CPT 38520: Deep Cervical (Scalene) Lymph Node Excision

CPT code 38520 represents open surgical excision of deep cervical (neck) lymph nodes and the scalene fat pad, often with submission of tissue for pathological analysis. This procedure is performed for diagnostic evaluation or treatment of tumors in the neck or chest and is an important code for surgical oncology, otolaryngology, and thoracic surgery services nationwide.

Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The code is relevant to hospital and ambulatory surgical center billing, and it intersects with pathology services when specimens are sent for analysis.

Readers will learn the clinical context and typical care setting for CPT code 38520, common billing and claim considerations tied to surgical lymphadenectomy, and how this code fits into service lines for surgical oncology and head-and-neck procedures. The publication also summarizes payer coverage patterns, common modifiers used with surgical procedures, and where to look for policy updates affecting use and reimbursement. Data not available in the input will be identified explicitly in detailed sections.

Clinical & Coding Specifications

Clinical Context

A 58-year-old patient presents with a palpable supraclavicular mass and imaging (CT chest/neck and PET-CT) demonstrating suspicious lymphadenopathy in the lower deep cervical and supraclavicular region with concern for metastatic carcinoma of unknown primary. After multidisciplinary review, the surgical team plans an open supraclavicular lymph node dissection with removal of the scalene fat pad to obtain tissue for definitive histopathology and staging. The patient is admitted or scheduled as an outpatient surgical case based on comorbidity and extent of dissection. Preoperative workflow includes history and physical, focused head and neck exam, informed consent documenting risks (bleeding, nerve injury including spinal accessory nerve, pneumothorax), perioperative antibiotics, anesthesia evaluation, and marking of laterality. Intraoperative steps include an open incision in the neck, dissection of deep cervical lymph nodes and scalene fat pad, hemostasis, and specimen labeling and submission to pathology. Postoperative workflow includes monitoring for airway compromise, nerve function assessment, pain control, pathology follow-up for tumor type and staging, and coordination of oncology for adjuvant therapy if malignant disease is confirmed.

Coding Specifications

Modifier	Description	When to Use
`00`	No modifier — standard unmodified claim	Use when no modifier is applicable and the service is bilateral/unilateral as reported by the base code.
`11`	Office/Outpatient/Emergency — Default billing modifier indicating the service is the usual and customary service	Use when the procedure is performed as scheduled (routine) without unusual circumstances.
`22`	Increased procedural services	Use when work, time, or complexity substantially exceeds the typical service (document rationale).
`23`	Unusual anesthesia — medical condition	Use when the procedure is performed under local or no anesthesia because of a documented medical condition precluding general anesthesia.
`26`	Professional component	Use if reporting only the surgeon’s professional component separate from facility technical component (rare for operative CPTs).
`50`	Bilateral procedure	Use when material or dissection is performed on both sides and payer requires bilateral modifier reporting.
`51`	Multiple procedures	Use when additional distinct procedures are performed at the same session in addition to the lymph node dissection (list additional codes).
`52`	Reduced services	Use when the procedure is partially reduced or not completed as originally planned (document reason).
`62`	Two surgeons — co-surgeons	Use when two surgeons from different specialties perform distinct portions of the operation concurrently and both bill.
`63`	Procedure performed on infants less than 4 kg	Use for qualifying neonatal cases when weight criteria are met.
`78`	Return to the OR for a related procedure during global period	Use when the patient returns to the operating room for treatment of a complication related to the original procedure.
`80`	Assistant surgeon	Use when an assistant surgeon is present and an assistant is payable by the payer.
`81`	Minimum assistant surgeon	Use when a minimal assistant contribution is documented and payable.
`82`	Assistant surgeon (when a qualified resident is not available)	Use when an assistant is necessary and resident coverage is not available.

Taxonomy Code	Specialty	Notes
2080S0001X	Otolaryngology (ENT)	Common specialty performing neck lymph node dissections for head and neck malignancy.
