M13.851
ICD-10-CMThis code signifies a diagnosis of arthritis affecting the right hip joint that does not fit into more specific categories like osteoarthritis, rheumatoid arthritis, or traumatic arthritis. It encompasses various less common or ill-defined arthritic conditions impacting the right hip. The condition typically presents with pain, stiffness, and reduced range of motion in the affected joint.
Utilize this code when documentation clearly indicates arthritis of the right hip, but the specific type of arthritis is not otherwise classifiable (e.g., "inflammatory arthritis, right hip, not otherwise specified," or "degenerative joint disease, right hip, atypical presentation"). Supporting documentation should specify the laterality (right hip) and confirm an arthritic process without a more precise diagnosis.
