| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D47.2 | Monoclonal gammopathy | Use when MGUS is the primary focus of care and CRAB symptoms are absent. |
|
| C90.0 | Multiple myeloma | Use when CRAB symptoms are present and M-protein is ≥3g/dL. |

Documentation & Coding Risks
Avoid these common issues when documenting Monoclonal Gammopathy.
Documenting MGUS without specifying M-protein level.
Impact
Clinical: Leads to potential misdiagnosis., Regulatory: Non-compliance with coding standards., Financial: May result in claim denials.
Mitigation
Always document specific M-protein levels.
Incorrect sequencing of codes when MGUS is present with renal manifestations.
Impact
Reimbursement: Incorrect sequencing can affect DRG assignment and reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation
Sequence renal condition as primary if it is the focus of care, with D47.2 as secondary.
MGUS coding without CRAB exclusion
Impact
Risk of audits due to insufficient documentation of CRAB exclusion.
Mitigation
Ensure CRAB symptoms are explicitly documented as absent.
