Clinical Validation Requirements
- Chondral delamination on imaging
Coding Notes
Document specific cartilage findings to support this code.
M25.859 - Other specified joint disorders, not elsewhere classified
Use when FAI symptoms are present but no specific labral or cartilage damage is documented.
Applicable To
- FAI with joint derangement not otherwise specified
Excludes
- Specific labral or cartilage disorders
Clinical Validation Requirements
- Clinical signs of impingement without imaging confirmation
Coding Notes
Ensure lack of specific findings is documented.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential 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 Femoroacetabular Impingement to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M24.151.
Impact
Clinical: May lead to inappropriate treatment, Regulatory: Non-compliance with documentation standards, Financial: Potential for denied claims
Mitigation Strategy
Always specify FAI type in documentation, Use structured templates for consistency
Impact
Reimbursement: May result in lower reimbursement, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data representation
Mitigation Strategy
Use M24.15- instead
Impact
Lack of imaging confirmation for FAI codes
Mitigation Strategy
Ensure all FAI diagnoses are supported by imaging findings in the record.
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.
