Applicable To
- Primary osteoarthritis of right knee
Excludes
- Secondary osteoarthritis of right knee (M17.31)
Clinical Validation Requirements
- Imaging showing joint space narrowing
- Clinical history of chronic knee pain
Coding Notes
Ensure imaging and clinical history support the diagnosis.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Right Knee Arthroplasty to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Z96.651.
Impact
Clinical: May lead to inappropriate treatment plans., Regulatory: Fails to meet documentation standards., Financial: Could result in claim denials.
Mitigation Strategy
Document specific pain characteristics and related findings.
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data for clinical and research purposes.
Mitigation Strategy
Always use Z96.651 for right knee when laterality is known.
Impact
Using unspecified codes when laterality is documented.
Mitigation Strategy
Implement checks to ensure laterality is documented and coded correctly.
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.
