Strain extn musc/fasc/tend r mid finger at wrs/hnd lv, subs

This code signifies a non-traumatic overstretching or tearing of the extensor muscle, its surrounding fascia, or the tendon specifically located in the right middle finger, at the level of the wrist or hand. This injury results from excessive force or repetitive motion, leading to pain, swelling, and impaired finger movement.

Apply this code for follow-up encounters where a patient is receiving active treatment or recovering from a previously diagnosed strain of the right middle finger extensor structures. This includes visits for physical therapy, medication management, or re-evaluation of the healing process after the initial injury.

• Ensure the documentation clearly specifies the right middle finger and the extensor muscle/tendon.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing phase.
• Confirm the injury is a strain (overstretching/tear) and not a rupture or other type of injury.
