Unilateral osteoarth resulting from hip dysplasia, left hip

This code signifies a degenerative joint disease affecting the left hip, specifically caused by an underlying developmental abnormality of the hip joint (dysplasia). It indicates that the osteoarthritis is present in only one hip and is a direct consequence of the hip's improper formation.

Apply this code when documentation clearly states left hip osteoarthritis is secondary to or a result of hip dysplasia. This is typically seen in adult patients with a history of congenital or developmental hip dysplasia who subsequently develop degenerative changes in the affected joint. Supporting documentation would include imaging reports confirming osteoarthritis and a history or diagnosis of hip dysplasia.

• Ensure documentation specifies "left hip" and explicitly links the osteoarthritis to hip dysplasia.
• Do not use this code for primary osteoarthritis or osteoarthritis due to other secondary causes.
• Consider sequencing this code after a code for the underlying hip dysplasia if it is still an active diagnosis.
