1. 0BYM0Z0 Root Operation: Transplantation, Lung, Bilateral (0BYM0Z)

Rationale: Transplantation from donor to recipient is an allogeneic transplant. A single code is assigned because it is a combination code that represents both lungs.

2. 01X50Z4 Root Operation: Transfer, Nerve, Median (01X5)

Rationale: The anterior interosseous nerve does not have its own distinct body part value. ICD-10-PCS Coding Guideline B4.2. states that when a specific branch of a body part does not have its own body part value in PCS, the body part is coded to the closest proximal branch that has a specific body part value. Utilization of the Alphabetic Index indicates that the median nerve is the closest proximal branch for the anterior interosseous nerve.

3. 0XM70ZZ Root Operation: Reattachment, Upper Extremity, Left (0XM70ZZ)

Rationale: Left severed arm has been reattached to the body after traumatic amputation.

4. 0QS906Z Root Operation: Reposition, Femoral Shaft, Left (0QS9)

0QSG0CZ Root Operation: Reposition, Tibia, Right (0QSG)

0QSJ0CZ Root Operation: Reposition, Fibula, Right (0QSJ)

Rationale: ORIF repositions the fracture in its appropriate anatomical position as well as providing stabilization of the fracture with internal fixation. There are separate codes to represent each of the fractures in PCS and should be selected when coding.

5. 0TY10Z0 Root Operation: Transplantation, Kidney, Left (0TY10Z)

Rationale: Donor has been matched to recipient and the left kidney is taken from the donor and transplanted into the recipient.

6. 0KXL0Z6 Root Operation, Transfer, Muscle, Abdomen, Left (0KXL) TRAM (transverse rectus abdominis myocutaneous) flap reconstruction, Pedicled, see Transfer, Muscles (0KX)

Rationale: The root operation for a pedicle flap transfer is Transfer. During a pedicle flap transfer the body part transferred remains connected to its vascular and nervous supply. The qualifier identifies that this is a TRAM pedicle graft.

7. 0PSH34Z Root Operation: Reposition, Radius, Right (0PSH)

0PSK3ZZ Root Operation: Reposition, Ulna, Right (0PSK)

Rationale: Closed reduction and percutaneous pinning of the right radius and closed reduction of the right ulna are represented by separate codes. The closed reduction is performed externally and then the fixation device is placed via a small incision to stabilize the fracture of the radius.

8.  01X64Z5 Root Operation: Transfer, Nerve, Radial (01X6)

Rationale: The endoscopic radial to median nerve transfer is considered a percutaneous endoscopic approach.

9.  0VSC0ZZ Root Operation: Reposition, Testis, Bilateral (0VSC)

Rationale: During this procedure, the testes are moved into the inner thigh to protect them because the scrotum has been damaged in some way. This meets the definition of the root operation Reposition, which is “Moving to its normal location, or other suitable location, all or a portion of a body part.”

10. 08SL0ZZ Root Operation: Reposition, Muscle, Extraocular, Right (08SL)

Rationale: The root operation Reposition is used because the eye muscle is moved to a more posterior position to repair the hypertropia. Utilizing the Alphabetic Index, the body value assigned for the right superior rectus muscle is an extraocular eye muscle, right. This procedure requires an incision in the conjunctiva to access the eye muscles, therefore the approach would be Open.

11. 0LMM0ZZ Root Operation: Reattachment, Tendon, Upper Leg, Left (0LMM)

Rationale: The root operation Reattachment is used to code the repair (reattachment) of the tendon rupture. Utilizing the Body Part Key, the body part value assigned for the left quadriceps is upper leg muscle, left. Based on this designation, the body part assigned for this procedure is upper leg tendon, left. Reminder: Root operation repair is only used when there is not a more specific root operation.
