Inj extensor musc/fasc/tend l mid finger at forarm lv, subs

This code signifies an injury to the extensor muscle, fascia, or tendon of the left middle finger, specifically located at the forearm level. This injury is not a rupture or laceration, but rather another type of damage such as a strain or sprain. The "D" suffix indicates that this is a subsequent encounter for care after the initial treatment phase.

Apply this code when documenting follow-up care for a patient with a non-rupture/non-laceration injury to the extensor structures of the left middle finger, where the injury site is within the forearm. This includes scenarios like physical therapy, cast changes, or medication refills for a previously diagnosed strain or sprain. It is appropriate for encounters occurring after the initial acute treatment.

• Ensure the injury is to the extensor structures and not the flexor.
• Verify the specific finger (middle) and side (left) are accurately documented.
• Confirm the injury is located at the forearm level and not the hand or wrist.
