What is the ICD-10 code for osteoarthritis of multiple joints?

The ICD-10 code for primary generalized osteoarthritis affecting multiple joints is M15.0. This code is used when osteoarthritis affects three or more joint groups without a secondary cause.

How do you code bilateral knee osteoarthritis?

Bilateral knee osteoarthritis is coded as M17.0 if it is primary. If post-traumatic, use M17.3- with appropriate laterality.

Documentation & Coding Risks

Avoid these common issues when documenting Osteoarthritis Multiple Joints.

Failing to document laterality

Impact

Clinical: Inaccurate treatment planning, Regulatory: Potential for coding audits, Financial: Denied claims due to lack of specificity

Mitigation

Always specify right, left, or bilateral in documentation, Use templates that prompt for laterality

Using unspecified codes like M19.90 when specific codes are available

Impact

Reimbursement: May lead to claim denials or reduced reimbursement, Compliance: Non-compliance with coding guidelines, Data Quality: Decreases accuracy of clinical data

Mitigation

Always document specific joints and laterality to use the most specific code.

Use of unspecified codes

Impact

High risk of audit if unspecified codes are used when specific codes are applicable.

Mitigation

Implement coding audits to ensure specificity in documentation.
