clinical Criteria
- Presence of trauma history and radiographic findings
documentation Criteria
- Detailed trauma history and imaging results
Applicable To
- Post-traumatic arthritis of right ankle
Excludes
- Rheumatoid arthritis (M06.87)
Clinical Validation Requirements
- History of trauma to the ankle
- Radiographic evidence of osteophytes or joint space narrowing
Code-Specific Risks
- Incorrectly coding as primary osteoarthritis without trauma history
Coding Notes
- Ensure trauma history is clearly documented to justify post-traumatic classification.
M06.871 - Rheumatoid arthritis, right ankle and foot
Use when rheumatoid arthritis is confirmed by lab tests in the right ankle.
Applicable To
- Rheumatoid arthritis of right ankle
Excludes
- Post-traumatic osteoarthritis (M19.171)
Clinical Validation Requirements
- Positive rheumatoid factor or anti-CCP test
Coding Notes
Ensure lab results are documented to support rheumatoid arthritis diagnosis.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Ankle Arthritis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M19.171.
Impact
Clinical: Inaccurate treatment planning, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials
Mitigation Strategy
Always specify right or left in documentation, Use templates that prompt for laterality
Impact
Reimbursement: May lead to reduced reimbursement due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Decreased accuracy in clinical data.
Mitigation Strategy
Always document and code the specific type of arthritis and laterality.
Impact
Claims for post-traumatic arthritis without documented trauma history.
Mitigation Strategy
Implement mandatory trauma history documentation for related codes.
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.
