Updated by the Tigertest team. Weighted to the AHIMA CCA Exam Content Outline. Original questions on coding guidelines and concepts; not affiliated with AHIMA.
1. In a Medical and Surgical ICD-10-PCS code, the third character is the:
- A.Approach value
- B.Root operation
- C.Body part
- D.Body system
Answer: B. The seven characters are section, body system, root operation, body part, approach, device and qualifier. The root operation is the objective of the procedure.
2. In the Medical and Surgical section, the sixth character identifies the:
- A.Approach
- B.Body part
- C.Qualifier
- D.Device
Answer: D. The sixth character is the device left in place at the end of the procedure, or Z for no device. The seventh is the qualifier and the fifth is the approach.
3. Why are the letters O and I not used in ICD-10-PCS?
- A.They look like 0 and 1
- B.They stand for Open and Inpatient
- C.They are saved for new codes
- D.They mark deleted values
Answer: A. PCS leaves out O and I so they cannot be confused with the digits 0 and 1. Every character can be a digit or one of the remaining 24 letters.
4. Cutting out or off a portion of a body part, without replacement, is the root operation:
- A.Extraction
- B.Detachment
- C.Excision
- D.Resection
Answer: C. Excision takes out some of a body part. Resection takes out all of a body part, extraction pulls or strips it out by force and detachment cuts off part of an extremity.
5. A breast lesion biopsy is followed in the same session by excision at the same site. Code:
- A.Only the biopsy, diagnostic
- B.The excision as diagnostic
- C.Both procedures
- D.Only the excision
Answer: C. When a diagnostic excision, extraction or drainage (a biopsy) is followed by a more definitive procedure at the same site, both the biopsy and the definitive treatment are coded.
6. Fulguration of a bladder lesion, where nothing is taken out, is coded to:
- A.Destruction
- B.Extirpation
- C.Resection
- D.Excision
Answer: A. Destruction is physical eradication of all or part of a body part by energy, force or a destructive agent, with nothing taken out. Extirpation takes out solid matter such as a stone.
7. Angioplasty that widens a narrowed artery is coded to the root operation:
- A.Supplement
- B.Bypass
- C.Restriction
- D.Dilation
Answer: D. Dilation expands the orifice or lumen of a tubular body part. Bypass changes the route of passage, and restriction partially closes the lumen.
8. Partially closing the lumen of a tubular body part is the root operation:
- A.Bypass
- B.Restriction
- C.Occlusion
- D.Dilation
Answer: B. Restriction partially closes an orifice or lumen. Occlusion closes it completely, as when a vessel is ligated.
9. A hernia repair that reinforces the wall with mesh is coded to the root operation:
- A.Insertion
- B.Supplement
- C.Repair
- D.Replacement
Answer: B. Supplement puts in or on material that reinforces or augments a body part, such as mesh. Replacement is used when the device takes the place or function of the body part.
10. The root operation Repair is used:
- A.Whenever a device is left
- B.Before any other operation
- C.For every suture closure
- D.When no other one fits
Answer: D. Repair restores a body part to its normal structure and function and is the not elsewhere classified root operation, used only when the procedure fits no other root operation.
