| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D89.0 | Polyclonal hypergammaglobulinemia | Use when polyclonal hypergammaglobulinemia is confirmed by laboratory tests. |
|
| D89.2 | Hypergammaglobulinemia, unspecified | Use when hypergammaglobulinemia is present but not further specified. |

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 Hypergammaglobulinemia
Primary ICD-10-CM Codes for hypergammaglobulinemia
Decision Criteria
clinical Criteria
- Polyclonal pattern on SPEP
documentation Criteria
- Explicit mention of polyclonal hypergammaglobulinemia
Applicable To
- Waldenstrom's hypergammaglobulinemic purpura
Clinical Validation Requirements
- Polyclonal gammopathy confirmed by serum protein electrophoresis (SPEP)
- Elevated IgG, IgA, IgM levels
Code-Specific Risks
- Misclassification if monoclonal pattern is present
Coding Notes
- Ensure documentation specifies polyclonal nature.
D89.2 - Hypergammaglobulinemia, unspecified
Use when hypergammaglobulinemia is present but not further specified.
Excludes
- Polyclonal hypergammaglobulinemia (D89.0)
Clinical Validation Requirements
- Elevated gamma globulins without specific pattern
Coding Notes
Use only when no specific pattern is documented.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

R59.9Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Hypergammaglobulinemia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D89.0.
Impact
Clinical: Misdiagnosis risk, Regulatory: Non-compliance with coding standards, Financial: Potential reimbursement issues
Mitigation Strategy
Ensure lab results are reviewed, Clarify documentation with providers
Impact
Reimbursement: Incorrect DRG assignment may occur., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Verify SPEP results to confirm polyclonal pattern before coding.
Impact
Failure to document specific pattern can lead to audit discrepancies.
Mitigation Strategy
Implement mandatory SPEP result inclusion in records.
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.
