    CPT 37799: Unlisted Vascular Surgery Procedure

    Commercial payers pay $1982 on average nationally for this procedure.

    CPT code 37799 is used to report an unlisted vascular surgery procedure when no specific CPT code exists for the vascular intervention performed; the service typically represents an operative vascular procedure such as vein ligation, repair, thrombectomy, or other vascular reconstruction and is performed in an operating room or vascular surgery suite by a vascular surgeon or surgical team.

    For related coverage guidance, see recent payer policy updates: Surgical Procedures, Outpatient Surgical Procedures - Site of Service, Site of Service Ambulatory Service Center (ASC) Select — Surgical or Diagnostic Procedures in Adults.

    National Reimbursement Benchmarks

    Commercial reimbursement for CPT 37799 centers near BUCA’s average commercial rate of $1,982.20, with notable variation among large national payers. Blue Cross Blue Shield shows the broadest dispersion (P75 $1,427.80 minus P25 $109.40 = $1,318.40), reflecting a wide mix of low and high contract levels. Aetna also has substantial spread (P75 $2,022.40 minus P25 $446.90 = $1,575.50) driven by a high maximum of $7,233.20, while Cigna’s values are tightly clustered around a single principal level (P75 $1,358.00 minus P25 $1,358.00 = $0.00). UnitedHealth Group’s dispersion is moderate (P75 $2,547.90 minus P25 $600.00 = $1,947.90).

    These patterns indicate that price certainty is strongest with Cigna, where median and quartiles coincide at $1,358.00, and weakest with Aetna and UnitedHealth Group by range magnitude. Blue Cross Blue Shield shows extreme outliers (minimum $0 and maximum $60,000) that widen its overall profile despite a median of $620.00. BUCA’s mean of $1,982.20 provides an industry-average anchor point against which these payer-specific dispersions can be compared.

    Clinical & Coding Specifications

    Clinical Context

    A 62-year-old patient with chronic venous insufficiency presents with progressive lower-extremity symptoms including pain, edema, and visible varicosities refractory to conservative measures. Duplex ultrasound identifies atypical venous anatomy and an incompetent accessory vein not amenable to standard endovenous ablation or listed ligation codes. The vascular surgeon schedules an operative procedure to address the abnormal vein with an approach that does not have a specific CPT code, and reports 37799 for the unlisted vascular surgery procedure. The typical workflow includes preoperative duplex mapping, intraoperative venous exposure and treatment (ligation, excision, or bypass as clinically indicated), and postoperative duplex to confirm technical success. The typical site of service is an ambulatory surgical center or hospital operating room under vascular surgery (Taxonomy 208800000X). Common payors for prior authorization and claims submission include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
