Subluxation of unsp interphaln joint of l mid finger, subs

This code describes a partial dislocation of an interphalangeal joint within the left middle finger, where the joint surfaces are no longer in complete alignment but remain in partial contact. This specific code is used for encounters following the initial treatment of the injury, indicating ongoing care or follow-up. The exact interphalangeal joint (proximal or distal) is not specified.

Apply this code when a patient presents for follow-up care, rehabilitation, or monitoring of a previously diagnosed subluxation of an unspecified interphalangeal joint of the left middle finger. This includes situations where the patient is receiving physical therapy, undergoing repeat imaging, or being assessed for healing progress after the initial injury.

• Ensure the documentation clearly indicates a "subsequent encounter" for the injury.
• Verify the injury is to the left middle finger and specifically an interphalangeal joint.
• If the specific interphalangeal joint (PIP or DIP) is known, a more specific code should be sought.
