testing. |
|
| D75.838 | Other specified thrombocytosis | Use for reactive thrombocytosis with documented cause. |
|
| D75.839 | Thrombocytosis, unspecified | Use when thrombocytosis is present but not specified as essential or reactive. |

Primary ICD-10-CM Codes for elevated platelet count
Decision Criteria
clinical Criteria
- Confirmed by bone marrow biopsy and JAK2 mutation
Applicable To
- Essential thrombocythemia
Excludes
- Secondary thrombocytosis (D75.838)
Clinical Validation Requirements
- Sustained platelet count >450 x 10^9/L
- Bone marrow biopsy showing megakaryocyte clusters
- JAK2/CALR/MPL mutation positive
Code-Specific Risks
- Incorrect use without bone marrow confirmation
- Confusion with reactive thrombocytosis
Coding Notes
- Ensure molecular testing is documented for essential thrombocythemia.
D75.838 - Other specified thrombocytosis
Use for reactive thrombocytosis with documented cause.
Applicable To
- Reactive thrombocytosis
Excludes
- Essential thrombocythemia (D47.3)
Clinical Validation Requirements
- Platelet count >450 x 10^9/L with known reactive cause
- Elevated CRP or other inflammatory markers
Coding Notes
Document the underlying cause for reactive thrombocytosis.
D75.839 - Thrombocytosis, unspecified
Use when thrombocytosis is present but not specified as essential or reactive.
Excludes
- Essential thrombocythemia (D47.3)
- Other specified thrombocytosis (D75.838)
Clinical Validation Requirements
- Platelet count >450 x 10^9/L without specified cause
Coding Notes
Use only after ruling out essential and reactive causes.
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 Elevated Platelet Count to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D47.3.
Impact
Clinical: May lead to inappropriate treatment, Regulatory: Non-compliance with coding standards, Financial: Potential for claim denials
Mitigation Strategy
Always specify if thrombocytosis is essential or reactive.
Impact
Reimbursement: Potential for reduced reimbursement, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate data representation
Mitigation Strategy
Query for clarification or additional documentation
Impact
High risk of audit if D75.839 is used without proper documentation.
Mitigation Strategy
Ensure documentation specifies essential or reactive causes.
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.
