what is aorotgraphy?
xray of the aorta after injection of contrast
what is xray of horizontal and vertical cross sectional views or slices of the body that are computer processed to create three-dimensional, or 3D images
computed axial tomography (CT)
noninvasive xray procedure uses an external magnetic field to produce a 2 dimensional view of an internal organ or structure such as the brain or spinal cord
(MRI) magnetic resonance imaging
xray images of the body are produced after the administration of radioisotopes, which track metabolism or blood flow, not anatomy
positron emission tomography (PET)
combined technical & professional components as reported with a CPT Radiology code
global service
Patient undergoes a complete chest xray which is performed on an outpatient basis at the hospital. The patient's primary care provider completed a requisition for the chest xray after evaluation of shortness of breath. The RT takes the xray and the radiologist interprets the image and documents an xray report. A copy is mailed to the primary provider. Who reports what?
The hospital reports the xray as a global service

The primary provider reports the xray code with HCPCS lev 2 modifier -TC, The hand specialist reports the xray code with CPT modifier -26
Patient underwent ultrasound exam of the swollen tonsils, (Code 76536 is reported for the 'ultrasound, soft tissues of the head/neck real time w/ image documentation').what is reported
because just the tonsillar tissue was evaluated code 76536 is reported with modifier -52
A patient presents to the ED with blunt abdominal trauma. complete acute abdomen series with supine, erect and decubitus views & single view chest xray was performed. The pt became unstable several hours later in the ED, and the xray was repeated. Do you report the xray 2x?
yes, report 74022 twice and add -76 to the second one
what modifier isnt usually added to radiology codes?
modifier -51 (multiple procedures)
When the radiologist provides E/M services as part of the radiographic procedure, do you report both?
no, the services provided by the radiologist include a minimal history and exam, unless the E/M is significantly separate and distinct from the radiographic procedure
The pt's primary provider requests that a radiologist provide consultation services to render an opinion about the pt's candidacy for a uterine emboliztion procedure. The raiologist performs a comprehensive history and exam and reviews the pt's record. A pelvic MRI is performed to assist in medical decision making. What is reported?
radiologist report a code from the Consultations category of E/M section
Contrast studies that require injection of contrast are called?
interventional because they are considered invasive
are used to diagnose and treat conditions using percutaneous or minimally invasive techniques under imaging guidance, are considered invasive procedures
interventional radiologic procedures
When you see the term "radiological supervision and interpretation" that means the radiologic service was a part of a component...?
component coding; which allows for reporting a radiology procedure and a surgical procedure code to completely describe the service provided
In a hospital outpt setting, a radiologist performed an injection procedure and supervised and interpreted an antegrade pyelography thru a previously placed nephrostomy. What is reported?
The hospital reports codes 50394 (surgery for antegrade pyelography injection) and 74425 (radiologic supv/interp. of antegrade pyelography
When contrast material is administered _______ or _______ the administration of the contrast is not reported separately. It is included in the radiologic procedure performed
orally; rectally
The supply of contrast material, should be reported with?
HCPCS level 2 codes
When radiographic procedures are repeated during the same encounter due to substandard quality, do you report the repeat?
no just one one code
If after reviewing initial films the radiologist elects to obtain additional views to render further interpretation, do you report the extra views?
generally its included in the one code check with 3rd party payer's policy regarding multiple procedures
Descriptions of many radiology codes refer to a "minimum" number of views. When more than the minimum number specified in the code description is performed and a more specific code is not available, what do you report?
report 1 code for the highest level of service
The pt presented to the ED with the complaint of severe shortness of breath. A single view, frontal, chest x-ray was obtained. A repeat chest xray, complete (minimum of 4 views) was obtained several hours later after it was noted that the pt was experiencing labored breathing unrelieved by meds, what do you report?
report codes for the single and the complete chest xray add modifier -59 to second xray
Are preliminary scout radiographs (obtained prior to contrast administration), reported separately?
yes when there is a CPT code available to classify scout radiographs, if not then its included in the code for the primary procedure
According to CPT Assistant when radiographic supv & interp. are performed during surgical procedures__________ is included in the radiologic procedure code.
fluoroscopy
refers to the fluid filled space btwn the layers of the tissue that cover the brain/spinal cord
intrathecal
Patient underwent CT of the cervical spine with IV injection of contrast material, Report?
72126
***Paient underwent CT of the thoracic spine with intrathecal injection of contrast, Report?
72129 and 62284
Patient underwent cystography (3views) whcih involved insertion of a catheter thru the pt's urethra into the bladder and injection of contrast material, x-rays were taken from various angles at various stages of filling to visualize the bladder, do you report for the insertion of catheter & injection of contrast?
Report 74430 (cystography) and 51600 (cystography,injection). Do not report for catheter insertion. [For urologic procedures and other surgeries, the insertion of a urethral catheter is included in the radiologic procedure & not separately reported. However, a code for the injection procedure to administer dye or radionuclide material is reported]
Less invasive technique that uses cray beams to image blood vessels?
computed tomographic angiography (CTA)
What is the key distinction between CTA and CT?
CTA includes reconstruction post-processing of angiographic images and interpretation, if reconstruction post-processing is not performed, the procedure is not a CTA study
What is epidurography?
