Summary & Overview
HCPCS C7503: Open Biopsy/Excision of Deep Cervical Node with Sentinel Mapping
HCPCS Level II code C7503 represents an open biopsy or excision of deep cervical lymph node(s) performed with intraoperative sentinel lymph node identification and the optional injection of non-radioactive dye. This code captures a combined diagnostic and therapeutic surgical service used in the management and staging of head and neck malignancies and other conditions involving cervical lymphadenopathy. Nationally, accurate reporting of C7503 affects surgical case mix, quality measurement for oncologic procedures, and facility billing for operative and mapping resources.
Key payers included in coverage and benchmarking for this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of the clinical intent of the code, typical sites of service, common modifiers used with this service, and a summary of payer coverage patterns where available. The publication also outlines benchmarking metrics and policy context relevant to hospital and ambulatory surgical center billing for sentinel node procedures.
This summary provides clinicians, coding professionals, and revenue-cycle staff with a clear reference to the clinical procedure represented by C7503, the operational settings where it is commonly performed, and the payers whose policies most often influence reimbursement and prior authorization requirements. Data not available in the input includes specific payer coverage policies, associated ICD-10 diagnoses, taxonomies, and related billing codes.
Billing Code Overview
HCPCS Level II code C7503 describes an open biopsy or excision of deep cervical lymph node(s) with intraoperative identification (for example, mapping) of sentinel lymph node(s). The procedure includes injection of non-radioactive dye when performed. This service is a surgical diagnostic and therapeutic procedure focused on cervical (neck) lymphatic tissue with sentinel node mapping.
Service type: Open surgical biopsy or excision with sentinel lymph node mapping and dye injection.
Typical site of service: Hospital operating room or ambulatory surgical center where open cervical surgical procedures and intraoperative mapping are performed.
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with a palpable deep cervical mass and suspicious findings on ultrasound and core needle biopsy is scheduled for an open excision of the deep cervical lymph node with intraoperative sentinel lymph node identification. The clinical workflow begins with preoperative evaluation by the surgical oncologist and anesthesiologist, verification of imaging and biopsy results, and informed consent that describes excision plus sentinel node mapping. Intraoperatively, the surgeon exposes the deep cervical nodal basin, injects a non-radioactive dye (e.g., isosulfan blue or methylene blue) around the primary tumor or in the peritumoral area, performs direct visualization and mapping to identify sentinel lymph nodes, and excises the targeted deep node(s). Specimens are labeled and sent to pathology for frozen section when indicated and for permanent histopathology. Postoperative care includes wound monitoring, pain control, and pathology-driven decisions regarding further neck dissection or adjuvant therapy based on sentinel node status.
