Question 440
A localized gastric neoplasm is treated by resecting only a portion of stomach with reconstruction. What intervention should be recognized from this operative detail?
- Gastrostomy tube removal
- Partial gastrectomy
- Surgical jejunostomy tube placement
- Established gastrostomy tube exchange
Explanation
Correct Answer
B:Partial gastrectomy removes a gastric segment while leaving remaining stomach tissue. This differs from tube management or full total gastric removal.
Incorrect Answers
A:Removal is not equivalent to initial placement or exchange; any distinct closure procedure must be supported by what the physician actually performs; to select this alternative the report would need withdrawal of no-longer-needed gastric tube, whereas it identifies removal of a segment of stomach.
C:The Surgical jejunostomy tube placement choice presumes creation of a small-bowel feeding access rather than exchange, removal, or new placement of a gastric tube; the record instead establishes removal of a segment of stomach, making that alternative an inaccurate description.
D:Exchange uses established access rather than creating a new gastrostomy; whether endoscopic or fluoroscopic guidance is performed affects reporting details; the controlling finding is removal of a segment of stomach, which is distinct from replacement through mature gastrostomy tract.
Question 441
Laser energy vaporizes obstructing prostatic tissue endoscopically without a conventional resection loop. Which choice fits the operative site and technique described?
- Transurethral prostate resection
- Laser vaporization of prostate
- Radical prostatectomy
- Prostatic cryoablation
Explanation
Correct Answer
B:Laser ablation reduces prostate bulk by energy rather than standard tissue resection. The actual laser modality determines available codes.
Incorrect Answers
A:TURP removes tissue from inside the gland through the urethra; it is not complete removal of the prostate for cancer; to select this alternative the report would need transurethral shaving of prostatic obstructing tissue, whereas it identifies endoscopic laser destruction of benign prostate tissue.
C:Radical prostatectomy excises the organ for cancer and may include additional seminal-vesicle or nodal work; it differs from endoscopic debulking of benign enlargement; the distinction is the record’s endoscopic laser destruction of benign prostate tissue versus the alternative of total oncologic removal of prostate.
D:Prostatic cryoablation refers to intentional freezing of prostate tissue rather than needle biopsy, transurethral resection, vaporization, or radical excision, but the documented clinical work is endoscopic laser destruction of benign prostate tissue; choosing it would misclassify the documented encounter.
Question 442
A programmable pump and spinal catheter are implanted for direct delivery of analgesic medication. Which of these operative services matches the completed work?
- Implanted intrathecal medication pump
- Revision of implanted spinal-stimulator lead
- Permanent spinal cord stimulator implant
- Spinal cord stimulator trial lead
Explanation
Correct Answer
A:Intrathecal infusion uses a reservoir and catheter to deliver medication near the spinal cord. It is different from electrical stimulation.
Incorrect Answers
B:The distinguishing evidence for Revision of implanted spinal-stimulator lead would be repositioning of an existing indwelling stimulation lead without placing a new trial system or replacing the generator; the described patient or procedure has implantable pump delivering drug to intrathecal space, not those features.
C:Permanent neuromodulation provides an implanted generator and leads; configuration and implant details determine code selection, beyond temporary percutaneous testing; the scenario instead describes implantable pump delivering drug to intrathecal space, without demonstrating lasting stimulator generator with epidural leads.
D:Trial stimulation assesses benefit before permanent implantation; temporary leads are not equivalent to an implanted pulse-generator system; the distinction is the record’s implantable pump delivering drug to intrathecal space versus the alternative of temporary epidural neuromodulation electrode placement.
Question 443
An ICU patient receives one anteroposterior portable chest image to check a line tip. Which imaging choice accurately represents the acquisition?
- Complete lumbar spine radiographic series
- Single-view portable chest radiography
- Single-view abdominal radiograph
- Two-view chest radiography
Explanation
Correct Answer
B:A one-projection chest examination differs from a two-view study, regardless of why it was ordered. The interpreter must report the exam actually performed.
Incorrect Answers
A:Spine radiography code selection depends on the named region and views performed; do not assume a complete series when only limited projections exist; the operative or visit note documents single AP bedside chest image instead of documented complete multi-projection lumbar series.
C:Single-view abdominal radiograph is supported by documentation of plain-film imaging of the abdomen rather than focused chest, ribs, or lumbar spine; here the decisive finding is single AP bedside chest image; the defining work for this distractor is absent.
D:Two orthogonal chest projections provide anatomic assessment beyond a single frontal film; the number of views actually obtained determines the appropriate radiography category; to select this alternative the report would need frontal and lateral chest x-ray views, whereas it identifies single AP bedside chest image.
Question 444
An excised colonic polyp is processed into paraffin sections and examined microscopically. How should the assay or procedure be identified?
- Surgical pathology tissue examination
- Intraoperative frozen-section consultation
- Flow-cytometric immunophenotyping
- Fine-needle aspiration cytology
Explanation
Correct Answer
A:Surgical pathology evaluates tissue architecture in a submitted specimen, with level based on specimen type and complexity. It differs from cytology of loose cells.
Incorrect Answers
B:Frozen sections provide rapid intraoperative diagnostic guidance; they are distinct from routine permanent-section histology and require documented consultation; to select this alternative the report would need immediate intraoperative frozen tissue interpretation, whereas it identifies fixed excised tissue examined histologically.
C:Selecting Flow-cytometric immunophenotyping would require analysis of cellular surface marker expression rather than cytology, histologic tissue examination, or frozen-section consultation; the actual document states fixed excised tissue examined histologically, which distinguishes the correct choice.
D:FNA cytology assesses cellular material acquired by needle, rather than intact histologic tissue cores; sampling procedure and professional interpretation may have distinct codes; the reported work involves fixed excised tissue examined histologically and does not establish microscopic assessment of aspirated cells.
Question 445
A patient performs forced expiration maneuvers to measure airflow and forced vital capacity. How should this documented therapeutic service be identified?
- Bronchial provocation challenge
- Lung volume measurement
- Baseline spirometry
- Bronchodilator responsiveness study
Explanation
Correct Answer
C:Spirometry evaluates dynamic airway flows and volumes, including FEV1 and FVC. It does not directly measure diffusing capacity or residual lung volume.
Incorrect Answers
A:The required element for Bronchial provocation challenge is induced airway responsiveness testing rather than routine spirometry, postbronchodilator response, lung volumes, or diffusing capacity; what is described is forced expiratory flow-volume measurement, without evidence for the alternative feature.
B:Lung volume assessment evaluates capacities not directly determined by simple forced expiratory spirometry; it helps distinguish restriction and air trapping; this clinical evidence establishes forced expiratory flow-volume measurement, not measurement of static lung volume capacities.
D:Reversibility testing compares lung function before and after therapy; it is more than a single baseline spirometry reading; paired lung function measurements before and after bronchodilator is not recorded; the evidence points to forced expiratory flow-volume measurement.
Question 446
The responsible clinician evaluates a resident on initial admission to a skilled nursing facility. Which E/M reporting approach is consistent with this documentation?
- Emergency department evaluation in a hospital
- Subsequent nursing facility care
- Initial nursing facility care
- Home or residence E/M
Explanation
Correct Answer
C:Nursing facility initial care uses a setting-specific E/M family. A hospital subsequent-care code does not reflect the location and service type.
Incorrect Answers
A:The distinguishing evidence for Emergency department evaluation in a hospital would be hospital emergency-setting encounter rather than home, nursing facility, or nursing facility discharge; the described patient or procedure has first physician evaluation following nursing facility admission, not those features.
B:Subsequent nursing facility care captures later medically necessary management, not a new initial admission examination each day; later facility visit during same nursing residence is not recorded; the evidence points to first physician evaluation following nursing facility admission.
D:Home/residence E/M codes reflect place of service and service characteristics; they are not automatically office codes because the clinician brought a laptop; the controlling finding is first physician evaluation following nursing facility admission, which is distinct from professional medical evaluation in private residence.
Question 447
Base and time units are converted to a monetary allowance using the relevant payer or locality factor. How should this anesthesia service be categorized?
- Anesthesia time-unit component
- Physical-status adjustment
- Postoperative hospital room charge
- Anesthesia payment conversion factor
Explanation
Correct Answer
D:A conversion factor translates unit totals into a payment amount under the applicable schedule. It is not a new unit of surgical time or the physical-status modifier.
Incorrect Answers
A:Time units represent actual qualifying intraservice minutes and may be calculated using the payer's unit interval; do not include unrelated preoperative or recovery time; qualifying minutes converted by payer interval is not recorded; the evidence points to rate applied to anesthesia unit total.
B:Physical status describes patient systemic risk, and whether it affects payment varies by payer; the modifier cannot replace the operative anesthesia code or documented time; the scenario instead describes rate applied to anesthesia unit total, without demonstrating payer-recognized physical status adjustment.
C:This alternative, Postoperative hospital room charge, concerns facility room or recovery charge distinct from anesthesia base units, time units, physical-status adjustments, or conversion factor; the alternative is not supported by the documented rate applied to anesthesia unit total.
Question 448
A facial lesion leaves a 4-square-centimeter primary defect. The surgeon designs a rotation flap that creates a 6-square-centimeter secondary defect, and both areas are documented. What area basis is generally used to select an adjacent-tissue-transfer size category?
- A linear 10-centimeter wound-repair length
- Primary defect area alone, 4 square centimeters
- Combined primary and secondary defect area of 10 square centimeters
- Secondary flap defect alone, 6 square centimeters
Explanation
Correct Answer
C:Adjacent tissue transfer size is generally based on total area of primary and secondary defects, using the applicable location category and current code instructions.
Incorrect Answers
A:Square-centimeter flap area is a different measurement from linear wound-closure length; adding two areas does not produce a length in centimeters.
B:Using only the original wound omits the secondary defect created to mobilize the local flap and understates the total transferred defect area.
D:The secondary defect is not the entire coded area. The primary wound also contributes to total area under adjacent transfer sizing conventions.
Question 449
Sensory loss and weakness are attributed to disease or damage of peripheral nerves. Which term most precisely names the finding?
- Neuropathy
- Neuroplasty
- Neuritis
- Paresthesia
Explanation
Correct Answer
A:Neuropathy indicates a pathologic disturbance in nerve function. It can include sensory, motor, or autonomic deficits and is broader than nerve pain alone.
Incorrect Answers
B:The -plasty ending signifies a reconstructive or repair procedure; A surgical intervention is different from terminology describing pain, inflammation, or neuropathic symptoms; the controlling finding is dysfunction of peripheral nerve tissue, which is distinct from operative repair or reconstruction of a nerve.
C:The ending -itis conveys inflammation of the affected structure; the question is about an inflammatory nerve condition, not simply pain or operative repair; the chart records dysfunction of peripheral nerve tissue rather than inflammation of a nerve.
D:Although Paresthesia may sound adjacent, it denotes an abnormal tingling or prickling sensation instead of nerve inflammation, disease, surgery, or pain; this record documents dysfunction of peripheral nerve tissue, which is distinct from that alternative.
Question 450
A crescent-shaped fibrocartilage structure in the knee distributes load between femur and tibia. What anatomical term correctly names this site?
- Tendon
- Synovial membrane
- Articular cartilage
- Meniscus
Explanation
Correct Answer
D:Knee menisci improve load distribution and joint congruity. They differ from the hyaline cartilage coating the bony articular surfaces.
Incorrect Answers
A:Tendons transmit muscular force to bones; this differs from ligamentous stabilization between bones or the articular cushioning of cartilage; the documented detail of semilunar fibrocartilage within the knee prevents classifying it as attachment of muscle to bone.
B:Synovial membrane reflects the joint-lining tissue that produces synovial fluid, distinct from tendon, ligament, cartilage, or meniscus, whereas the clinical note identifies semilunar fibrocartilage within the knee; the different evidence changes the classification.
C:Joint cartilage provides a low-friction weight-bearing surface; it is distinct from ligaments outside the joint and meniscal fibrocartilage; the patient record supports semilunar fibrocartilage within the knee rather than the alternative finding of smooth covering of articulating bone surfaces.
