| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D72.820 | Symptomatic lymphocytosis | Use when lymphocytosis is symptomatic and confirmed by lab tests. |

| C91.10 | Chronic lymphocytic leukemia of B-cell type, not having achieved remission | Use when lymphocytosis is due to CLL and confirmed by flow cytometry. |

Code-Specific Risks
- Incorrect use without documented symptoms
Coding Notes
- Ensure symptoms are documented to justify symptomatic coding.
C91.10 - Chronic lymphocytic leukemia of B-cell type, not having achieved remission
Use when lymphocytosis is due to CLL and confirmed by flow cytometry.
Applicable To
- CLL with lymphocytosis
Excludes
- Lymphocytosis without leukemia
Clinical Validation Requirements
- Flow cytometry confirming CD5+/CD23+ B-cells
Coding Notes
Ensure CLL diagnosis is supported by lab results.

R59.9Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Lymphocytosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D72.820.
Impact
Clinical: Misrepresentation of patient's clinical status., Regulatory: Non-compliance with ICD-10 coding rules., Financial: Potential claim denials.
Mitigation Strategy
Verify symptom documentation before coding, Educate staff on coding guidelines
Impact
Reimbursement: Potential denial of claims due to lack of symptom documentation., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure symptoms are documented in the medical record.
Impact
Risk of audits for using symptomatic codes without documentation.
Mitigation Strategy
Ensure thorough documentation of symptoms and lab results.
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.
