| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D69.3 | Immune thrombocytopenic purpura | Use when ITP is confirmed and no secondary causes are identified. |
|
| D69.4 | Other primary thrombocytopenia | Use when primary thrombocytopenia is confirmed but not immune-mediated. |

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

Essential facts and insights about Immune Thrombocytopenic Purpura
Primary ICD-10-CM Codes for immune thrombocytopenic purpura
Decision Criteria
clinical Criteria
- Platelet count consistently below 100×10⁹/L with no secondary causes
documentation Criteria
- Documentation must explicitly state 'immune thrombocytopenic purpura'
Applicable To
- Idiopathic thrombocytopenic purpura
- Primary immune thrombocytopenia
Clinical Validation Requirements
- Platelet count <100×10⁹/L
- Exclusion of secondary causes
- Peripheral smear showing decreased platelets
Code-Specific Risks
- Misclassification if secondary causes are not ruled out
- Incorrect use if documentation does not specify 'immune' or 'idiopathic'
Coding Notes
- Ensure documentation specifies 'immune' or 'idiopathic' to avoid misclassification.
D69.4 - Other primary thrombocytopenia
Use when primary thrombocytopenia is confirmed but not immune-mediated.
Applicable To
- Congenital thrombocytopenia
- Familial thrombocytopenia
Excludes
- Immune thrombocytopenic purpura (D69.3)
Clinical Validation Requirements
- Thrombocytopenia with no immune or idiopathic cause
- Negative antiplatelet antibodies
Coding Notes
Ensure thorough documentation to differentiate from immune causes.
Ancillary Codes

D69.5Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Immune Thrombocytopenic Purpura to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D69.3.
Impact
Clinical: Potential misdiagnosis of ITP, Regulatory: Non-compliance with coding standards, Financial: Incorrect billing and reimbursement
Mitigation Strategy
Thorough review of patient history, Comprehensive lab testing
Impact
Reimbursement: May lead to incorrect DRG assignment and reimbursement issues, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data representation
Mitigation Strategy
Ensure all secondary causes are ruled out before using D69.3
Impact
Failure to document exclusion of secondary causes can lead to audit issues.
Mitigation Strategy
Implement a checklist for exclusion of secondary causes in documentation.
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.
