| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C91.10 | Chronic lymphocytic leukemia of B-cell type not having achieved remission | Use when CLL-B-cell type is confirmed and not in remission. |
|
| C92.02 | Acute myeloid leukemia, in relapse | Use when AML is confirmed to be in relapse. |

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 Leukemia
Primary ICD-10-CM Codes for leukemia
Decision Criteria
clinical Criteria
- Presence of lymphocytosis and specific markers
Applicable To
- CLL-B-cell type not in remission
Excludes
- Acute lymphoblastic leukemia
Clinical Validation Requirements
- Lymphocytosis ≥5×10⁹/L
- CD5+/CD23+ markers
Code-Specific Risks
- Misclassification if remission status is not documented
Coding Notes
- Ensure documentation specifies B-cell type and remission status.
C92.02 - Acute myeloid leukemia, in relapse
Use when AML is confirmed to be in relapse.
Applicable To
- AML in relapse
Excludes
- Chronic myeloid leukemia
Clinical Validation Requirements
- Bone marrow biopsy confirming ≥20% blasts
- Presence of FLT3-ITD or NPM1 mutation
Coding Notes
Document specific genetic markers and blast percentage.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential 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 Leukemia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C91.10.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to insufficient documentation.
Mitigation Strategy
Ensure all genetic test results are included in the patient's record.
Impact
Reimbursement: May lead to reduced reimbursement if history codes are used incorrectly., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate representation of patient's current health status.
Mitigation Strategy
Ensure current status is documented and use active codes like C91.10 or C92.02.
Impact
Coding remission status without proper documentation.
Mitigation Strategy
Require bone marrow biopsy results to confirm remission status.
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.
