| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D59.11 | Warm autoimmune hemolytic anemia | Use when documentation specifies warm AIHA with IgG antibodies. |
|
| D59.12 | Cold autoimmune hemolytic anemia | Use when documentation specifies cold agglutinin disease with IgM antibodies. |
|
| D59.13 | Mixed type autoimmune hemolytic anemia | Use when both warm and cold antibodies are documented. |
|
| D59.10 | Autoimmune hemolytic anemia, unspecified | Use when the type of AIHA is not specified in documentation. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Primary ICD-10-CM Codes for autoimmune hemolytic anemia
Decision Criteria
clinical Criteria
- DAT positive for IgG antibodies
Applicable To
- IgG-mediated hemolysis
- Antibodies active at ≥37°C
Clinical Validation Requirements
- Positive DAT for IgG antibodies
- Symptoms like jaundice, fatigue, and splenomegaly
Code-Specific Risks
- Misclassification if antibody type not specified
Coding Notes
- Ensure documentation specifies 'warm' and includes DAT results.
D59.12 - Cold autoimmune hemolytic anemia
Use when documentation specifies cold agglutinin disease with IgM antibodies.
Applicable To
- IgM-mediated hemolysis
- Antibodies active at ≤10°C
Excludes
- Warm AIHA (D59.11)
- Mixed-type AIHA (D59.13)
Clinical Validation Requirements
- Positive DAT for IgM antibodies
- Symptoms like acrocyanosis
Coding Notes
Ensure documentation specifies 'cold' and includes DAT results.
D59.13 - Mixed type autoimmune hemolytic anemia
Use when both warm and cold antibodies are documented.
Applicable To
- Presence of both IgG and IgM antibodies
Excludes
- Warm AIHA (D59.11)
- Cold AIHA (D59.12)
Clinical Validation Requirements
- Positive DAT for both IgG and IgM antibodies
Coding Notes
Ensure documentation specifies both antibody types.
D59.10 - Autoimmune hemolytic anemia, unspecified
Use when the type of AIHA is not specified in documentation.
Applicable To
- AIHA without specified antibody type
Excludes
- Warm AIHA (D59.11)
- Cold AIHA (D59.12)
- Mixed-type AIHA (D59.13)
Clinical Validation Requirements
- General symptoms of hemolytic anemia
Coding Notes
Encourage specificity in documentation to avoid using this code.
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 Autoimmune Hemolytic Anemia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D59.11.
Impact
Clinical: May lead to inappropriate treatment, Regulatory: Non-compliance with coding standards, Financial: Potential for reduced reimbursement
Mitigation Strategy
Educate providers on importance of specifying AIHA type, Implement checklists for documentation
Impact
Reimbursement: May lead to lower reimbursement rates, Compliance: Non-compliance with coding specificity requirements, Data Quality: Decreased accuracy in clinical data
Mitigation Strategy
Use D59.11, D59.12, or D59.13 based on antibody type
Impact
Risk of audits due to unspecified AIHA coding
Mitigation Strategy
Ensure documentation includes specific antibody type and DAT 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.
