| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| M05.79 | Rheumatoid arthritis with rheumatoid factor of multiple sites without organ or systems involvement | Use when RA is seropositive, affects multiple joints, and there is no organ involvement. |
|
| M06.09 | Rheumatoid arthritis without rheumatoid factor, multiple sites | Use when RA is seronegative and affects multiple joints. |
|
| M06.90 | Rheumatoid arthritis, unspecified, multiple sites | Use when RF status and specific joint details are not documented. |

Primary ICD-10-CM Codes for rheumatoid arthritis involving multiple sites
Decision Criteria
clinical Criteria
- Presence of positive RF and multiple joint involvement without organ issues
Applicable To
- Seropositive rheumatoid arthritis affecting multiple joints
Clinical Validation Requirements
- Positive rheumatoid factor (RF) test
- Anti-CCP antibodies
- Clinical documentation of multiple joint involvement
Code-Specific Risks
- Misclassification if organ involvement is present but not documented
Coding Notes
- Ensure RF status is documented to avoid incorrect coding.
M06.09 - Rheumatoid arthritis without rheumatoid factor, multiple sites
Use when RA is seronegative and affects multiple joints.
Applicable To
- Seronegative rheumatoid arthritis affecting multiple joints
Excludes
- Rheumatoid arthritis with rheumatoid factor (M05.xx)
Clinical Validation Requirements
- Negative rheumatoid factor (RF) test
- Clinical documentation of multiple joint involvement
Coding Notes
Ensure seronegative status is documented to avoid incorrect coding.
M06.90 - Rheumatoid arthritis, unspecified, multiple sites
Use when RF status and specific joint details are not documented.
Applicable To
- Unspecified rheumatoid arthritis affecting multiple joints
Excludes
- Specific seropositive or seronegative RA codes
Clinical Validation Requirements
- Lack of specific RF or anti-CCP test results
Coding Notes
Avoid using this code if specific RF or joint details are available.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Long-term (current) use of other high-risk medications
Z79.6Differential 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 Rheumatoid Arthritis Involving Multiple Sites to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M05.79.
Impact
Clinical: May lead to inappropriate treatment plans., Regulatory: Increases risk of non-compliance with coding standards., Financial: Potential for reduced reimbursement due to unspecified coding.
Mitigation Strategy
Always document specific joints affected, Include laterality and disease activity in notes
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Increases risk of audit due to lack of specificity., Data Quality: Reduces accuracy of clinical data.
Mitigation Strategy
Ensure RF status is documented and use specific codes like M05.79 or M06.09.
Impact
High audit risk due to lack of specificity in RA coding.
Mitigation Strategy
Ensure complete documentation of RF status and joint involvement.
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.
