The answer is NOT &#8220;D&#8221;. 8.44_ The following documentation is from the health record of a 22-year-old male patient who received hospital outpatient surgery services. Operative Report: The patient injured his foot using a razor-sharp garden hoe while gardening in his yard at home and severed the superficial branch of the external plantar nerve and the flexor digiti minimi brevis tendon in his left foot. The patient experienced loss of sensation on the outer side of the fifth toe and across the side of the foot, so a neurology consultation was requested, and the patient was taken directly to surgery. Following exploration of the wound and identification of the nerve avulsion, repair of the nerve was undertaken using a nerve graft from the sural nerve. A lateral incision was made on the lateral malleolus of the ankle. The nerve was identified and freed for grafting, and the proximal and distal sural nerve endings were anastomosed. The wound was dissected and the damaged area of the nerve was removed. The innervation of the external digital nerve was restored by suturing the 5-cm graft to the proximal and digital ends of the damaged nerve, using the operating microscope. Tenoplasty was performed on the tendon injury, and the wound was closed in layers. Which of the following ICD-10-CM and CPT code sets is correct?
