Indications and Limitations of Coverage
General Criteria (1-6) for coverage of symptomatic varicose veins All of the following general criteria must be met for any and all varicose vein treatment to be considered for coverage. All criteria needs to be documented in the patient's medical record and available upon request.
When conservative treatments fail to provide relief from symptomatic varicosities and the above general criteria requirements (1-6) are met, the following surgical options are eligible for reimbursement when reported for symptomatic varicose veins. However, in addition to the general criteria (1-6), specific requirements for each procedure must also be met and documented in the patient’s medical record.
When reported for conditions other than symptomatic varicose veins, these surgical options are considered cosmetic, and therefore, non-covered. This includes the diagnosis of non-symptomatic varicose veins. A participating, preferred or network provider can bill the member for the non-covered service. Ligation/stripping and phlebectomy (i.e., stab, hook, transilluminated powered)(37700-37761, 37780-37785, 37765, 37766, and 37799)
Endovenous ablation (36475, 36476, 36478, 36479) and Endomechanical Ablation (37799) Endovenous ablation and endomechanical ablation is considered cosmetic, and therefore, non-covered for all of the following:
One session of endovenous ablation therapy each of the greater and small saphenous veins of one or both legs may be considered medically necessary. A total of four sessions may be authorized to treat these veins. However, the medical necessity of the treatment of these veins must be established. Endovenous ablation procedures are considered cosmetic for all other indications. Additional procedures including ligation or sclerotherapy performed in the same treatment session on the same ablated saphenous vein are included in the reimbursement of the ablation procedure. Procedures on other saphenous vein systems are eligible for reimbursement based on multiple surgery guidelines. Please refer to Medical Policy Bulletin, S-100, for information on Multiple Surgical Procedures. Endovenous radiofrequency obliteration of veins (VNUS), laser obliteration, and endomechanical ablation of incompetent veins (EVLT) include imaging guidance. Ultrasound performed within six months following the most recent ipsilateral treatment, in the absence of complications, is considered not medically necessary, including but not limited to, routine confirmation studies following endovenous/endomechanical ablation. Endovenous radiofrequency obliteration of veins (VNUS), laser obliteration, and endomechanical ablation of incompetent veins also include catheter insertion as part of the overall procedure. Echosclerotherapy (S2202) Sclerotherapy (36470, 36471)
Coverage for sclerotherapy for these indications is limited to a maximum of three (3) sclerotherapy treatment sessions per leg, without additional clinical documentation, when performed within 12 months of the initial invasive varicose vein procedure. The number of medically necessary sclerotherapy injection sessions varies with the number of anatomical areas that have to be injected, as well as the response to each injection. Usually one to three injections are necessary to obliterate any vessel, and 10 to 40 vessels, or up to a maximum of 20 injections in each leg, may be treated in any one session. Requests for additional sclerotherapy sessions are subject to medical necessity review. Sclerotherapy of the following veins is considered experimental/investigational, and therefore, non-covered. A participating, preferred, or network provider can bill the member for the non-covered service:
Sclerotherapy of small veins (less than 5mm in diameter), superficial reticular veins and/or telangiectasias (spider veins) is considered cosmetic, and therefore, non-covered. Requests for additional sclerotherapy treatment, extending beyond the maximum three (3) treatment sessions per leg, may be considered for coverage when ALL of the following additional criteria have been met. All documentation must be maintained in the patient's medical record and available upon request:
Requests for treatment sessions extending beyond one year from the initial invasive treatment session may be similarly subject to a new medical necessity review. All documentation must be maintained in the patient's medical record and available upon request. Sclerotherapy performed by the surgeon, his associate or, the assistant surgeon during the postoperative period following vein ligation and stripping procedures is part of the global surgical allowance. Sclerotherapy should be reported under codes 36470 for one vein or 36471 for multiple veins on the same leg. Codes 36470 and 36471 should be reported only once per leg. Surgical treatment of varicose veins on the contralateral extremity is eligible only if that leg is also symptomatic. Reimbursement for codes 36470 and 36471 includes the cost of the sclerosing agent; therefore, when code J3490 is reported in addition to code 36470 or 36471, no additional allowance will be made. Modifier 59 may be reported with code J3490 to identify it as a significant, separately identifiable service from the sclerotherapy. When the 59 modifier is reported, the patient's records must clearly document that an injection was provided as a separately identifiable service. Also when reporting code J3490, please include the name of the drug in the narrative section of the electronic or paper claim. Subfascial Endoscopic Perforator Surgery (SEPS)(37500)
SEPS is considered cosmetic, and therefore, non-covered for all other indications including, but not limited to, the treatment of venous insufficiency as a result of post-thrombotic syndrome. A participating, preferred, or network provider can bill the member for the non-covered service. Non-Covered Services Treatment of Spider Veins (36468 and 36469, 37799)
Procedure codes 17106-17108 should not be used to report the treatment of reticular veins and/or spider veins. See Medical Policy Bulletin S-28 for information regarding Cosmetic Surgery. Non-Invasive Laser Treatment (37799) In addition, this method of treatment for larger veins is considered experimental/investigational, and therefore, non-covered. Scientific evidence does not demonstrate the effectiveness of this treatment. A participating, preferred or network provider can bill the member for the non-covered service. Place of Service: Outpatient Treatment of varicose veins are typically outpatient procedures which are only eligible for coverage as an inpatient procedure in special circumstances, including, but not limited to, complications related to these procedures. Description The venous system of the lower extremities consists of the superficial system (e.g., long and short saphenous veins and saphenous tributaries) and the deep system (e.g., popliteal and femoral veins). These two parallel systems are interconnected via perforator veins and at the saphenofemoral and the saphenopopliteal junctions. The long and short saphenous veins are also known as the great or greater and the small or lesser saphenous veins, respectively. This policy uses the nomenclature long saphenous vein and short saphenous vein as these terms are consistent with current CPT nomenclature. One-way valves are present within all veins to direct the return of blood up the lower limb. Larger varicose veins, many protruding above the surface of the skin, typically are related to valve incompetence. As the venous pressure in the deep system is generally greater than that of the superficial system, valve incompetence leads to increased hydrostatic pressure transmitted to the unsupported superficial vein system. Backflow (venous reflux) with pooling of blood ultimately results in varicosities. In addition, clusters of varicosities may appear related to incompetent perforating veins, such as Hunter and Dodd, located in the mid- and distal thigh, respectively and/or associated with incompetence at the saphenofemoral junction. In some instances, the valvular incompetence may be isolated to a perforator vein, such as the Boyd perforating vein located in the anteromedial calf. These varicosities are often not associated with saphenous vein incompetence since the perforating veins in the lower part of the leg do not communicate directly with the saphenous vein. Although many varicose veins are asymptomatic, when present, symptoms include itching, heaviness, and pain. In addition, chronic venous insufficiency secondary to venous reflux can lead to peripheral edema, hemorrhage, thrombophlebitis, venous ulceration, and chronic skin changes. Treatment of venous reflux/venous insufficiency is aimed at reducing abnormal pressure transmission from the deep to the superficial veins. Varicose veins can usually be treated with non-surgical measures. Symptoms often decrease when the legs are elevated periodically, when prolonged standing is avoided, and when elastic compression stockings are worn. If conservative treatment measures fail, additional treatment options typically focus first on identifying and correcting the site of reflux, and second on redirecting venous flow through veins with intact valves. Thus conventional surgical treatment of varicosities is based on the following three principles:
Over the years various different minimally invasive alternatives to ligation and stripping have been investigated, including sclerotherapy and thermal ablation using radiofrequency energy (high frequency radiowaves), laser energy, or cryoablation (also called cryotherapy). |

Ambulatory phlebectomy | Ambulatory phlebectomy is a minimally invasive procedure performed as an alternative to ligation and stripping of veins that are too large for successful sclerotherapy. Prior to the procedure, the veins are located using a Doppler ultrasound. After the vein is marked, it is removed through pinhole incisions made along the length of the vein.
|
||||||||||||||||
Echosclerotherapy | During echosclerotherapy, duplex ultrasound is used to guide the injections and enhance the precision of the therapy. Echosclerotherapy is also called aimed sclerotherapy, duplex sclerotherapy, or sonographic sclerotherapy.
|
||||||||||||||||
Endovenous radiofrequency | Endovenous radiofrequency (e.g., the VNUS Closure procedure) is a minimally invasive treatment used as an alternative to saphenous vein ligation and stripping in patients with symptomatic venous insufficiency of the lower extremities (e.g., varicose veins). It involves the use of a catheter temporarily inserted into the patient's saphenous vein. This procedure utilizes radiofrequency energy at the catheter tip to heat the vein to approximately 85 degrees, which results in contraction of the vein. As the catheter is slowly withdrawn from the vein, the heat causes the vein to collapse and occlude thus terminating the reflux that causes the patient's symptoms.
|
||||||||||||||||
Laser obliteration | Laser obliteration of incompetent veins is also a minimally invasive procedure that is performed in a fashion similar to endovenous radiofrequency obliteration. A bare tipped laser fiber is introduced into the saphenous vein under ultrasonic guidance. The laser is activated and slowly removed along the course of the saphenous vein.

Sclerotherapy | The objective of sclerotherapy is to destroy the endothelium of the target vessel by injecting an irritant solution (either a detergent, osmotic solution, or a chemical irritant), ultimately resulting in the complete obliteration of the vessel. The success of the treatment depends on accurate injection of the vessel, an adequate injectant volume and concentration of sclerosant, and post-procedure compression. Compression theoretically results in direct apposition of the treated vein walls to provide more effective fibrosis and may decrease the extent of the thrombosis formation. Sclerotherapy is an accepted and effective treatment of telangiectatic vessels. Historically, larger veins and very tortuous veins were not considered to be good candidates for sclerotherapy. Technical improvements in sclerotherapy, including the routine use of Duplex ultrasound to target refluxing vessels, luminal compression of the vein with anesthetics, and a foam sclerosant in place of liquid sclerosant, have improved its effectiveness in these veins. Other concerns have arisen with these expanded uses of sclerotherapy. For example, use of sclerotherapy in the treatment of varicose tributaries without prior ligation, with or without vein stripping creates issues regarding its effectiveness in the absence of the control of the point of reflux and isolation of the refluxing saphenous vein. Sclerotherapy of the long saphenous vein raises issues regarding appropriate volume and concentration of the sclerosant and the ability to provide adequate post-procedure compression. Moreover, the use of sclerotherapy, as opposed to the physical removal of the vein with stripping, raises the issue of recurrence due to recanalization.

Subfascial endoscopic perforator surgery (SEPS) | Perforator veins cross through the fascia and connect the deep and superficial venous systems. Incompetent perforating veins were originally addressed with an open surgical procedure, called the Linton procedure, which involved a long medial calf incision to expose all posterior, medial, and paramedial perforators. While this procedure was associated with healing of ulcers, it was largely abandoned due to a high incidence of wound complications. The Linton procedure was subsequently modified by using a series of perpendicular skin flaps instead of a longitudinal skin flap to provide access to incompetent perforator veins in the lower part of the leg. The modified Linton procedure may be occasionally utilized for the closure of incompetent perforator veins that cannot be reached by less invasive procedures. Subfascial endoscopic perforator surgery (SEPS) is a less-invasive surgical procedure for treatment of incompetent perforators and has been reported since the mid-1980s. Guided by Duplex ultrasound scanning, small incisions are made in the skin and the perforating veins are clipped or divided by endoscopic scissors. The operation can be performed as an outpatient procedure. Endovenous ablation of incompetent perforator veins with sclerotherapy and radiofrequency has also been reported.

Transilluminated powered phlebectomy | Transilluminated powered phlebectomy (e.g., TriVex System) is a minimally invasive procedure in which an endoscopic illuminator is inserted into the vein to allow visualization of the varicose vein clusters. The veins are then ablated using a vein resector. During destruction of the veins, the debris is removed from the wound using suction.

Endomechanical ablation
| Endomechanical ablation (e.g., ClariveinTM [Vascular Insights, Madision, CT]) is a minimally invasive treatment for varicose veins, combining mechanical and chemical modalities. The procedure involves the use of a special percutaneous infusion catheter which contains a rotating wire, providing endovenous mechanical destruction. Simultaneously, an FDA-approved sclerosing agent (e.g., sodium tetradecyl sulfate) is administered in order to enhance occlusion of the vein.

CEAP Classification | Venous disease of the legs can be classified according to the severity, cause, site and specific abnormality using the CEAP classification. Use of such a classification improves the accuracy of the diagnosis and improves communication between specialists. The elements of the CEAP classification are:
