Summary & Overview
CPT 24065: Biopsy of Upper Arm or Elbow Mass
CPT code 24065 represents an open surgical biopsy of a mass in the upper arm and elbow region performed to obtain tissue for pathologic diagnosis, including assessment for cancer. As a procedure-level surgical code, it is relevant to surgical oncology, orthopedics, and general surgery practices and has implications for facility billing, preauthorization workflows, and pathology services nationwide. Key national payers in scope for this code include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise overview of what CPT code 24065 covers clinically, common sites of service, and the types of documentation and coding context typically associated with upper-extremity mass biopsies. The publication outlines benchmark topics such as utilization patterns, coding and billing considerations, and payer coverage themes where available. It also summarizes clinical context—why tissue diagnosis matters for treatment planning—and points to areas where policy updates or payer-specific requirements commonly influence billing and prior authorization processes. Data not available in the input is identified where applicable.
Billing Code Overview
CPT code 24065 describes an open biopsy of a mass located in the upper arm and elbow region. The procedure involves surgical removal of all or part of a suspicious lump to obtain tissue for histologic examination to determine malignancy.
-
Service type: Surgical biopsy (open/incisional or excisional biopsy) of soft tissue mass in the upper arm/elbow area
-
Typical site of service: Hospital operating room, ambulatory surgery center, or outpatient surgical clinic
Clinical & Coding Specifications
Clinical Context
A 54-year-old patient presents to an outpatient surgical clinic with a palpable, firm, 2.5 cm subcutaneous lump in the lateral aspect of the upper arm near the elbow following several weeks of progressive growth and intermittent pain. Physical exam raises concern for a neoplasm versus benign soft-tissue mass. The patient is scheduled for an excisional or incisional biopsy of the mass to obtain histopathology. Typical workflow: pre-procedure history and consent in clinic; site marking and local anesthesia on day of procedure; sterile prep in an ambulatory surgery center or hospital outpatient department; performance of either an excisional biopsy (removal of entire lesion) or incisional/core biopsy (sampling portion of lesion) of the upper arm/elbow region; specimen submission to pathology with appropriate labels and requisition; post-procedure wound care instructions and follow-up for pathology results and further oncologic management if indicated.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
LT | Left side | Use when biopsy performed on the left upper arm/elbow to denote laterality. |
RT | Right side | Use when biopsy performed on the right upper arm/elbow to denote laterality. |
