Rheumatoid bursitis, left hip

This code signifies inflammation of the bursa surrounding the left hip joint, specifically due to rheumatoid arthritis. It indicates a localized manifestation of systemic rheumatoid disease affecting the synovial sacs that cushion tendons and muscles around the hip.

Apply this code when documentation clearly states rheumatoid bursitis affecting the patient's left hip. This diagnosis is typically supported by clinical examination findings of hip pain, tenderness, and swelling, in a patient with a confirmed diagnosis of rheumatoid arthritis.

• Ensure the documentation specifies "rheumatoid" bursitis, not just general bursitis.
• Verify laterality; this code is specific to the left hip.
• Always code the underlying rheumatoid arthritis (e.g., M05.xx or M06.xx) as the primary diagnosis, with this code as a secondary diagnosis.
