YOU BE THE EXPERT:

Are Dilations and Ablations Separately Reportable?

Published on Mon Jun 28, 2004

Question: The ob-gyn performed endometrial ablation on a patient after performing cervical dilation on her four hours earlier in the same day. How should we report this visit, and are we allowed to report the dilation separately?

Answer: The ablation code depends on the method the physician used, but the dilation can be reported regardless of that method.

If the ob-gyn used a hysteroscope to accomplish the ablation, you should:

  • report 58563 (Hysteroscopy, surgical; with endometrial ablation [e.g., endometrial resection, electrosurgical ablation, thermoablation]) for the ablation.
  • attach modifier -59 (Distinct procedural service) to 59200 (Insertion of cervical dilator [e.g., laminaria, prostaglandin] [separate procedure]). The modifier tells the carrier that the dilation is a distinctly different procedure than the ablation.

    If the ob-gyn used the thermal balloon procedure to accomplish the ablation, you should:

  • report 58353 (Endometrial ablation, thermal, without hysteroscopic guidance) for the ablation.
  • attach modifier -59 to 59200.

    Remember: If the ob-gyn performed the dilation at the same time as the ablation, you cannot report the dilation separately. But some physicians -- such as the one in this example -- may dilate the patient earlier in the day, then perform the ablation later.
