2025 CPT code 70480

Computed tomography (CT) scan of the orbit, sella, posterior fossa, or inner/middle/outer ear without contrast.

Follow all standard radiology coding guidelines. Ensure proper modifier use as needed (26, TC) based on payer guidelines.Consider separate billing for contrast if administered and per payer rules.

Modifiers 26 (professional component) and TC (technical component) may be appended as appropriate based on payer guidelines and who performed which part of the service.

Medical necessity is established by the presence of symptoms or findings suggesting pathology within the targeted anatomical region (orbit, sella, posterior fossa, or ear).Appropriate clinical indication must be documented.

The physician positions the patient, operates the CT scanner, acquires the images, and interprets the results to identify any pathology.

IMPORTANT:For a similar study with contrast, see CPT code 70481. For a similar study with and without contrast, see CPT code 70482.If oral or rectal contrast is used, code as without contrast. For intravascular, intraarticular, or intrathecal contrast, a code including contrast should be used.Separate reporting of contrast material may be necessary depending on payer guidelines, using codes such as 99070 or a HCPCS Level II code.Modifier 26 (professional component) or TC (technical component) may be appended as per payer policy.

In simple words: This medical code describes a CT scan of the eye socket, the area near the pituitary gland at the base of the skull, the back part of the skull, or the inner, middle, or outer ear.No special dye is used during this scan.

This CPT code 70480 represents the performance of a computed tomography (CT) scan of the orbit, sella turcica, posterior fossa, or the inner, middle, or outer ear structures.The procedure specifically excludes the administration of any contrast material. The examination involves positioning the patient within the CT scanner, acquiring cross-sectional X-ray images of the designated anatomical area, and generating computer-processed image slices for interpretation. These images aid in the identification of tumors, anatomical abnormalities, and foreign bodies.

Example 1: A patient presents with sudden onset of blurry vision and suspected orbital trauma. A non-contrast CT scan (70480) is ordered to evaluate for fractures or hemorrhage., A patient with a history of headaches undergoes a CT scan (70480) of the posterior fossa to rule out structural abnormalities like tumors or aneurysms., A patient complains of persistent ear pain and hearing loss.A non-contrast CT scan (70480) of the temporal bone is performed to assess for inner ear infection or ossicular chain disruption.

Detailed clinical history indicating the reason for the CT scan.Radiology report including image interpretation and findings.Imaging images themselves.

** The absence of contrast material is crucial for this code.Always verify payer specific policies regarding contrast material and modifier usage.
