CPT 73070: Elbow X‑ray, Minimum 2 Views
CPT code 73070 identifies diagnostic radiography of the elbow with at least two views. Extremity X‑rays, including elbow imaging, are a common first‑line diagnostic tool for acute injury, suspected fracture, degenerative joint disease, and other osseous pathology. Nationwide, this imaging code is widely used across outpatient imaging centers, emergency departments, urgent care clinics, hospital outpatient departments, and physician offices where portable or stationary radiography is available.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical indications and settings for use, common billing modifiers and coding context, prevailing coverage patterns among major payers, and benchmarking information where available. The content summarizes how CPT code 73070 fits into typical care pathways for elbow injury and musculoskeletal complaints and outlines administrative considerations relevant to claims processing and documentation.
This national overview focuses on clinical and billing context, payer coverage landscape, and where to find relevant policy or reimbursement guidance. Data not available in the input is noted where applicable.

Billing Code Overview
CPT code 73070 describes radiographic imaging of the elbow with a minimum of two views. These extremity X-rays evaluate injury, fracture, arthritis, bone spurs, tumors, or congenital abnormalities by imaging the affected elbow and, when indicated, comparison views of the unaffected site.
Service type: Diagnostic radiology — extremity X‑ray (elbow), minimum 2 views
Typical site of service: Radiology suite or imaging center; hospital outpatient department; emergency department; urgent care clinic; office-based imaging
Clinical & Coding Specifications
Clinical Context
A 34-year-old adult presents to an urgent care clinic after falling onto an outstretched hand with localized pain, swelling, and limited elbow range of motion. The treating clinician performs a focused musculoskeletal exam that raises concern for an acute elbow fracture or dislocation. To evaluate for bony injury, two-view 73070 radiographs of the affected elbow (typically anteroposterior and lateral views) are ordered and performed on-site. Images are interpreted by the facility radiologist or the treating clinician; results are used to determine urgent management such as splinting, orthopedic referral, or further imaging (e.g., additional views, comparison radiographs, or advanced imaging). Typical site of service is an outpatient radiology suite, urgent care center, emergency department, or clinic with radiographic capability. Service type: diagnostic radiology — extremity X-ray (minimum of 2 views) focused on the elbow.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
RT | Right side | Used when the 73070 radiograph is of the right elbow to indicate laterality |
LT | Left side | Used when the 73070 radiograph is of the left elbow to indicate laterality |
TC | Technical component | Used when billing only the technical component (equipment, tech staff) of the radiograph |
26 | Professional component | Used when billing only the professional component (interpretation/report) |
59 | Distinct procedural service | Used when another separate radiographic service or procedure is performed at the same encounter and must be distinguished from 73070 |
52 | Reduced services | Used when fewer views than typical are taken or the study is partially reduced in scope |
53 | Discontinued procedure | Used when the radiographic exam was started but discontinued for patient safety or intolerance |
77 | Repeat procedure by another physician | Used when images are repeated by a different provider due to technical issues |
76 | Repeat procedure by same physician | Used when the same provider repeats the radiograph for additional images due to positioning/technical error |
50 | Bilateral procedure | Rare for 73070 but used if both elbows are imaged and payer requires a bilateral modifier |
91 | Repeat clinical diagnostic laboratory test | Not typically used for radiography; listed among common modifiers but not generally applicable to 73070 |
27 | Multiple outpatient hospital E/M visits on same date | Used when multiple visits occur same day that may affect billing context (administrative use) |
22 | Increased procedural services | Used when documentation supports unusually high complexity relative to typical elbow X-ray (rare) |
25 | Significant, separately identifiable E/M service | Used when a separate evaluation and management service is provided on the same day as 73070 and is documented distinctly |

| CPT Code | Description | Relationship to This Procedure |
|---|---|---|
73030 | Radiologic examination, humerus, minimum of two views | Performed when injury or evaluation extends proximally from the elbow to the humerus; may be ordered alongside 73070 if concern involves the distal humerus |
73040 | Radiologic examination, forearm, minimum of two views | Performed when suspected injury involves the forearm bones (radius/ulna) contiguous with the elbow; may be ordered in addition to 73070 |
73060 | Radiologic examination, elbow, complete, minimum of three views | Performed when a more comprehensive elbow series is required; if three or more views are taken, 73060 may be the appropriate code instead of 73070 |
73090 | Radiologic examination, elbow, with comparison views | Used when comparison radiographs of the contralateral elbow are obtained in addition to the injured side |
73070 | Radiologic examination, elbow, minimum of two views | Primary procedure described here; focused two-view elbow radiographs used for initial evaluation of trauma or pathology |
