| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C90.01 | Multiple myeloma in remission | Use when the patient is in remission but the disease is still considered active. |

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting History of Multiple Myeloma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C90.01.
Impact
Clinical: Misinterpretation of patient's current health status., Regulatory: Potential audit issues., Financial: Incorrect billing and reimbursement.
Mitigation Strategy
Regular training on documentation standards.
Impact
Reimbursement: Incorrect DRG assignment leading to lower reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate patient records affecting treatment decisions.
Mitigation Strategy
Use C90.01 for remission cases.
Impact
Incorrect use of history codes for remission cases.
Mitigation Strategy
Regular audits and coder education.
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.
