38510

Biopsy or excision of deep cervical lymph node(s), open

CPT code 38510 describes a surgical procedure involving the open biopsy or excision of one or more deep cervical lymph nodes. Unlike superficial nodes located in the subcutaneous fat, deep cervical nodes are situated beneath the deep cervical fascia, frequently adjacent to the internal jugular vein, the carotid artery, or deep to the sternocleidomastoid muscle. This procedure is primarily diagnostic, performed when a physician needs to evaluate lymphadenopathy that cannot be sufficiently characterized by less invasive means such as fine-needle aspiration (FNA) or core needle biopsy. It is particularly crucial when an intact node is required to preserve architectural patterns for the diagnosis of lymphoma or when deep-seated metastatic disease is suspected. The surgeon begins by making a skin incision over the target area. The dissection proceeds through the subcutaneous tissues and the platysma muscle. The deep fascia is then incised, and the surgeon carefully navigates around critical neurovascular structures, including the spinal accessory nerve and the jugular vein, to reach the deep nodal chain. Once the target node is isolated, it is excised, often with a small amount of surrounding adipose tissue for orientation. Hemostasis is critical given the vascularity of the neck. After the specimen is removed for histopathological examination, the wound is closed in layers, typically including the platysma and the skin. This procedure is usually performed under general anesthesia or deep sedation in a hospital or ambulatory surgery center due to the technical complexity of the neck's anatomy.

Clinical Indications

  • Persistent, unexplained deep cervical lymphadenopathy
  • Evaluation of suspected lymphoma (Hodgkin or Non-Hodgkin)
  • Staging or diagnosis of metastatic squamous cell carcinoma of the head and neck
  • Inconclusive results from prior fine-needle aspiration (FNA) or core biopsy
  • Evaluation of suspected infectious diseases like tuberculosis or cat-scratch disease
  • Diagnosis of inflammatory or granulomatous conditions such as sarcoidosis
  • Monitoring response to therapy in known malignancy cases

Procedure Steps

  1. Patient is placed in a supine position with the neck extended and rotated away from the operative site.
  2. The neck is prepped and draped in a sterile fashion.
  3. A transverse or longitudinal incision is made over the location of the deep lymph node.
  4. Dissection is performed through the subcutaneous fat and the platysma muscle.
  5. The sternocleidomastoid muscle is identified and typically retracted to expose the deep cervical fascia.
  6. The deep cervical fascia is carefully incised to access the carotid sheath or the deep nodal chain.
  7. The target lymph node is identified through palpation or visual inspection.
  8. Blunt and sharp dissection is used to free the node from surrounding connective tissues and neurovascular structures.
  9. The lymph node is completely excised and oriented for the pathologist.
  10. The surgical bed is inspected for bleeding, and hemostasis is achieved using cautery or ligatures.
  11. The deep fascia and platysma layers are closed with absorbable sutures.
  12. The skin is closed using subcuticular sutures, staples, or adhesive strips.
  13. A sterile dressing is applied to the wound site.

Coding Guidelines

  • Use 38510 for open excision of deep cervical nodes; use 38500 for superficial nodes.
  • If the procedure includes excision of the scalene fat pad, report 38520 instead of 38510.
  • Do not report 38510 in conjunction with a radical or modified radical neck dissection (38720-38724) if the node is within the same operative field.
  • 38510 is a unilateral code; if performed on both sides of the neck, append modifier 50.
  • For needle biopsy of a lymph node, use 38505 instead of 38510.
  • Image guidance (e.g., ultrasound, CT) used during the open procedure may be reported separately if documentation supports it, but is rarely indicated for open deep biopsies.
  • The 'deep' designation refers to the node's location relative to the deep cervical fascia.
