Summary & Overview
CPT 72202: Sacroiliac Joint X‑ray, Three or More Views
CPT code 72202 represents diagnostic radiographic imaging of the sacroiliac joints using three or more X‑ray views to evaluate fracture, swelling, or sources of lower back pain. As a focused musculoskeletal imaging procedure, it informs clinical decisions for patients presenting with pelvic or lumbosacral pain and can be a gateway to additional imaging or specialist referral. Nationally, consistent use of appropriate sacroiliac joint imaging affects care pathways, utilization of advanced imaging, and billing accuracy across payers.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the procedure, typical sites of service, and the common modifiers and billing considerations associated with the service line. The publication summarizes benchmark considerations, coding nuances, and implications for claims processing and prior authorization workflows. It also highlights what to expect in terms of documentation elements that support medical necessity and claim adjudication.
This article is intended for a national audience of billing professionals, practice managers, radiology providers, and payers who need a practical reference for CPT code 72202, its clinical role, and how it fits into broader imaging and musculoskeletal care pathways.

Clinical & Coding Specifications
Clinical Context
A 46-year-old patient presents to the emergency department with acute low back pain after a fall from standing height with focal pain over the sacroiliac region and limited ambulation. The emergency physician performs an initial history and physical examination, documents localized sacroiliac tenderness, and orders radiographic imaging to evaluate for fracture, dislocation, or other bony abnormality. The patient is escorted to the radiology suite where a diagnostic radiologic technologist obtains at least three views of the sacroiliac joints using fluoroscopy or standard radiography positioning. The study is interpreted by an on‑site radiologist who provides a final report indicating the presence or absence of fracture, joint widening, sacroiliitis changes, or other pathology. Results are communicated to the referring clinician for disposition (pain control, orthopedic referral, further imaging such as CT or MRI, or discharge with follow-up). Typical documentation includes indication, number and type of views, technique, comparison studies if available, and the interpreting radiologist’s impression.
