| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C83.00 | Small cell B-cell lymphoma, unspecified site | Use when SLL is confirmed in lymph nodes or tissue without blood involvement. |
|
| C91.10 | Chronic lymphocytic leukemia of B-cell type not in remission | Use when CLL is confirmed in blood or bone marrow. |

Primary ICD-10-CM Codes for small lymphocytic lymphoma
Decision Criteria
clinical Criteria
- Biopsy confirms SLL in lymph nodes.
coding Criteria
- No concurrent blood involvement.
Applicable To
- Small lymphocytic lymphoma
Excludes
- Chronic lymphocytic leukemia (C91.1-)
Clinical Validation Requirements
- Lymph node biopsy showing CD5+/CD23+ lymphocytes
- No peripheral blood/bone marrow involvement
Code-Specific Risks
- Misclassification with CLL if blood involvement is not ruled out.
Coding Notes
- Ensure documentation specifies lymph node involvement to avoid confusion with CLL.
C91.10 - Chronic lymphocytic leukemia of B-cell type not in remission
Use when CLL is confirmed in blood or bone marrow.
Applicable To
- Chronic lymphocytic leukemia
Excludes
- Small lymphocytic lymphoma (C83.0-)
Clinical Validation Requirements
- Absolute lymphocytosis (>5×10⁹/L)
- Bone marrow infiltration >30%
Coding Notes
Ensure documentation specifies blood or bone marrow involvement to avoid confusion with SLL.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Small Lymphocytic Lymphoma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C83.00.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with coding guidelines., Financial: Potential claim denials or payment delays.
Mitigation Strategy
Ensure complete documentation of diagnostic tests., Regular training on documentation standards.
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Violates ICD-10 Excludes1 notes., Data Quality: Leads to inaccurate clinical data representation.
Mitigation Strategy
Code only based on the primary site of disease involvement.
Impact
Incorrect coding of SLL vs. CLL based on site documentation.
Mitigation Strategy
Implement regular audits and training on site-specific documentation.
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.
