Q: Two root operations are similar in that they both involve cutting or separating a body part only. If the sole objective of the procedure is separating or transecting a body part, the root operation is:
- Release
- Reposition
- Transfer
- Division
A: Division

Q: When coding transplant procedures, this term is used to identify the seventh character (Qualifier) and it means "having to do with individuals or tissues that have identical genes, such as identical twins":

- allogeneic
- zooplastic
- autologous
A: syngeneic

- Transfer
A: Insertion

Q: The root operation used for casting of a nondisplaced fracture is __________________.
- Immobilization (located in the Placement Section)
- Restriction
- Replacement
A: Immobilization (located in the Placement Section)

Q: The root operation(s) used for reduction of a displaced fracture with application of a cast is
_______________________.
- Reposition (for the reduction). The application of a cast in conjunction with the reposition is not coded separately.
- Reduction
- Immobilization
A: Reposition (for the reduction). The application of a cast in conjunction with the reposition is not coded separately.

Q: Bone marrow transplantation is coded using the root operation:
- Transplantation (located in the Medical and Surgical Section)
- Transfusion (located in the Administration Section)
- Immobilization (located in the Placement Section)
- Packing (located in the Placement Section)
A: Transfusion (located in the Administration Section)

Q: The root operation for a pedicle skin graft is ____________, but the root operation for a free skin graft is ___________________.
- Transfer; Replacement
- Replacement; Transfer
A: Transfer; Replacement

Q: If the physician documents that the patient had a cornea transplant from a cadaver donor, the root operation is:
- Replacement
- Transplantation
- Reposition
- Supplement
A: Replacement

Q: In Transfer procedures that involve more than one layer (such as the subcutaneous tissue, fascia and muscle body parts), the body part value represents:
- the deepest tissue layer in the flap
- all of the layers involved in the flap
- the skin layer involved in the flap
- the most superficial layer in the flap
A: the deepest tissue layer in the flap

Q: This root operation involves the partial closing of an orifice or lumen of a tubular body part:
- Occlusion
- Restriction
- Bypass
- Dilation
A: Restriction

Q: When coding vessel embolization procedures, if the objective of the vessel embolization is to completely close the vessel, the root operation assigned is ________________, but if theobjective of the vessel embolization is to narrow the lumen of the vessel, then the root operation assigned is______________.
- Occlusion; Restriction
- Restriction; Occlusion
- Restriction; Dilation
- Closure; Restriction
A: Occlusion; Restriction

Q: A patient is seen for elective sterilization and the physician performs a vasectomy by ligating the vas deferens, then excising a portion of the vas deferens. The root operation is:
- Restriction
- Bypass
- Excision
- Occlusion
A: Excision

Q: A child swallowed a toxic chemical by accident a few months ago. Scar tissue is forming in the esophagus. He has to be taken to his physician to stretch the esophagus and open it up. The root operation is:
- Release
- Dilation
- Manipulation
- Excision
A: Dilation

Q: When a patient has a Dilation and Curettage (D & C) procedure performed, the dilation must be performed first to gain access to the endometrium which can then be scrapped, either for diagnostic or therapeutic purposes. The root operation for this procedure is:
- Extraction
- Dilation
- Excision
- Extirpation
A: Extraction

Q: When a coronary artery bypass procedure involves the use of an internal mammary artery, the device value used for character 6 is "Z" which means "no device" because the internal mammary artery is:
- considered a free graft
- cut and separated from its original source
- loosened on one side and brought around to the blocked coronary artery
- considered a nonautologous tissue substitute
A: loosened on one side and brought around to the blocked coronary artery

- 0WUF4JZ
- 0WUF8KZ
A: 0WUF4JZ

Q: A patient was seen with a malfunctioning pacemaker. It was necessary for the physician to adjust the cardiac pacemaker leads. The root operation for this procedure is:
