Inj intrinsic musc/fasc/tend finger at wrs/hnd lv, subs

This code signifies a subsequent encounter for an injury to an intrinsic muscle, fascia, or tendon of any finger other than the thumb, specifically located at the wrist or hand level. This includes sprains, strains, or tears affecting the small muscles and connective tissues within the hand that control finger movement, excluding the thumb.

Use this code when documenting follow-up care for a patient who previously sustained an injury to an intrinsic muscle, fascia, or tendon of a finger (excluding the thumb) at the wrist or hand level. This applies to encounters for ongoing treatment, rehabilitation, or monitoring of the healing process after the initial injury.

• Ensure the documentation clearly specifies a subsequent encounter for the injury.
• Verify the injury is to an intrinsic muscle, fascia, or tendon, not a major extrinsic tendon.
• Confirm the affected finger is not the thumb and the injury location is at the wrist or hand level.
