Effusion, right hip

This code signifies the presence of an abnormal accumulation of fluid within the synovial joint capsule of the right hip. This fluid buildup, known as effusion, can cause pain, swelling, and restricted range of motion in the affected joint. It is a non-specific finding that can result from various underlying conditions.

Use this code when diagnostic imaging (e.g., ultrasound, MRI, X-ray) or clinical examination confirms the presence of fluid in the right hip joint. Documentation should clearly state "effusion of the right hip" or similar findings. This code is often used as a secondary diagnosis, as the effusion itself is usually a symptom of another condition.

• Always seek to code the underlying cause of the effusion if known and documented (e.g., osteoarthritis, trauma, infection).
• Do not confuse with hemarthrosis (blood in the joint) or pyarthrosis (pus in the joint), which have specific codes.
• Ensure laterality is correctly identified; this code is specific to the right hip.
