Coding Test Questions with All
Correct Answers.
Right hand, Three views. Hand pain, R/O Fracture from slip and fall. The specific area of clinical
concern was not indicated. No fracture, misalignment, or foreign body is evident. - Answer
73130-RT
(Assign 73130 for hand X-ray from diagnostic X-ray, Upper extremity, hand section. Append
modifier -RT to indicate right hand.)
Therapeutic radiation treatment planning, single treatment area - Answer 77261
(Assigned 77261 for single/simple therapeutic radiation treatment planning)
CT head/brain w/o contrast. Spiral CT acquisition of brain was performed. Generalized changes
of cerebral atrophy are present with prominence of the cerebral sulci and basilar cisterns.
Generalized changes of cerebral atrophy and white matter changes of aging. - Answer 70450
(CT of head/brain was performed without contrast; therefore, 70450 should be assigned from
the Diagnostic Radiology, head/brain section.)
Abdomen and pelvic CT. Multislice acquisition through the abdomen and pelvis were obtained
with and without contrast. Inflammatory changes consistent with diverticulitis were noted near
the rectosigmoid junction. The adrenal glands, kidneys, pancreas, and spleen are normal. No
free fluid or free air. - Answer 74178
(Abdomen and pelvic CT with and without contrast is assigned 74178.)
Waters view of sinus. Findings are consistent with right maxillary sinusitis. - Answer 70210
(Waters view of sinus is assigned 70210 for X-ray sinus.)
Retrograde pyelogram imaging - Answer 74420
(Assign 74420 for pyelogram imaging from Diagnostic Radiology, urinary tract section.)
Patient receives two views of chest X-ray and returns later in the day for repeat of one view
chest X-ray due to increased shortness of breath. - Answer 71046, 71045
(Two views (PA & Lat) of chest performed for which 70146 should be assigned, followed by one
view chest X-ray later in day, assign 70145. Modifier -76 is NOT assigned unless exact same
procedure (same CPT) is performed.)
, CT of head performed with and without IV contrast. Demonstrates no evidence of intracranial
hemorrhage, mass effect, or midline shift. There are no enhancing cerebral masses. - Answer
70470
(CT head performed with and without contrast, therefore, assign 70470 from Diagnostic
Radiology, head/brain section.) WRONG
MRI lumbar spine with oral contrast. T1 and T2 weighted sagittal images through the lumbar
spine are obtained. Images demonstrate degeneration and dehydration of L2-3, L3-4, L4-5, and
L5-S1 discs. There is disc space narrowing throughout the lumbar spine. There is mild annular
bulging of the L5-S1 disc with a small central disc protrusion. There is facet joint hypertrophy at
this level. There is mild neural foramen stenosis bilaterally. - Answer 72148
(Oral contrast, per radiology guidelines in CPT, does not qualify as contrast. Would assign 72148
for MRI lumbar spine without contrast.) WRONG
MRI lumbar spine with oral contrast - Answer 72148
(Oral contrast, per radiology guidelines in CPT, does not qualify as contrast. Would assign 72148
for MRI lumbar spine without contrast.) WRONG
Endoscopic catheterization of pancreatic ductal system, interpretation and supervision - Answer
74329
(Code 74329 is assigned for endoscopic catheterization of pancreatic ductal system. No modifier
is needed to indicate interpretation and supervision only as the code already contains that
information.)
Right mammogram for suspicious breast lesion - Answer 77065-RT
(Assigned diagnostic mammogram code with modifier -RT, 77065-RT.)
Chest X-ray, PA only - Answer 71045
(Chest PA (posterior/anterior) is considered one view only, therefore, 71045 is assigned.)
Ultrasound of abdomen, order states "GB Ultrasound" - Answer 76705
(Gallbladder ultrasound is considered "limited" ultrasound as abdominal ultrasound code 76705
is assigned and all areas of abdomen are not documented or imaged.)
A radiation oncologist develops a clinical treatment plan to deliver radiation to the patient's
single-bone metastasis using parallel ports with no blocking. Which code is correct? - Answer
77261
(Clinical treatment plan, simple)
A "Dec" view performed in the radiology section refers to - Answer decubitus view.
