Summary & Overview

CPT 36470: Sclerotherapy Injection for Varicose Vein

CPT code 36470 denotes sclerotherapy involving injection of a sclerosing solution into a single vein, most often used to treat varicose veins and some vascular malformations (excluding telangiectasia). Nationally, this procedure is a common, minimally invasive option in vascular and phlebology care pathways and has implications for ambulatory care utilization and outpatient procedural billing.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context, typical sites of service, and the common payer landscape affecting coverage and claims processing. The publication summarizes national benchmarks where available, highlights relevant policy and coding considerations related to outpatient procedural billing, and outlines the clinical scenarios in which 36470 is applied.

This analysis is intended for billing professionals, practice managers, and clinicians seeking a concise reference on the clinical purpose and payer context of CPT code 36470. Data not provided in the input are noted as unavailable; the focus remains on clinical description, service setting, and the payers commonly involved in coverage and reimbursement decisions.

Billing Code Overview

CPT code 36470 describes injection of a sclerosing solution into a single vein, most commonly performed to treat a varicose vein. The procedure targets abnormal venous segments and may be used for other vascular malformations except for spider veins (telangiectasia).

Service Type: Sclerotherapy — percutaneous vein injection

Typical Site of Service: Outpatient clinic, physician office, or ambulatory surgical center

Data not available in the input.

Clinical & Coding Specifications

Clinical Context

A typical patient is a 52-year-old ambulatory adult presenting to an outpatient vascular clinic with a symptomatic varicose vein of the lower extremity causing aching, swelling, and cosmetic concern. The patient has had duplex ultrasound confirming reflux in a single incompetent superficial vein segment appropriate for sclerotherapy. The procedure is scheduled in an office-based procedure room or ambulatory surgery center. The provider obtains informed consent, documents indications and prior conservative care (compression, leg elevation), and confirms no contraindications (active infection, allergy to sclerosant, pregnancy). Under ultrasound guidance or direct visualization, the provider injects a sclerosing solution into the targeted vein (CPT 36470) using sterile technique. Post-procedure care includes compression dressing, ambulation instructions, and follow-up arranged for assessment of efficacy and complications such as phlebitis or thrombosis. Billing reflects a single vein treated under CPT 36470 with relevant modifier use documented when applicable.

`25`	Significant, separately identifiable E/M service by the same physician on the same day of the procedure	When an office visit with documented medical decision-making is performed and is above and beyond the pre-procedural work for `CPT` `36470`.
`26`	Professional component	When billing is split and the physician bills only the professional component of a service related to imaging or diagnostic interpretation accompanying the procedure.
`50`	Bilateral procedure	When the same sclerotherapy procedure is performed on both limbs and payer requires bilateral modifier reporting.
`52`	Reduced services	When the procedure is started but substantially reduced or not completed (partial treatment of planned vein segment).
`53`	Discontinued procedure	When the procedure is aborted for reasons unrelated to patient tolerance (e.g., sudden medical condition preventing completion).
`59`	Distinct procedural service	When another separately identifiable procedure on the same day is distinct from the sclerotherapy (e.g., unrelated injection at a different anatomic site).
`76`	Repeat procedure by same physician	When the same procedure is repeated later the same day by the same physician (useful if multiple treatment attempts required).
`77`	Repeat procedure by another physician	When the same procedure is repeated later the same day by a different physician.
`78`	Unplanned return to the operating/procedure room for a related procedure during the postoperative period	When the patient requires an unplanned return to treat a complication related to the original sclerotherapy.
`79`	Unrelated procedure or service by the same physician during the postoperative period	When an unrelated procedure is performed during the global period.
`LT`	Left side	When documenting laterality for left-sided sclerotherapy procedures.
`RT`	Right side	When documenting laterality for right-sided sclerotherapy procedures.
`22`	Increased procedural services	When the service required substantially greater resources or time than typical and documentation supports unusual effort.
`52`	Reduced services	When the service performed is partially reduced or not completed (included for relevance in partial vein treatments).

Taxonomy Code	Specialty	Notes
`207K00000X`	Vascular Surgery	Common specialty performing sclerotherapy and venous interventions.
`2087S0122X`	Interventional Cardiology	Some interventional cardiologists with venous expertise perform venous sclerotherapy.
`208D00000X`	General Surgery	General surgeons with vascular interest may perform this procedure in clinic or ASC.
`207L00000X`	Radiology (Vascular & Interventional)	Interventional radiologists perform image-guided sclerotherapy for complex venous malformations.
`207P00000X`	Podiatry	Podiatrists may perform sclerotherapy for distal lower-extremity superficial veins when within scope of practice.

`I83.90`	Varicose veins of lower extremity with unspecified ulcer and unspecified lower extremity	Represents varicose vein disease commonly treated with sclerotherapy when specific laterality/detail is not documented.
`I83.20`	Varicose veins of lower extremity with pain	Symptomatic varicose veins with pain are an indication for sclerotherapy to reduce symptoms.
`I83.10`	Varicose veins of lower extremity with inflammation	Inflammation or phlebitis of superficial varicosities can be an indication for targeted sclerotherapy after appropriate evaluation.
`I83.00`	Varicose veins of lower extremity without complications	Uncomplicated varicose veins often treated for symptomatic relief or cosmetic reasons using sclerotherapy.
`I87.2`	Venous insufficiency (chronic) (peripheral)	Chronic venous insufficiency with superficial reflux may be managed with sclerotherapy as part of venous care.
