Flexion deformity, left finger joints

This code describes a permanent bending or contracture of one or more joints in the left finger, preventing full extension. This deformity can result from various underlying conditions, leading to impaired hand function and range of motion.

Apply this code when documentation specifies a flexion deformity affecting any joint of the left finger. This diagnosis is supported by physical examination findings noting limited passive or active extension of the finger joints, often accompanied by a history of trauma, arthritis, or neurological conditions.

• Ensure laterality (left) is clearly documented.
• Distinguish from other finger deformities like boutonnière or swan neck, which have specific codes.
• Code any underlying cause of the deformity, such as arthritis or trauma, as an additional diagnosis.
