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

This code signifies a non-traumatic overstretching or tearing of the extensor muscle, fascia, or tendon specifically affecting the right middle finger. The injury is located at the wrist or hand level, indicating involvement of the structures that extend the middle finger.

Apply this code when documenting an acute injury to the extensor mechanism of the right middle finger, such as from repetitive strain, sudden forceful extension, or an awkward movement. This code is appropriate for the initial treatment of such an injury.

• Ensure the documentation specifies the right middle finger and the extensor mechanism.
• Verify the injury is a strain, not a rupture or laceration, which would require a different code.
• Confirm this is the patient's initial encounter for this specific injury.
