What is a hip x-ray, 2 - 3 views?

CPT code 73502 describes a radiologic examination of the hip joint, with two to three views (commonly anteroposterior and lateral). This hip X-ray service is typically ordered to assess conditions such as joint pain, suspected fractures, dislocations, or degenerative diseases like arthritis. The exam captures detailed images of the hip area, focusing on one hip only, and is essential for evaluating the lower extremities in trauma or orthopedic care.

Used widely by healthcare providers in urgent care, emergency departments, and outpatient settings, this diagnostic imaging study plays a vital role in orthopedic assessments and pre-surgical planning.

CPT code 73502 documentation requirements

To ensure accurate reporting and support for medical necessity, documentation must include:

Clinical indication (e.g., trauma, chronic pain, suspected fracture)
Views performed (at least two)
Laterality (right or left hip; use modifier LT or RT)
Radiologist’s interpretation with findings and final impression
Technical component details, including machine settings and image quality
Date of X-ray and confirmation that it was performed in the same session

All documentation should be signed by the interpreting radiologist.

CPT code 73502 billing guidelines

To correctly bill for code 73502, follow these best practices:

Report once per hip; if both hips are examined, submit 73502 x 2 with appropriate modifiers (RT/LT or modifier 50) depending on payer preference.
Do not use this code for single-view hip X-rays (see CPT 73501)
Global billing includes both the technical component (imaging equipment and technician time) and the professional component (radiologist interpretation).
Use modifier -26 (professional) or -TC (technical) for split billing.
Always refer to American Medical Association CPT guidelines or your payer’s policy for updates or new codes.
