Rheumatoid myopathy with rheumatoid arthritis of right hip

This code signifies a muscular disorder directly resulting from rheumatoid arthritis, specifically affecting the right hip. It indicates the presence of both rheumatoid myopathy and the inflammatory joint disease in this particular anatomical site.

This code is appropriate when documentation clearly states a diagnosis of rheumatoid myopathy in a patient with confirmed rheumatoid arthritis, with the hip joint on the right side being the affected area. Supporting documentation should include physician notes detailing the myopathy's association with the patient's rheumatoid arthritis and its localization to the right hip.

• Ensure documentation explicitly links the myopathy to rheumatoid arthritis and specifies the right hip.
• Do not use this code for myopathy due to other causes or for rheumatoid arthritis without documented myopathy.
• Consider sequencing this code after the primary rheumatoid arthritis code if the myopathy is a manifestation.
