| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D69.3 | Immune thrombocytopenic purpura | Use when primary immune thrombocytopenia is confirmed by exclusion of secondary causes. |
|
| D69.5 | Secondary thrombocytopenia | Use when thrombocytopenia is secondary to another condition. |

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 Thrombocytopenia
Primary ICD-10-CM Codes for immune thrombocytopenia
Decision Criteria
clinical Criteria
- Confirmed exclusion of secondary causes
documentation Criteria
- Documented platelet count <100×10⁹/L
Applicable To
- Primary immune thrombocytopenia
- Idiopathic thrombocytopenic purpura
Clinical Validation Requirements
- Platelet count <100×10⁹/L on multiple occasions
- Exclusion of secondary causes such as lupus or HIV
- Bone marrow examination showing megakaryocytic hyperplasia
Code-Specific Risks
- Misclassification if secondary causes are not ruled out
- Incorrect use in drug-induced cases
Coding Notes
- Ensure documentation specifies 'primary' or 'idiopathic' to use D69.3.
D69.5 - Secondary thrombocytopenia
Use when thrombocytopenia is secondary to another condition.
Applicable To
- Thrombocytopenia due to lupus
- Thrombocytopenia due to HIV
Excludes
- Primary immune thrombocytopenia (D69.3)
Clinical Validation Requirements
- Documentation of underlying condition causing thrombocytopenia
- Temporal relationship to medication or condition
Coding Notes
Ensure the underlying condition is documented and coded.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

D69.5Differential 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 Immune Thrombocytopenia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D69.3.
Impact
Clinical: Leads to misdiagnosis and inappropriate treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to insufficient documentation.
Mitigation Strategy
Ensure detailed documentation of lab results and exclusion of other causes.
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use D69.5 with T45.1X5A for adverse effect.
Impact
Using D69.3 without excluding secondary causes.
Mitigation Strategy
Ensure thorough documentation of exclusion criteria.
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.
