All questions

Question 1

A patient undergoes a surgical excision of a 1.5 cm malignant skin lesion from the neck. The surgeon performs an intermediate layer closure. The CPT code book indicates that excision codes include simple closure.

Based on CPT surgery guidelines for the Integumentary System, how should this service be coded?

  1. Report the excision code only.
  2. Report the intermediate repair code only.
  3. Report the excision code and the intermediate repair code separately. (correct answer)
  4. Report the excision code with modifier 22 for the increased complexity of the closure.
Explanation: The correct answer is to report both the excision code and the intermediate repair code. The CPT guidelines under 'Excision—Malignant Lesions' and 'Repair (Closure)' state that simple closure is included in the lesion excision. However, if the closure is intermediate or complex, the repair code should be reported separately. Parenthetical notes under the excision codes confirm this by stating 'For intermediate or complex repair, see...'.

Question 2

During a laparoscopic cholecystectomy, the surgeon performs an intraoperative cholangiogram to visualize the bile ducts. The parenthetical note for CPT code 47563 (Laparoscopy, surgical; cholecystectomy with cholangiography) states '(For cholecystectomy only, use 47562).'

According to the parenthetical note and CPT guidelines, what is the correct coding for a laparoscopic cholecystectomy with an intraoperative cholangiogram?

  1. 47562, 74300
  2. 47563 (correct answer)
  3. 47562, 47563
  4. 47563, 74300-26
Explanation: CPT code 47563 describes a laparoscopic cholecystectomy that includes cholangiography. The CPT guidelines and code descriptor bundle these two services into a single code. Reporting the surgical code (47562) and the radiology code (74300) separately would be unbundling. The parenthetical note directs the coder to the correct comprehensive code for the combined procedure.

Question 3

A physician performs an esophagoscopy for a foreign body removal (43194) and a diagnostic upper gastrointestinal endoscopy (43200) during the same encounter. A parenthetical note under 43194 states '(Do not report 43194 in conjunction with 43200-43229, 43232)'.

How should the coder report these services based on the CPT parenthetical instruction?

  1. 43194, 43200-51
  2. 43200
  3. 43194 (correct answer)
  4. 43194, 43200-59
Explanation: The parenthetical note following CPT code 43194 explicitly prohibits reporting it with 43200. The esophagoscopy is the more specific and higher-level procedure in this case. CPT guidelines and NCCI edits consider the diagnostic endoscopy to be a component of the therapeutic procedure when performed in the same session, so only the therapeutic procedure (43194) should be reported.

Question 4

A patient undergoes a total abdominal hysterectomy with bilateral salpingo-oophorectomy. CPT code 58150 describes this combined procedure. The surgeon also performs an appendectomy during the same operative session because the appendix appeared slightly inflamed, but pathology later found it to be normal.

The appendectomy code, 44950, is designated as a 'separate procedure'. Based on CPT guidelines, how should the appendectomy be coded in this scenario?

  1. Report 58150 and 44950-51.
  2. Report 58150 only. (correct answer)
  3. Report 44950 only.
  4. Report 58150 and 44950-59.
Explanation: The CPT guidelines state that a procedure designated as a 'separate procedure' should not be reported when it is carried out through the same incision and is considered an incidental component of a more extensive procedure. Since the appendectomy was performed through the same abdominal incision as the hysterectomy and was not performed for a distinct, pre-diagnosed condition, it is considered incidental and not separately reportable.

Question 5

A cardiologist performs a coronary artery bypass graft using two arterial grafts (e.g., 33534). During the procedure, the cardiologist also harvests the upper extremity artery used for one of the grafts. Add-on code +35600 is for 'Harvest of upper extremity artery, 1 segment, for coronary artery bypass procedure'. A parenthetical note under +35600 states '(List separately in addition to code for primary procedure)'.

How should the harvesting procedure be coded according to CPT guidelines?

  1. Do not report the harvest, as it is included in the main procedure.
  2. Report 35600 as a standalone code.
  3. Report 33534 and +35600. (correct answer)
  4. Report 33534 with modifier 22 to indicate the harvest.
Explanation: The parenthetical note and the + symbol for code 35600 indicate it is an add-on code that must be reported with the primary procedure. The main bypass code (33534) does not include the harvesting of an upper extremity artery. Therefore, both the primary procedure code and the add-on code for the harvest must be reported to fully describe the services performed.

Question 6

A surgeon performs three procedures on a patient during the same operative session. One of the procedure codes is listed in Appendix E of the CPT manual.

What is the significance of a CPT code being listed in Appendix E, and how does it affect coding?

  1. The code is exempt from the use of modifier 51. (correct answer)
  2. The code requires the use of modifier 50 for bilateral procedures.
  3. The code is a new code for the current year.
  4. The code can only be reported by specific specialties.
Explanation: Appendix E in the CPT code book lists codes that are exempt from the use of modifier 51 (Multiple Procedures). These codes are typically add-on codes or procedures that are already valued to not be subject to multiple procedure payment reductions. The guidelines for modifier 51 specify this exemption.

Question 7

A patient presents for a follow-up visit 20 days after undergoing a major surgery with a 90-day global period. The visit is to manage a complication directly related to the surgery.

According to CPT's global surgery guidelines, how should this E/M service be reported?

  1. The E/M service should be reported with modifier 24.
  2. The E/M service should not be reported as it is included in the global package. (correct answer)
  3. The E/M service should be reported with modifier 57.
  4. The E/M service should be reported with modifier 25.
Explanation: The CPT guidelines for the global surgical package state that typical postoperative care is included in the fee for the original procedure. This includes care for complications that do not require a return trip to the operating room. Modifier 24 is used for an unrelated E/M service during the postoperative period, which is not the case here. Therefore, this visit is part of the global package and is not separately billable.

Question 8

A radiologist supervises and interprets a hysterosalpingography. The CPT code book has a code for the complete procedure (58340) and a code for the radiological supervision and interpretation only (74740). The procedure was performed in a hospital setting where the hospital owns the equipment and employs the technician.

Based on CPT guidelines for radiological procedures, what code(s) should the radiologist report?

  1. 58340
  2. 74740 (correct answer)
  3. 58340, 74740
  4. 74740-TC
Explanation: CPT guidelines for radiology specify that when a physician only supervises and interprets a radiological procedure, they should report the 'Radiological Supervision and Interpretation' code. The code for the complete procedure (58340) would be reported by the physician who injected the contrast material. In a hospital setting, the radiologist typically reports only their professional component, which is represented by the S&I code (74740).

Question 9

A patient has a screening colonoscopy, and a polyp is found and removed via snare technique. The CPT code for screening colonoscopy is 45378. The CPT code for colonoscopy with snare polypectomy is 45385.

According to CPT guidelines for endoscopic procedures, how should this encounter be coded?

  1. Report 45378 for the screening.
  2. Report 45385 for the therapeutic procedure. (correct answer)
  3. Report 45378 and 45385-59.
  4. Report 45378 and 45385-51.
Explanation: The CPT guidelines for endoscopies state that when a screening procedure becomes therapeutic (e.g., a polyp is removed), the code for the therapeutic procedure should be reported instead of the screening code. The diagnostic aspect of the procedure is considered integral to the therapeutic procedure. Therefore, only 45385 should be reported.

Question 10

A 9-month-old infant is brought to the pediatrician for a well-child visit. During the visit, the pediatrician administers a DTaP-IPV vaccine via intramuscular injection. The CPT codebook lists codes for the preventive medicine service, the vaccine product, and the vaccine administration.

According to the CPT guidelines in the Medicine section, which codes are necessary to report the complete service?

  1. Report only the preventive medicine E/M code.
  2. Report the preventive medicine E/M code and the vaccine product code.
  3. Report the preventive medicine E/M code, the vaccine product code, and the vaccine administration code. (correct answer)
  4. Report only the vaccine administration code, as it includes the E/M service and product.
Explanation: The CPT guidelines for immunizations are clear that three components should be reported: 1) The appropriate E/M service (in this case, preventive medicine); 2) The vaccine/toxoid product code from 90476-90759; and 3) The vaccine administration code(s) from 90460-90474. Each component represents a distinct part of the overall service provided.

Question 11

A physician performs an E/M service for an established patient in the office. The visit is straightforward in terms of medical decision making, but the physician spends a total of 70 minutes face-to-face with the patient, with more than half of that time spent in counseling and coordinating care regarding the patient's diabetes management and lifestyle modifications.

Based on CPT E/M guidelines for time-based coding when counseling dominates the encounter, how should this service be coded?

  1. Code based only on the key components of history, exam, and medical decision making.
  2. Code based on time, as counseling dominated more than 50% of the face-to-face time. (correct answer)
  3. Code the lowest level E/M since the medical decision making was straightforward.
  4. Time cannot be used as a factor when medical decision making is straightforward.
Explanation: CPT E/M guidelines state that when counseling and/or coordination of care dominates (more than 50%) the face-to-face time with the patient, time may be used as the key factor for selecting the level of service. The physician must document the total time spent and the nature of the counseling or coordination of care. This principle applies regardless of the complexity of medical decision making when counseling dominates the encounter.

Question 12

A patient has a fine needle aspiration (FNA) biopsy of a thyroid nodule performed with ultrasound guidance. The CPT code for the FNA is 10021. The code for ultrasound guidance for needle placement is 76942.

A parenthetical note under 10021 states '(For radiological supervision and interpretation, see 76942, 77002, 77012, 77021)'. How should these services be reported?

  1. Report 10021 only.
  2. Report 76942 only.
  3. Report 10021 and 76942. (correct answer)
  4. Report 10021-22 to include the guidance.
Explanation: The parenthetical note explicitly directs the coder to the appropriate radiological guidance codes to be used in conjunction with the FNA biopsy code. CPT guidelines intend for the biopsy procedure and the imaging guidance to be reported separately, as they represent two distinct services performed by the physician. Code 10021 does not include the work of the ultrasound guidance.

Question 13

A patient undergoes a complete right heart catheterization (93451) and a left heart catheterization with coronary angiography and ventriculography (93458).

The CPT guidelines and parenthetical notes indicate that there are combination codes for when these procedures are performed together. How should this be coded?

  1. 93451, 93458-51
  2. 93458
  3. A single comprehensive code for a combined right and left heart catheterization. (correct answer)
  4. 93451
Explanation: CPT guidelines for cardiac catheterization emphasize using a single, comprehensive code that describes all components of the procedure performed. There are specific codes (e.g., 93460) for combined right and left heart catheterization. Reporting the codes for the right and left heart procedures separately is incorrect and violates the guideline to use the most specific, comprehensive code available.

Question 14

A patient requires a lumbar puncture (spinal tap). The physician performs the procedure and also provides fluoroscopic guidance to ensure proper needle placement.

The parenthetical note for the lumbar puncture code (62270) states, '(For radiological supervision and interpretation, see 77003)'. What is the correct coding?

  1. Report 62270 only, as guidance is always included.
  2. Report 77003 only, as it is the more comprehensive code.
  3. Report 62270 and 77003. (correct answer)
  4. Report 62270 with modifier 22 for the additional work of guidance.
Explanation: The CPT guidelines and the explicit parenthetical note instruct the coder to report the imaging guidance separately. The base code for lumbar puncture (62270) does not include the work or equipment for fluoroscopic guidance. Therefore, both the procedural code and the radiological supervision and interpretation code must be reported to capture the full scope of services provided.

Question 15

A patient is seen for an office consultation (99244). The consultant performs the evaluation and dictates a report, but does not send the report back to the requesting physician.

According to the CPT guidelines for Consultation services, has the requirement for reporting a consultation code been met?

  1. Yes, because the patient was evaluated.
  2. Yes, because the consultant has an opinion.
  3. No, because a written report was not communicated to the requesting physician. (correct answer)
  4. No, because the consultation took place in an office setting.
Explanation: The CPT E/M guidelines define a consultation as a service provided by a physician whose opinion or advice regarding evaluation and/or management of a specific problem is requested by another physician. A key requirement is that the consultant prepares a written report of their findings and communicates it to the requesting provider. Without this communication, the service does not meet the CPT definition of a consultation and should be coded as an office visit.

Question 16

A surgeon performs a complex repair of a 3.0 cm laceration on the cheek and also debrides 15 sq cm of non-viable tissue from the same wound before closing it.

The guidelines for Repair (Closure) state that debridement is considered a separate procedure only when certain criteria are met, such as gross contamination requiring prolonged cleansing. For a clean wound, minor debridement is included. Assuming this was a clean wound, how should this be coded?

  1. Report the complex repair code and the debridement code.
  2. Report only the complex repair code. (correct answer)
  3. Report only the debridement code.
  4. Report the complex repair code with modifier 22.
Explanation: The CPT guidelines under 'Repair (Closure)' state that simple debridement of a wound (e.g., cleaning, removal of small amounts of non-viable tissue) is included in the repair code and is not separately reportable. Significant, separate debridement can be reported, but for a typical laceration requiring closure, the debridement described is considered part of the repair service.

Question 17

A physician performs a new, cutting-edge surgical procedure on the spine for which there is no specific Category I CPT code. However, a Category III code that accurately describes the procedure is available.

According to the CPT guidelines for Category III codes, what is the appropriate way to report this service?

  1. Report the closest Category I CPT code.
  2. Report an unlisted procedure code from the appropriate Category I section.
  3. Report the specific Category III code. (correct answer)
  4. Do not report the service until a Category I code is established.
Explanation: The CPT guidelines clearly state that if a Category III code is available to describe a service or procedure, it must be used instead of an unlisted Category I code. Category III codes are specifically for emerging technologies, services, and procedures to allow for data collection.

Question 18

A surgeon performs a carpal tunnel release (64721). During the same operative session, through the same incision, the surgeon also performs a tenosynovectomy of the flexor tendons of the wrist.

CPT guidelines state that some procedures are integral to a more comprehensive procedure. If the tenosynovectomy is considered an integral part of the standard carpal tunnel release, how should it be coded?

  1. Report 64721 and the code for tenosynovectomy with modifier 59.
  2. Report 64721 only. (correct answer)
  3. Report only the code for the tenosynovectomy.
  4. Report 64721 and the code for tenosynovectomy with modifier 51.
Explanation: According to CPT surgical guidelines and National Correct Coding Initiative (NCCI) edits, a tenosynovectomy performed at the same site and through the same incision as a carpal tunnel release is considered an integral component of the primary procedure. It is not separately reportable. The work is included in the valuation of the carpal tunnel release code.

Question 19

A pathologist examines two separate skin specimens from a patient. The first is a shave biopsy from the right arm, and the second is a punch biopsy from the left leg. Both are sent in separate containers and labeled as such.

Based on the CPT guidelines for Surgical Pathology, how should these services be coded?

  1. Report the surgical pathology code once, as the specimens are from the same patient.
  2. Report the surgical pathology code twice, with each unit representing a separate specimen. (correct answer)
  3. Report the surgical pathology code with modifier 50 for bilateral sites.
  4. Report the surgical pathology code for the more complex specimen only.
Explanation: The guidelines in the Pathology and Laboratory section state that the unit of service for surgical pathology codes is the specimen. A specimen is defined as tissue submitted in a single container. Because two separate specimens from two distinct anatomic sites were submitted in separate containers, the appropriate surgical pathology code (e.g., 88305) should be reported twice (or as one line item with 2 units of service).

Question 20

A physician performs a procedure on a patient. Later the same day, the physician performs a second, distinct procedure on the same patient that is not related to the first. Both are major procedures.

The CPT guidelines for modifiers describe using modifier 79 for an 'Unrelated Procedure or Service by the Same Physician or Other Qualified Health Care Professional During the Postoperative Period.' Is this the correct modifier for this scenario?

  1. Yes, because the procedures are unrelated.
  2. No, modifier 79 is for procedures performed during the postoperative period of another procedure.
  3. No, modifier 59 should be used for distinct procedures performed on the same day. (correct answer)
  4. Yes, it can be used for any second procedure by the same physician.
Explanation: Modifier 79 is specifically for an unrelated procedure performed during the postoperative period of another procedure. Since both procedures are performed on the same day, there is no established postoperative period yet. For unrelated procedures performed on the same day, modifier 59 (Distinct Procedural Service) is the appropriate choice to indicate that the procedures were separate and distinct from each other. The global period begins the day after surgery for major procedures.
