Other bilateral secondary osteoarthritis of hip

This code signifies a diagnosis of osteoarthritis affecting both hip joints, where the condition is a consequence of another underlying medical issue or condition, rather than primary (idiopathic) osteoarthritis. It indicates a degenerative joint disease in both hips that developed secondary to factors like trauma, congenital hip abnormalities, metabolic disorders, or inflammatory arthropathies.

Use this code when documentation clearly states "bilateral secondary osteoarthritis of hip" or "osteoarthritis of both hips secondary to [specific underlying condition]". This code is appropriate when the physician explicitly links the hip osteoarthritis to a pre-existing or co-existing condition.

• Ensure the documentation specifies "bilateral" and "secondary" to justify using this code.
• Always code the underlying primary condition first, if known and actively treated, followed by this code.
• Differentiate carefully from primary osteoarthritis (M16.0-M16.2) and unilateral secondary osteoarthritis (M16.4-M16.5).
