Dislocation of unsp interphaln joint of l mid finger, init

This diagnosis code indicates a complete displacement of the bones forming an interphalangeal joint within the left middle finger, where the specific joint (proximal or distal) is not documented. This injury typically results in pain, swelling, and deformity of the affected finger.

Apply this code when documentation confirms a dislocation of an interphalangeal joint in the left middle finger, but the provider does not specify whether it's the proximal interphalangeal (PIP) or distal interphalangeal (DIP) joint. This code is appropriate for the initial treatment of such an injury.

• Ensure the documentation explicitly states "unspecified interphalangeal joint" or lacks specificity regarding PIP vs. DIP.
• Verify the laterality is "left middle finger."
• Confirm this is the initial encounter for treatment of this specific dislocation.
