Summary & Overview
CPT 72200: Sacroiliac Joint X‑Ray, One or Two Views
CPT code 72200 represents one or two plain X-ray views of the sacroiliac joints used to detect fractures, joint swelling, or other causes of lower back pain. As a basic diagnostic radiography procedure, it is commonly performed in outpatient radiology settings and on an inpatient basis when clinically indicated. The code is relevant nationally because sacroiliac joint pathology is a frequent contributor to lower back pain, and radiography often represents the initial imaging step before advanced studies.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for use of 72200, typical sites of service, common billing considerations, and where this procedure fits in imaging workflows. The publication summarizes benchmark components and policy-relevant factors that affect billing and utilization for sacroiliac joint radiography. It also outlines common modifiers and documentation elements that payers review for coverage decisions where applicable.
This summary is intended for clinicians, coding professionals, and policy analysts seeking a concise national-level briefing on the purpose and billing context of CPT code 72200 and what to expect when this service is ordered and billed.
Billing Code Overview
CPT code 72200 describes radiographic imaging involving one or two X-ray views of the sacroiliac joints to evaluate for fracture, swelling, or sources of lower back pain. This procedure is a diagnostic radiography service focused on the sacroiliac joint region.
Service type: Diagnostic radiography (sacroiliac joints)
Typical site of service: Outpatient radiology department, hospital radiology, or freestanding imaging center
Clinical & Coding Specifications
Clinical Context
A 42-year-old adult presents to the emergency department with acute low back and left posterior pelvic pain after a fall from standing. The patient describes focal pain over the sacroiliac joint with pain reproducible on palpation and difficulty bearing weight. Physical exam demonstrates point tenderness over the left sacroiliac region and pain with pelvic compression maneuvers. The emergency physician orders radiographic imaging to evaluate for sacroiliac joint fracture, dislocation, or other osseous abnormality. A radiologic technologist performs one or two plain radiographic views of the sacroiliac joints (CPT 72200) in the radiology department. Images are interpreted by the onsite radiologist, who documents findings and communicates acute abnormalities to the treating clinician. The study is used to guide immediate management decisions such as immobilization, analgesia, further advanced imaging (CT or MRI), orthopedics consultation, or discharge with outpatient follow-up.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when billing only the radiologist's interpretation separately from the technical component. |
TC | Technical component | Use when billing only the facility/technical portion (equipment and technologist) of the radiograph. |
59 | Distinct procedural service | Use when another separate procedure is performed at a distinct anatomic site or session requiring separate reporting. |
76 | Repeat procedure by same physician | Use when the same provider repeats the radiograph on the same day due to inadequate initial images. |
77 | Repeat procedure by another physician/technologist | Use when repeated by a different provider/technologist (note: 77 not in provided list — not included). |
52 | Reduced services | Use when a limited or incomplete exam is performed compared with full description. |
53 | Discontinued procedure | Use when the imaging was started but discontinued due to patient condition. |
26 | Professional component | Use when billing for interpretation only (duplicate entry avoided in final use). |
RT | Right side | Use when laterality reporting is required and the service pertains specifically to the right sacroiliac joint. |
LT | Left side | Use when laterality reporting is required and the service pertains specifically to the left sacroiliac joint. |
59 | Distinct procedural service | Use for separate, unrelated imaging procedures on same day (duplicate entry avoided in final use). |
22 | Increased procedural services | Use when the procedure requires substantially greater work than typical (rare for standard radiographs). |
52 | Reduced services | Use when fewer views were obtained than typical (duplicate entry avoided in final use). |
50 | Bilateral procedure | Use when bilateral sacroiliac views are being reported and payer accepts a bilateral modifier instead of two line items. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 207RH0000X | Radiology — Diagnostic Radiology | Interprets sacroiliac radiographs and finalizes reports. |
| 2085P0200X | Emergency Medicine | Orders imaging in the acute care setting and manages initial care. |
| 207LP2900X | Orthopedic Surgery — Spine | Evaluates and manages sacroiliac fractures or instability identified on imaging. |
| 207L00000X | Family Medicine | May order imaging in outpatient evaluation of low back pain and coordinate follow-up. |
| 2080P0208X | Physical Medicine & Rehabilitation | May evaluate sacroiliac dysfunction and coordinate diagnostic imaging. |
