What is the ICD-10 code for elevated platelet count?

The ICD-10 code for elevated platelet count depends on the cause: D47.3 for essential thrombocythemia, D75.838 for reactive thrombocytosis, and D75.839 for unspecified thrombocytosis.

How do you document essential thrombocythemia?

Document essential thrombocythemia with sustained platelet count, bone marrow biopsy results, and molecular testing confirmation.

Code	Description	When to Use	Key Documentation
D47.3	Essential thrombocythemia	Use when essential thrombocythemia is confirmed by bone marrow biopsy and molecular testing.	Sustained platelet count >450 x 10^9/L Bone marrow biopsy showing megakaryocyte clusters JAK2/CALR/MPL mutation positive
D75.838	Other specified thrombocytosis	Use for reactive thrombocytosis with documented cause.	Platelet count >450 x 10^9/L with known reactive cause Elevated CRP or other inflammatory markers
D75.839	Thrombocytosis, unspecified	Use when thrombocytosis is present but not specified as essential or reactive.	Platelet count >450 x 10^9/L without specified cause

Documentation & Coding Risks

Avoid these common issues when documenting Elevated Platelet Count.

Documenting thrombocytosis without specifying type

Impact

Clinical: May lead to inappropriate treatment, Regulatory: Non-compliance with coding standards, Financial: Potential for claim denials

Mitigation

Always specify if thrombocytosis is essential or reactive.

Using D75.839 without specifying essential or reactive causes

Impact

Reimbursement: Potential for reduced reimbursement, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate data representation

Mitigation

Query for clarification or additional documentation

Use of unspecified codes

Impact

High risk of audit if D75.839 is used without proper documentation.

Mitigation

Ensure documentation specifies essential or reactive causes.
