Unspecified subluxation of right middle finger, init encntr

This code indicates a partial dislocation of a joint in the right middle finger where the specific joint involved (e.g., MCP, PIP, DIP) is not documented. The injury is acute and represents the first time the patient is being treated for this specific subluxation.

Use this code when documentation clearly states a subluxation of the right middle finger, but the physician does not specify which joint within the finger is affected. It is appropriate for the initial visit for this injury, such as in an emergency department or initial orthopedic consultation.

• Ensure "right middle finger" is explicitly documented; laterality and digit are crucial.
• Only use the "A" seventh character for the initial encounter for active treatment of the injury.
• If the specific joint (e.g., metacarpophalangeal, proximal interphalangeal, distal interphalangeal) is known, a more specific code from the S63.20- category should be used.
