Bilateral osteoarthritis resulting from hip dysplasia

This code signifies the presence of degenerative joint disease affecting both hip joints, specifically when the osteoarthritis is a direct consequence of congenital or developmental hip dysplasia. It indicates a secondary form of osteoarthritis where the underlying structural abnormality of the hip joint predisposes it to early and accelerated wear and tear.

Apply this code when documentation clearly states bilateral hip osteoarthritis and explicitly links its etiology to hip dysplasia. This is typically supported by imaging reports (X-rays, MRI) showing dysplastic features alongside osteoarthritic changes, and physician notes detailing the patient's history of hip dysplasia.

• Ensure documentation specifies bilateral involvement; unilateral osteoarthritis due to dysplasia would use a different code.
• Verify the causal link between the osteoarthritis and the hip dysplasia; if the dysplasia is present but not the cause of the osteoarthritis, a different code for primary osteoarthritis may be more appropriate.
• Do not confuse with M16.0 (primary bilateral osteoarthritis of hip) or M16.1 (unilateral osteoarthritis resulting from hip dysplasia).
