| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C93.10 | Chronic myelomonocytic leukemia, not having achieved remission | Use when CMML is active and not in remission. |
|
| C93.11 | Chronic myelomonocytic leukemia, in remission | Use when CMML is documented as in remission. |
|
| C93.12 | Chronic myelomonocytic leukemia, in relapse | Use when CMML is documented as relapsed. |

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

Decision Criteria
clinical Criteria
- Monocytosis ≥1 x 10⁹/L and ≥10% of WBCs
coding Criteria
- Do not use MDS codes if CMML criteria are met.
Clinical Validation Requirements
- Persistent monocytosis ≥1 x 10⁹/L
- ≥10% monocytes in peripheral blood
- Dysplasia in one or more myeloid lineages
Code-Specific Risks
- Incorrectly coding as MDS when monocytosis criteria are met.
Coding Notes
- Ensure documentation of monocytosis and dysplasia to support coding.
C93.11 - Chronic myelomonocytic leukemia, in remission
Use when CMML is documented as in remission.
Applicable To
- CMML in remission
Excludes
- Chronic myeloid leukemia (C92.1-)
- Myelodysplastic syndromes (D46.-)
Clinical Validation Requirements
- No circulating blasts
- Bone marrow blasts <5% for ≥4 weeks
Coding Notes
Ensure remission status is clearly documented.
C93.12 - Chronic myelomonocytic leukemia, in relapse
Use when CMML is documented as relapsed.
Applicable To
- Relapsed CMML
Excludes
- Chronic myeloid leukemia (C92.1-)
- Myelodysplastic syndromes (D46.-)
Clinical Validation Requirements
- Recurrent monocytosis
- Increased blasts in peripheral blood
Coding Notes
Ensure relapse status is clearly documented.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Other specified diseases of blood and blood-forming organs
D75.838Differential 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 Chronic Myelomonocytic Leukemia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C93.10.
Impact
Clinical: Misrepresentation of patient's disease status., Regulatory: Non-compliance with coding guidelines., Financial: Potential for claim denial or reduced reimbursement.
Mitigation Strategy
Ensure remission status is clearly documented., Include blast counts in documentation.
Impact
Reimbursement: Incorrect coding may lead to denied claims or reduced reimbursement., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data affecting patient records.
Mitigation Strategy
Ensure monocytosis and dysplasia are documented to support CMML coding.
Impact
Lack of documentation for persistent monocytosis can lead to audit issues.
Mitigation Strategy
Ensure monocytosis is documented in all relevant clinical notes.
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.
