Osteoarthritis, Hip
Noninflammatory degenerative disease of the hip joint which usually appears in late middle or old age. It is characterized by growth or maturational disturbances in the femoral neck and head, as well as acetabular dysplasia. A dominant symptom is pain on weight-bearing or motion.
About the M16 Code Range
Hip osteoarthritis is a degenerative joint disease that is not inflammatory. Pain with weight-bearing or movement is a main symptom.
The subdivisions distinguish primary osteoarthritis (M16.0 and M16.1), osteoarthritis resulting from hip dysplasia (M16.2 and M16.3), and osteoarthritis following trauma (M16.4 and M16.5). Each group separates both hips from one hip. The unilateral primary, dysplasia-related, and post-traumatic groups further identify the right hip, left hip, or an unspecified hip. M16.6 and M16.7 distinguish other secondary osteoarthritis in both hips from one hip. M16.9 leaves the hip osteoarthritis unspecified.
