Subluxation of unsp interphalangeal joint of finger, init

This code signifies a partial dislocation of an interphalangeal joint in any finger other than the thumb, where the specific joint (proximal or distal) is not documented. The joint surfaces are misaligned but still maintain some contact. This diagnosis is for the initial treatment of the injury.

Use this code when documentation indicates a subluxation of an interphalangeal joint of a finger (excluding the thumb), and the specific joint (e.g., PIP or DIP) is not specified. This is appropriate for the initial encounter for treatment of such an injury, such as in an emergency department or initial office visit.

• Ensure the documentation clearly states "subluxation" and not a complete dislocation.
• Verify that the injury is to a finger other than the thumb; thumb injuries have separate codes.
• Confirm this is the patient's first encounter for this specific injury to use the "A" seventh character.
