Compare key differences between these codes to ensure accurate selection
| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D83.0 | Common variable immunodeficiency with predominant B-cell abnormalities | Use when B-cell abnormalities are documented with specific lab findings. |
|
| D83.9 | Common variable immunodeficiency, unspecified | Use when lab confirmation exists but subtype is unclear. |

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 Common Variable Immunodeficiency
Primary ICD-10-CM Codes for common variable immunodeficiency
Decision Criteria
clinical Criteria
- Documented B-cell dysfunction and poor vaccine response
Applicable To
- B-cell dysfunction
- Low IgG/IgA/IgM levels
- Poor vaccine response
Excludes
- Secondary immunodeficiency (D84.9)
Clinical Validation Requirements
- IgG < 400 mg/dL
- Absent pneumococcal antibody titers post-vaccination
- CD19+ B cells < 2% of lymphocytes
Code-Specific Risks
- Incorrect use without documented B-cell studies
Coding Notes
- Ensure documentation of specific lab values and vaccine responses.
D83.9 - Common variable immunodeficiency, unspecified
Use when lab confirmation exists but subtype is unclear.
Applicable To
- Unspecified hypogammaglobulinemia
Excludes
- Specific B-cell or T-cell abnormalities (D83.0, D83.1)
Clinical Validation Requirements
- Confirmed hypogammaglobulinemia without specific subtype
Coding Notes
Use only when specific subtype cannot be determined.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Z00.6Differential 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 Common Variable Immunodeficiency to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D83.0.
Impact
Clinical: Inaccurate diagnosis, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials
Mitigation Strategy
Ensure lab results are included in documentation, Verify vaccine response is recorded
Impact
Reimbursement: Potential denial of claims due to lack of specificity, Compliance: Increased risk of audit, Data Quality: Decreased accuracy in patient records
Mitigation Strategy
Ensure lab results and clinical findings are documented to justify unspecified code.
Impact
Using D83.9 without proper documentation.
Mitigation Strategy
Ensure all relevant lab and clinical data are documented.
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.
