| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C90.00 | Multiple myeloma not having achieved remission | Use when the patient has active multiple myeloma without remission. |
|
| C90.01 | Multiple myeloma in remission | Use when the patient is in remission from multiple myeloma. |
|
| C90.02 | Multiple myeloma in relapse | Use when the patient has relapsed multiple myeloma. |

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 Multiple Myeloma
Primary ICD-10-CM Codes for multiple myeloma
Decision Criteria
clinical Criteria
- Presence of ≥10% clonal plasma cells and CRAB criteria
Applicable To
- Active multiple myeloma
Excludes
- Plasma cell leukemia (C90.1)
Clinical Validation Requirements
- ≥10% clonal plasma cells on bone marrow biopsy
- Presence of CRAB criteria
Code-Specific Risks
- Incorrectly coding as remission when active disease is present
Coding Notes
- Ensure documentation specifies active disease status.
C90.01 - Multiple myeloma in remission
Use when the patient is in remission from multiple myeloma.
Applicable To
- Multiple myeloma in complete remission
Excludes
- Plasma cell leukemia (C90.1)
Clinical Validation Requirements
- Documentation of remission status
Coding Notes
Ensure remission status is clearly documented.
C90.02 - Multiple myeloma in relapse
Use when the patient has relapsed multiple myeloma.
Applicable To
- Recurrent multiple myeloma
Excludes
- Plasma cell leukemia (C90.1)
Clinical Validation Requirements
- Documentation of relapse status
Coding Notes
Ensure relapse status is clearly documented.

D47.2Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Multiple Myeloma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C90.00.
Impact
Clinical: Inaccurate treatment planning, Regulatory: Potential audit issues, Financial: Incorrect reimbursement
Mitigation Strategy
Regular training on documentation standards
Impact
Reimbursement: May affect DRG assignment and reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces accuracy of clinical data.
Mitigation Strategy
Always use C90.00, C90.01, or C90.02 based on disease status.
Impact
Inadequate documentation of remission or relapse status can lead to audits.
Mitigation Strategy
Ensure all clinical notes include clear remission or relapse status.
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.
