Summary & Overview
CPT 24220: Elbow Arthrography with Contrast Injection
CPT code 24220 denotes arthrographic injection of contrast into the elbow joint to improve radiographic visualization of intra-articular structures and aid diagnosis of cartilage, ligament, or bony pathology. Nationally, this code supports diagnostic workflows that complement advanced imaging when assessing unexplained elbow pain, suspected intra-articular derangements, or preoperative evaluation. The procedure matters because accurate joint visualization can change downstream imaging, intervention, and surgical planning.
This publication reviews coverage and reimbursement considerations for major national payers: Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the service, typical sites of care, and the common modifiers and billing considerations associated with the code. The analysis outlines expected billing use cases, potential documentation priorities, and comparisons of payer coverage practices where available. Additional sections cover coding nuances, related imaging services, and areas where policy updates or payer-specific rules frequently influence claims adjudication.
Intended for billing managers, radiologists, orthopedic specialists, and revenue cycle staff, the summary provides a practical reference for when and how CPT code 24220 is applied in diagnostic elbow arthrography and what to expect from national payers.
Billing Code Overview
CPT code 24220 describes injection of contrast material into the elbow joint cavity to enhance radiographic imaging for evaluation of internal joint structures such as cartilage, ligaments, and bone. The procedure facilitates visualization of intra-articular anatomy to help diagnose joint conditions and unexplained elbow pain.
-
Service type: Image-guided diagnostic intra-articular contrast injection
-
Typical site of service: Outpatient radiology suite or ambulatory surgical/ procedural center; may also be performed in hospital outpatient departments

Clinical & Coding Specifications
Clinical Context
A 48-year-old patient presents to the orthopedic clinic with persistent lateral elbow pain and mechanical symptoms after a remote throwing injury. Conservative care including rest, NSAIDs, and a course of physical therapy has not relieved symptoms. Physical exam reveals joint line tenderness and limited range of motion. The orthopedic surgeon schedules an elbow arthrography to evaluate suspected intra-articular pathology such as cartilage injury, loose bodies, or occult fractures prior to possible arthroscopy. The patient arrives to an outpatient imaging suite or ambulatory surgery center. After informed consent and sterile preparation, the provider palpates the elbow joint, uses fluoroscopic or ultrasound guidance to confirm intra-articular needle placement, and injects iodinated contrast material into the elbow joint cavity. Post-injection imaging (fluoroscopy and/or radiographs) is obtained to assess joint spaces, cartilage outlines, and the presence of intra-articular defects. The procedure may be billed with 24220 for contrast injection into the elbow joint and is followed by diagnostic image interpretation and, if indicated, referral for arthroscopy or further imaging.
