Summary & Overview
CPT 35800: Neck Exploration for Bleeding, Clot, or Infection
CPT code 35800 designates surgical exploration of the neck to identify and correct postoperative bleeding, clot formation, or infection. It captures a targeted procedure performed when complications arise after prior cervical surgery and is relevant for hospitals and surgical practices managing postoperative emergencies. Nationally, accurate use of this code affects clinical documentation, coding integrity, and payer adjudication for acute reintervention of the neck.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for CPT code 35800, typical sites of service, and common billing modifiers associated with complex surgical services. The publication outlines benchmarks for utilization and billing practice considerations, highlights policy factors that influence coverage and payment, and situates CPT 35800 within related surgical procedure coding to support accurate claim submission.
This summary is intended for coding specialists, surgical providers, and revenue cycle professionals seeking clear guidance on the clinical and billing role of CPT code 35800 in managing postoperative cervical complications.
Billing Code Overview
CPT code 35800 describes reopening a patient’s neck incision to locate and control postoperative bleeding, evacuate hematoma, or address infection after a prior operation. This procedure involves surgical exploration of the cervical wound, identification of the source of the complication, and definitive control or debridement as indicated.
-
Service type: Surgical wound exploration and control of postoperative complication
-
Typical site of service: Operating room or procedural suite, commonly performed under general or regional anesthesia in an inpatient or outpatient surgical setting
Clinical & Coding Specifications
Clinical Context
A 58-year-old male underwent a thyroidectomy three days earlier and returns to the hospital with expanding neck hematoma, respiratory distress, and hemoglobin drop. The patient is taken emergently to the operating room for wound exploration. The surgeon reopens the prior cervical incision, evacuates hematoma and clot, identifies an arterial branch in the surgical bed as the bleeding source, secures hemostasis with suture ligation and electrocautery, irrigates the wound, assesses for infection, and closes the incision. The intraoperative team documents prior operative details, time since index operation, findings (active bleeding, clot, or purulence), steps used to control bleeding or address infection, blood loss, and wound closure method. Typical workflow includes preoperative airway assessment, anesthesia clearance (often general endotracheal), urgent operative consent (if feasible), intraoperative hemostasis and irrigation, possible drain placement, and postoperative monitoring in PACU or ICU depending on airway/bleeding risk.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the re-exploration requires substantially greater work than typical (extensive dissection, prolonged time) and documentation supports increased work. |
