CPT codes 36473, 36474, 36475, and 36476 are used to report endovenous ablation procedures for the treatment of varicose veins. Here are some coding tips for using these codes:
- Confirm medical necessity: Before assigning a CPT code for endovenous ablation procedures, it is important to confirm that the procedure was medically necessary. This may involve reviewing the patient’s medical history, diagnostic imaging, and any other relevant clinical information.
- Assign the correct code: The appropriate code should be assigned based on the type of endovenous ablation procedure performed. CPT code 36473 is used to report endovenous laser ablation (EVLA), 36474 is used to report endovenous radiofrequency ablation (EVRF), 36475 is used to report endovenous mechanochemical ablation (MOCA), and 36476 is used to report endovenous chemical ablation (CA).
- Use appropriate modifiers: Modifier -LT and -RT may be used to indicate the side on which the procedure was performed if the procedure is bilateral.
- Ensure complete documentation: Accurate and complete documentation is crucial when coding for endovenous ablation procedures. The documentation should include information about the type of procedure performed, the specific veins treated, the location and size of any access incisions, and any intraoperative findings or complications.
- Assign additional codes: If additional procedures or services are performed in conjunction with the endovenous ablation procedure, additional CPT codes may be necessary to report these services. For example, a separate code may be used to report imaging guidance for the procedure or the use of ultrasound to guide the catheter.
- Follow local guidelines: Be sure to follow any local coding guidelines or payer policies that may impact coding for endovenous ablation procedures. Some payers may have specific requirements for documentation or coding of certain procedures.
