equipment providers, auditing of radiology services is on the immediate horizon. In fact, the OIG has placed radiology audits on their 2010 work
list. Forward thinking providers and healthcare systems are preparing now, to formulate compliance plans for diagnostic radiology services.
One area of radiology review will be documentation and proper coding of imaging procedures. CMS and OIG audits will likely include evaluation
of the referring physician’s order, appropriate CPT coding of the procedure, documentation of medical necessity and a separate written report
for each study billed.
The following are compliance issues that providers should consider,
in preparation for RAC auditing of radiology services:
1. Physician Order: Is there appropriate documentation that a treating physician or practitioner requested the specific diagnostic test
performed? This is an absolute requirement for reimbursement. Records must be maintained by the billing entity, in order to avoid potential
conflict.
2. Coding: Based upon review of images and documentation, is the coding correct and proper CPT coding utilized? For example: a complete
abdominal ultrasound is provided, but only the liver and gallbladder are imaged. Therefore, only a limited study should be billed. a radiological
examination consisting of 2 views is provided, but a “complete” radiological examination consisting of a minimum of 5 is was billed.
3. Medical Necessity: Studies must not only be ordered and coded correctly, but they must be medically necessary - used in the care and
treatment of the patient. Studies or procedures that are not indicated may be viewed as not reimbursable, and/or subject to recoupment of paid
claims.
For example:
- A CT scan is provided without contrast followed by with contrast. However, based on the patient’s condition, only a CT scan with contrast
was indicated. Not only does this represent over-coding (wrong CPT code), but the patient has received twice as much radiation as
medically necessary. - Billing for 3-D reconstructions on CT Scans, performed without documentation of medical necessity or separate physician order. In
addition, reconstructions must be performed on a separate workstation, and noted in the final written report. - Screening procedures: Ultrasound of the abdominal aorta ordered to screen for aneurysm. However, the patient does not meet
appropriate Medicare (or national standards) screening criteria.
4. Imaging Report: Auditors will undoubtedly be reviewing procedures to see that a formal written report has been issued, for cases where there
is billing for the professional interpretation (professional component). Such reporting is mandated by;
- AMA guidelines
- CMS / Medicare regulations
- American College of Radiology
- American Association of Orthopedic Surgeons
- Many other professional organizations
The RACs are coming and it’s time to get into compliance. Medical imaging is one of the areas of great interest, and healthcare
providers are well advised to get their policies and procedures in order, and to review their compliance programs in radiology.
