Inj extensor musc/fasc/tend thmb at wrs/hnd lv, subs

This code signifies a documented injury to an extensor muscle, fascia, or tendon of the thumb, excluding a strain or rupture, that occurred at the wrist or hand level. This injury is not further specified as a strain or rupture but is an "other specified" type of injury. The "D" suffix indicates that this is a subsequent encounter for care of the injury.

Use this code for follow-up visits or ongoing treatment for a previously diagnosed "other specified" injury to the thumb's extensor structures at the wrist or hand. This includes situations like physical therapy, wound care, or medication management after the initial injury. It is appropriate when the patient is receiving routine care during the healing phase.

• Ensure documentation clearly states an "other specified" injury, not a strain or rupture, and specifies the extensor structures of the thumb.
• Verify the encounter is for subsequent care after the initial treatment of the injury.
• Confirm the injury location is at the wrist or hand level of the thumb.
