Dislocation of interphalangeal joint of left thumb, init

This code signifies a complete separation of the bones forming the joint within the left thumb, specifically between the phalanges. This injury disrupts the normal alignment and function of the thumb's interphalangeal joint.

Apply this code when documenting a patient's initial presentation for a dislocated interphalangeal joint of the left thumb. This typically occurs following trauma, such as a fall or direct impact, resulting in visible deformity and significant pain.

• Ensure documentation clearly specifies "dislocation" versus a subluxation or sprain.
• Verify the laterality is correctly identified as "left thumb."
• Confirm this is the patient's first encounter for this specific injury, as indicated by the "A" seventh character.
