Flexion deformity, unspecified elbow

This code signifies a permanent bending or contracture of the elbow joint, limiting its ability to fully extend. It indicates a fixed position of the elbow in flexion, without further specification of the underlying cause or laterality.

Use this code when documentation clearly states "flexion deformity of the elbow" without specifying if it's the right or left elbow, or the etiology. This code is appropriate when the physician's assessment confirms a restricted range of motion due to a fixed flexion at the elbow joint.

• Avoid using this code if laterality (right or left elbow) is documented; instead, use the more specific M21.221 or M21.222.
• Do not use this code for temporary or voluntary flexion; it must represent a fixed, pathological deformity.
• Always look for documentation of the underlying cause of the deformity, as a more specific code may be available.
