|---|---|
| CAT Scan | Computerized Axial Tomography. |
| MRI | Magnetic Resonance Imaging |
| Fluoroscopy | Xray exam in real time. Body organ is displayed on a monitor for doctor to view as a surgical procedure is performed. |
| Professional Component | Either supervision or interpretation of an Xray. (modifier -26) |
| Technical Component | Portion of Xray exam done by technicians. Includes materials used during the procedure. Modifier -TC |
| Stark Law | Part of the new insurance federal insurance plan. Requires doctors to refer patients to all imaging sources; not just the ones the doctor has a financial interest in. |
| Contrast | A medium that is injected into a patient to enhance scanned or Xray images. |
| Modifier -51 | Multiple procedures |
| bilateral | both sides |
| supine | lying on the back |
| prone | lying face down |
| AP | front (anterior) to back (posterior) path of beam |
| PA | back to front path of beam |
| proximal | close to |
| distal | far from |
| tangental | Xray beam skims the surface or edge of of the body part. |
| Plus code | CPT code that is added to another related code. |
| oblique | diagonal line |
| Multiple procedure modifier | -51 |
| Bilateral procedure modifier | -50 |
| When do you use a modifier for an Xray that requires contrast medium | This is found in the CPT notes. |
| S&I | Supervision and Interpretation, or Scanning & Imaging |
| dosimetry | Measurement of the effects of radiation on tissues. |
| -26 | Modifier for Professional component |
| -TC | Modifier for Technical component |
| When you see "with contrast" as part of a code description you cannot charge for... | contrast medium or the injection. |
| Interventional radiology is used for location and treatment. Here the doctor is: | Both a radiologist and a surgeon |
| When an xray needs contrast material and the code does not have "with contrast" you can: | code for the injection code for the contrast material injected |
| Angiograpny | Xray of blood vessel |
| A doctor has a patient visit an xray clinic for a chest xray. The clinic does the procedure and sends the doctor the xray. What does the clinic charge for: | The clinic charges for the procedure and materials required.They also need to use modifier -TC |
| supine | lying on the back |
| Prone or Ventral position | lying on stomach |
| ventral decubitus | lying on stomach with Xray beam aimed at the side. |
| RAO | right anterior oblique. Body is diagonal to beam. The beam projects back to front |
| LPO | left posterior oblique. Body is diagonal to beam. The beam projects from front to back. |
| Dorsal | back |
| What is the code for: Code for a complete chest Xray four views. Technical component only. | 71030-TC |
| What is the code for a complete chest Xray, four views - Professional component only | 71030-26 |
| Component or combination coding | A code from the Radiiology sections and a code from another section of the CPT book is required to fully describe the procedure. |
| position | How the pt. is placed (positioned) for the Xray |
| projection | The path of the Xray beam. Indicates the direction through the patient. |
| lateral | to the side |
| right lateral | pt. right side is closest to the film. |
| left lateral | pt. left side is closest to the film. |
| Ventral | Refers to the front. May be stated as "prone" Means that pt. is lying on stomach |
| Decubitus positions | Recumbent (lying down) Xray beam goes into the patient's side (horizontal). |
| recumbent | lying down. |
| global | Both professional and technical components. No modifier is used if you code for global procedure. |
| -52 | Modifier 52 is used to indicate less of the procedure was performed than is described by the code. |
| ultrasound | Use of high frequency sound waves to diagnose and treat disease. |
| A doctor injects a contrast material into the patient. A technician takes the Xrays The doctor performs S&I for an Xray. How many codes are there? | 1. code for the injection 2. One code for the global Xray (both technical and professioinal) |
| A CXR complete 4 views is ordered. There could only be 3 views completed. What is the code? | CXR 71030 for the Xray Modifier -52 to indicated that less than 4 views were taken. |
| interventional radiology | sub-specialty of radiology which utilizes minimally-invasive image-guided procedures to diagnose and treat diseases in nearly every organ system. |
