Abscess of bursa, unspecified elbow

This code signifies an infection with pus formation within the bursa of an unspecified elbow. It indicates an inflammatory process affecting the fluid-filled sac that cushions the elbow joint, leading to localized collection of purulent material.

Use this code when documentation clearly states an abscess of the bursa in the elbow, but the specific laterality (right or left) is not specified. This diagnosis is typically supported by physical examination findings of a tender, swollen, and possibly erythematous elbow, often with aspiration confirming purulent fluid.

• Ensure documentation explicitly mentions "abscess" of the bursa; mere bursitis without infection should be coded differently.
• Avoid using this code if laterality (right or left elbow) is documented; instead, select the more specific M71.021 or M71.022.
• Consider an additional code for the causative organism if identified and documented (e.g., B95-B97 for bacterial infections).
