Anesthesia by surgeon
- 25
- 27
- 52
- 47
Correct Answer

A. 47

Explanation

The numbers 25, 27, and 52 do not have any apparent connection to the phrase "Anesthesia by surgeon." However, the number 47 can be associated with anesthesia as it represents the atomic number of silver, which is commonly used in medical settings. Therefore, 47 is the most logical choice as the correct answer.

- 62
Correct Answer

A. 58

Explanation

The correct answer is 58. This code refers to a staged or related procedure or service performed by the same physician during the postoperative period. This means that the physician is performing an additional procedure or service related to the initial surgery within the designated postoperative period.

- 47
- 81
- 74
- 82
Correct Answer

A. 74

Explanation

This answer is correct because the number 74 represents the code for "discontinued outpatient hospital/ambulatory surgery center (ASC) procedure after administration of anesthesia."

Unrelated procedure or service by the same physician during the postoperative period
- 73
- 79
- 80
- 60
Correct Answer

A. 79

Explanation

During the postoperative period, it is not uncommon for a physician to perform unrelated procedures or services. This means that the physician may provide medical care or perform a procedure that is unrelated to the initial surgery. It is important to note that these unrelated procedures or services should be documented separately and billed accordingly. Therefore, the correct answer in this case is 79, which represents the code for "Unrelated procedure or service by the same physician during the postoperative period."

Modifiers -73 and -74 are most appropriate in:
- Inpatient Hospital only.
- Home Health.
- Outpatient Hospital and Ambulatory Surgery Centers (ASC)
- Emergency Room services.
Correct Answer

A. Outpatient Hospital and Ambulatory Surgery Centers (ASC)

Explanation

Modifiers -73 and -74 are most appropriate in Outpatient Hospital and Ambulatory Surgery Centers (ASC). These modifiers are used to indicate that a procedure was discontinued or terminated due to extenuating circumstances before it was completed. In an outpatient hospital or ASC setting, there may be situations where a procedure needs to be stopped midway due to unforeseen complications or patient intolerance. The use of these modifiers helps in accurately documenting and billing for such situations.

What is the correct order of the following three modifiers:-54, -55, -56?
- Surgery care only, Post-Op, Pre-op.
- Pre-op, Surgery, Post-op.
- Pre-op, Post-op, Surgery.
- The decision for surgery, Pre-op, Post-op.
Correct Answer

A. Surgery care only, Post-Op, Pre-op.

Explanation

The correct order of the three modifiers is Surgery care only, Post-Op, Pre-op. This order makes sense in the context of a surgical procedure. First, the patient receives surgery care only, indicating that they are undergoing the surgery itself. Then, they move on to the post-operative (Post-Op) phase, where they receive care and monitoring after the surgery. Finally, they have the pre-operative (Pre-op) phase, which refers to the preparation and evaluation before the surgery takes place.

Distinct Procedural Services, modifier _____ is:
- 59, Only used on surgical procedure codes.
- 59, Only used to specify separate incisions on an existing site.
- 59, Only used surgeons are involved.
- None of the Above.
Correct Answer

A. None of the Above.

Explanation

The correct answer is "None of the Above" because modifier 59 is not only used on surgical procedure codes, nor is it only used to specify separate incisions on an existing site, nor is it only used when surgeons are involved. Modifier 59 is actually used to indicate that a procedure or service is distinct or independent from other services performed on the same day. It is used to identify procedures that are not normally reported together but may be appropriate under certain circumstances.

- Surgical team, one primary and one assistant surgeon.
- Repeat procedure by the same physician, same procedure billed.
- Assistant surgeon, the assistant is available for the entire operation.
Correct Answer

A. Two surgeons, two are primary.

Explanation

The correct answer is "Two surgeons, two are primary." This answer is supported by the information provided in the given text, which states that there are two surgeons and both of them are primary.

Rate this question:

The reason you used modifiers -76, and -77 is to:
- Explain why the patient returned to the operating room during the post-operative period.
- Comply with CMS compliance guidelines.
- Only to supply information, reimbursement will not be affected.
- Explain why a procedure was duplicated, usually with a report, so you will be reimbursed appropriately.
Correct Answer

A. Explain why a procedure was duplicated, usually with a report, so you will be reimbursed appropriately.

Explanation

The reason for using modifiers -76 and -77 is to explain why a procedure was duplicated, usually with a report, so that the healthcare provider can be reimbursed appropriately. These modifiers indicate that a procedure was repeated or restarted during the post-operative period, and provide the necessary documentation to support the need for reimbursement.

When using modifier -80, the assistant surgeon, the primary surgeon, must use modifier:
- Modifier -81.
- Modifier -66.
- Modifier -62.
- No modifier is necessary for the primary surgeon.
Correct Answer

A. No modifier is necessary for the primary surgeon.

Explanation

When using modifier -80, the assistant surgeon, the primary surgeon does not need to use any modifier. Modifier -80 is used to indicate that an assistant surgeon was present during a surgical procedure. In this case, the primary surgeon does not need to use any modifier because the presence of the assistant surgeon has already been indicated.

Rate this question:

3
14.

The main difference between modifier -80 and modifier -81 is:
- The board certification of the assistant surgeon.
- Amount of time the assistant surgeon spends in the OR.
- -81 is used to indicate the primary surgeon, and -80 is for the assistant.
- -80 is used for the primary surgeon, and -81 for the assistant.
Correct Answer

A. Amount of time the assistant surgeon spends in the OR.

Explanation

The correct answer is "Amount of time the assistant surgeon spends in the OR." This is because modifier -80 is used to indicate that the assistant surgeon provided assistance during a surgical procedure for a specified amount of time, while modifier -81 is used to indicate that the assistant surgeon provided assistance during a surgical procedure for a longer, more extensive period of time. Therefore, the main difference between the two modifiers is the duration of time that the assistant surgeon spends in the operating room.

Billing mistakes because the appropriate outside reference lab modifier was not used could:
- Be corrected if modifier -91 is used.
- Cause confusion but will not affect reimbursement.
- Trigger a Medicare audit for Medicare patients.
- Easily be corrected using modifier -92.
Correct Answer

A. Trigger a Medicare audit for Medicare patients.

Explanation

Billing mistakes that occur because the appropriate outside reference lab modifier was not used can potentially trigger a Medicare audit for Medicare patients. This means that if the incorrect modifier is used or omitted, it may raise concerns and prompt an investigation by Medicare to ensure proper billing practices. This could result in additional scrutiny and potential penalties if the billing errors are found to be significant.

Modifier _______, Repeat Clinical Diagnostic Laboratory Test _________:
- -90 is used when there are testing problems with either the specimen or equipment.
- -91 is used only when it is necessary to obtain subsequent (multiple) reading of a test on the same day.
- -90 is used only it is necessary to obtain subsequent (multiple) reading of a test on the same day.
- -91 is used when there are testing problems with either the specimen or equipment.
Correct Answer

A. -91 is used only when it is necessary to obtain subsequent (multiple) reading of a test on the same day.

Explanation

Modifier -91 is used when it is necessary to obtain subsequent (multiple) readings of a test on the same day. This means that if there is a need to repeat the test multiple times on the same day, the -91 modifier should be used. It is not used for testing problems with the specimen or equipment, which is indicated by the -90 modifier. Therefore, the correct answer is that -91 is used only when it is necessary to obtain subsequent (multiple) readings of a test on the same day.

- -56
- -52
- -50
- -57
Correct Answer

A. -57

Explanation

Modifier -57 is appended to the service performed in this scenario. This modifier is used to indicate that the decision to perform a major surgery was made during an evaluation and management service. It signifies that the surgery was the result of a separate and distinct service provided on the same day.

- -78
- -79
Correct Answer

A. -79

Explanation

Modifier -79 is used to indicate an unrelated procedure performed by the same physician during the postoperative period.

- -54
- -66
- -59
- -62
Correct Answer

A. -62

Explanation

When two surgeons work together as primary surgeons performing distinct parts of a single reportable procedure, each surgeon should report his/her distinct operative work by adding modifier -62. This modifier indicates that two surgeons worked together as primary surgeons and performed separate portions of the procedure. Modifier -54 is used when a surgeon provides only the preoperative or postoperative management. Modifier -66 is used when two surgeons work together as primary surgeons and perform the same procedure on the same patient. Modifier -59 is used to indicate a distinct procedural service.

- Never used with MOD-50.
- HCPCS modifiers.

A. All of the above are correct.

Explanation

The correct answer is that all of the above statements are correct. The modifiers -RT and -LT are used to indicate right and left sides respectively. They are never used with MOD-50. These modifiers are commonly used in HCPCS coding to specify the side of the body or the direction of a procedure. Therefore, all of the statements in the question are true.

- Insurance companies are required by the AMA to recognize all valid CPT modifiers.
Correct Answer

A. MOD-63, MOD-53, MOD-54, MOD-55, MOD-56.

Explanation

The group of modifiers MOD-63, MOD-53, MOD-54, MOD-55, and MOD-56 are most likely not to be recognized by insurance carriers. This is because these modifiers are not commonly used or recognized by insurance companies. MOD-63 is used for procedures performed on infants less than 4 kg, MOD-53 is used for discontinued procedures, MOD-54 is used for surgical care only, MOD-55 is used for postoperative management only, and MOD-56 is used for preoperative management only. Insurance carriers may not have specific reimbursement policies or guidelines for these modifiers, leading to potential denials or non-recognition.

- In primary care.
- By two different physicians, on separate claims.
- To indicate whether the operation was on the left or right side of the body.
Correct Answer

A. By two different physicians, on separate claims.

Explanation

The correct answer is "By two different physicians, on separate claims." This is because modifiers -54 and -55 are typically used to indicate that a surgical procedure was performed by two different physicians, each billing for their own services on separate claims. This allows for the appropriate reimbursement and documentation of each physician's involvement in the procedure.

Modifier -TC means:
- Terminal Case (patient is dying)
- Use this only for the Interpretation and Report.
- Technical Component.
- Time Code (This indicates the patient's heart stopped during the procedure)
Correct Answer

A. Technical Component.

Explanation

The modifier -TC stands for Technical Component. This modifier is used to indicate that a specific service or procedure was performed as part of the technical component, which includes the equipment, supplies, and personnel necessary to perform the service. This modifier is typically used in medical billing and coding to differentiate between the professional component (PC) and the technical component (TC) of a service. The TC modifier is used when the technical component is billed separately from the professional component.

You can / cannot use modifiers on HCPCS codes.
- You can.
- You cannot.
- You could before 2004 but no longer.
- You can but for local codes only.
Correct Answer

A. You can.

Explanation

Modifiers can be used on HCPCS codes. Modifiers are two-digit codes that provide additional information about the service or procedure being billed. They are used to indicate that a service or procedure has been altered in some way but has not changed in its definition. Modifiers can be used to indicate multiple procedures, bilateral procedures, or to provide more specific information about the service or procedure being performed. Therefore, it is possible to use modifiers on HCPCS codes.

- Unusual anesthesia, would not; accupuncture.
- Surgical assistant; would ; nurse anesthesist.
Correct Answer

A. Unusual anesthesia, would not; accupuncture.

Explanation

The modifier -23 would not be appropriate for the use of acupuncture. The modifier -23 is used for unusual anesthesia services, which typically involve the use of anesthesia techniques or agents that are not commonly used in the routine anesthesia care. Acupuncture does not involve the use of anesthesia, so the modifier -23 would not be applicable in this case.

Modifier -24 should always be used with:
- Surgical CPT codes.
- E & M codes.
- Anesthesia CPT codes.
- Radiology codes.
Correct Answer

A. E & M codes.

Explanation

Modifier -24 should always be used with E & M codes. This modifier is used to indicate that a significant and separately identifiable evaluation and management service was provided by the same physician on the day before a major surgical procedure. It is used to distinguish the E & M service from the surgical procedure and ensure appropriate reimbursement for both services.

Rate this question:

31.

Modifier -25 is:
- The unusual service modifier.
- Used for the initial evaluation of a problem for which a procedure is performed.
- Never used on E & M procedures.
- None of the above.
Correct Answer

A. Used for the initial evaluation of a problem for which a procedure is performed.

Explanation

Modifier -25 is used for the initial evaluation of a problem for which a procedure is performed. This modifier is added to the evaluation and management (E&M) code to indicate that a significant, separately identifiable evaluation and management service was provided on the same day as a procedure. This allows for the reimbursement of both the procedure and the evaluation and management service. It is important to note that modifier -25 should not be used on E&M procedures, as it is specifically intended for procedures performed in addition to an evaluation and management service.
