| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D46.0 | Refractory anemia without ring sideroblasts, so stated | Use when refractory anemia is diagnosed without the presence of ring sideroblasts. |
|
| D46.1 | Refractory anemia with ring sideroblasts | Use when refractory anemia is diagnosed with the presence of ring sideroblasts. |
|
| D46.9 | Myelodysplastic syndrome, unspecified | Use when MDS is diagnosed but specific subtype is not documented. |

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 myelodysplastic syndrome
Decision Criteria
clinical Criteria
- Absence of ring sideroblasts confirmed by bone marrow biopsy.
Applicable To
- Refractory anemia without ring sideroblasts
Excludes
- Refractory anemia with ring sideroblasts (D46.1)
Clinical Validation Requirements
- Bone marrow biopsy showing dysplasia in ≥10% of cells in one or more myeloid cell lines
- Absence of ring sideroblasts
Code-Specific Risks
- Misclassification if ring sideroblasts are present but not documented.
Coding Notes
- Ensure documentation specifies absence of ring sideroblasts.
D46.1 - Refractory anemia with ring sideroblasts
Use when refractory anemia is diagnosed with the presence of ring sideroblasts.
Applicable To
- Refractory anemia with ring sideroblasts
Excludes
- Refractory anemia without ring sideroblasts (D46.0)
Clinical Validation Requirements
- Bone marrow biopsy showing ≥15% ring sideroblasts
- SF3B1 mutation may be present
Coding Notes
Ensure documentation specifies presence of ring sideroblasts.
D46.9 - Myelodysplastic syndrome, unspecified
Use when MDS is diagnosed but specific subtype is not documented.
Applicable To
- Myelodysplastic syndrome NOS
Excludes
- Specific types of myelodysplastic syndromes (D46.0-D46.8)
Clinical Validation Requirements
- General diagnosis of MDS without specific subtype identified
Coding Notes
Encourage specificity in documentation to avoid using unspecified codes.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Myelodysplastic Syndrome to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D46.0.
Impact
Clinical: May lead to inappropriate treatment plans., Regulatory: Increases risk of audit and compliance issues., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Educate clinicians on the importance of detailed documentation., Implement checklists for documentation requirements.
Impact
Reimbursement: May result in lower reimbursement rates., Compliance: Increases risk of audit due to lack of specificity., Data Quality: Reduces accuracy of clinical data.
Mitigation Strategy
Ensure documentation specifies the subtype of MDS for accurate coding.
Impact
High audit risk when using D46.9 without specific subtype documentation.
Mitigation Strategy
Encourage detailed documentation and use of specific codes.
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.
