Numerous interventional radiology changes in CPT

Radiology Administrator's Compliance and Reimbursement Insider, December 1, 2005

By Jackie Miller, RHIA, CPC

There is one significant change for diagnostic radiology and numerous changes for interventional radiology in the 2006 edition of CPT®. I will discuss these briefly in this article and explore them in more depth in future issues.

Reconstruction

The new version of the CPT deletes code 76375 (coronal, sagittal, multiplanar, oblique, three-dimensional [3-D]/ holographic reconstruction of computed tomography, magnetic resonance imaging[MRI], or other tomographic modality) and adds two new codes for 3-D rendering of tomographic studies:

Two-dimensional reconstruction (e.g., reformatting an axial scan into the coronal plane) is now considered part of the tomography procedure and is not separately reportable. However, report 3-D reconstruction in addition to the tomographic exam using codes 76376 and 76377.

Do not report the new 3-D rendering codes. They, like the old reconstruction code, cannot be reported with magnetic resonance angiography or CTA because image postprocessing is an integral part of the angiography procedure.

Mechanical thrombectomy

New codes have been added to CPT for mechanical thrombectomy in peripheral arteries and veins. Previously, there were codes only for mechanical thrombectomy of coronary arteries and dialysis fistulas.

The new mechanical thrombectomy codes are classified according to whether treatment occurs in an artery (new codes 37184-37186) or a vein (new codes 37187-37188). The arterial codes are classified according to whether mechanical thrombectomy was the primary means of treatment (37184-37185) or was performed in conjunction with another therapy, such as angioplasty (37186).

All of the new codes include fluoroscopic guidance, and there are no separate supervision and interpretation codes. However, code catheter placement separately. Similarly, code diagnostic angiography separately if it meets the criteria for a separate procedure (e.g., the patient has had no prior catheter angiogram).

Catheter check

There is also a new code for a contrast exam of an indwelling vascular catheter. Previously, there was no code for this procedure, so it was typically reported with the unlisted injection code (36299) in addition to fluoroscopy (76000) or a venogram code, depending upon the documentation.

Note that the new code includes fluoroscopy, so do not report an imaging code with 36598 unless a separate diagnostic venogram is performed.

Kyphoplasty

There are also new codes for kyphoplasty. Previously, this procedure was reported by physicians with code 22899 and by hospitals with codes C9718-C9719 (see the July 2005 RACRI ).

Additionally, the guidance codes for vertebroplasty (76012-76013) have been revised, so they can be used with either vertebroplasty or kyphoplasty.

Note that the new kyphoplasty codes include bone biopsy by definition.

Other changes

In addition to the changes discussed above, there are new and revised codes for the following procedures:

  • Endovascular repair of thoracic aortic aneurysm

  • Removal/replacement of ureteral stent

  • Removal of nephrostomy tube

  • Percutaneous radiofrequency ablation of renal tumors

  • Intracranial stent placement

  • Balloon dilation of intracranial vasospasm

    Finally, some little-used nuclear medicine codes have been deleted (e.g., 78162, radioiron oral absorption).

    Under the Health Insurance Portability and Accountability Act of 1996 transactions and code set standards, payers should accept the new and revised 2006 codes for services provided on January 1 and after.

    Between now and January 1, providers should update their charge documents and train their coding and billing personnel on the new codes. Providers should also watch the CMS Web site (or the Federal Register ) for the final 2006 Medicare regulations for hospital and physician payment, which will explain Medicare payment policy changes for 2006.

    Removing primary tumor may spur growth of metastases

    A new study shows that surgery to remove a primary breast cancer tumor may result in the formation of a new blood supply in metastases that were dormant, causing a cancer relapse, according to Women's Health Law Weekly .

    The study, published by the International Journal of Surgery, reviewed data from three clinical trials that involved women who had surgery for breast cancer, but no further treatment.

    "Cancer outgrowth after surgery has been observed for over 100 years, and the mechanisms have not been fully identified," researcher Michael Retsky, PhD, told Women's Health Law Weekly .

    "Our analysis suggests that biology may be the underlying cause, rather than something going wrong during surgery. It also suggest that [although] most young women benefit from early detection of breast cancer, a small percentage will relapse and die early of metastatic disease. The paper suggests remedial steps that might prevent the sudden growth from occurring."
