| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| D47.2 | Monoclonal gammopathy | Use for asymptomatic monoclonal gammopathy without CRAB features. |
|
| G63.1 | Polyneuropathy in neoplastic disease | Use when neuropathy is directly linked to monoclonal gammopathy. |
|
| N28.9 | Disorder of kidney and ureter, unspecified | Use for renal involvement in monoclonal gammopathy. |

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

Coding Notes
- Ensure documentation specifies type and quantity of paraprotein.
G63.1 - Polyneuropathy in neoplastic disease
Use when neuropathy is directly linked to monoclonal gammopathy.
Clinical Validation Requirements
- Nerve conduction studies confirming neuropathy
- Link to paraproteinemia
Coding Notes
Ensure explicit documentation of neuropathy linkage.
N28.9 - Disorder of kidney and ureter, unspecified
Use for renal involvement in monoclonal gammopathy.
Clinical Validation Requirements
- Renal biopsy showing monoclonal deposits
Coding Notes
Ensure renal involvement is documented.
Ancillary Codes

C90.0Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Monoclonal Paraproteinemia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D47.2.
Impact
Clinical: Inadequate clinical assessment., Regulatory: Potential coding errors., Financial: Incorrect reimbursement.
Mitigation Strategy
Always specify paraprotein type and level., Link symptoms to specific paraprotein findings.
Impact
Reimbursement: Incorrect DRG assignment., Compliance: Potential audit trigger., Data Quality: Inaccurate clinical data.
Mitigation Strategy
Use D47.2 + N28.9 unless CRAB criteria are met.
Impact
Coding MGUS as multiple myeloma without CRAB criteria.
Mitigation Strategy
Ensure documentation of CRAB criteria before coding as multiple myeloma.
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.
