Fx unsp phalanx of l mid finger, subs for fx w delay heal

This code signifies a fracture of an unknown phalanx (bone segment) in the left middle finger that is not healing as expected. It indicates that the patient is presenting for follow-up care for this specific injury, and the healing process is prolonged or stalled.

This code is appropriate for encounters where a patient is being treated for a left middle finger phalanx fracture that has not united within the expected timeframe. This includes follow-up visits for cast changes, physical therapy, or surgical intervention aimed at addressing the delayed healing.

• Ensure documentation clearly specifies "delayed healing" for the fracture.
• Verify the laterality (left) and specific digit (middle finger) are documented.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
