CPT 70190Radiology

X-ray exam of eye sockets

CPT code 70190 covers X-ray imaging of the eye sockets (orbits), the bony structures that surround and protect the eyeballs. This is a standard radiographic examination used to detect fractures, foreign objects, or abnormalities in the orbital bones.

Billing tips

Split bill between professional (26) and technical (TC) components in facility settings to ensure both provider and facility receive appropriate reimbursement
Impact: Maximizes revenue capture in hospital/facility settings; prevents leaving money on the table for either component
Document specific clinical indication (trauma, foreign body, pre-op) rather than vague symptoms to support medical necessity
Impact: Reduces denial rate by 40-60%; orbital X-rays without clear indication are frequently denied as not medically necessary
Do not bill 70190 with comprehensive facial X-ray codes (70150, 70160) for the same encounter as orbits are included in facial series
Impact: Prevents unbundling denials and potential audit flags; avoiding this error saves the full $36.23 from recoupment
Use appropriate laterality modifiers (RT/LT) when imaging only one orbit to support medical necessity and proper anatomical documentation
Impact: Strengthens claim defensibility during audits and may prevent denials based on lack of specificity
Verify that CT or MRI of orbits (70480-70482) was not performed same day, as advanced imaging typically replaces plain films
Impact: Prevents denials for duplicate or medically unnecessary imaging; payers commonly deny plain films when cross-sectional imaging is performed
Link to appropriate ICD-10 diagnosis codes (S02.3, S05.5, H05 series) that clearly support the need for orbital imaging
Impact: Ensures payment at full $36.23 rate; vague or unsupported diagnoses result in 25-35% denial rate for this code

Frequently asked questions

What is the Medicare reimbursement rate for CPT 70190 in 2025?

The 2025 Medicare national average reimbursement for CPT 70190 is $36.23 for both facility and non-facility settings. This rate is based on 1.12 total RVUs multiplied by the 2025 conversion factor of 32.3465.

Can you bill CPT 70190 with a facial bone X-ray on the same day?

Generally no - CPT 70190 (orbital X-rays) should not be billed separately when comprehensive facial bone series (70150, 70160) are performed, as orbital views are typically included in facial bone studies. Billing both constitutes unbundling and will likely be denied. Use modifier 59 only if there is a distinct, separate clinical indication documented for additional orbital-specific views beyond the facial series.

What diagnosis codes support medical necessity for CPT 70190?

Common supporting diagnoses include orbital fractures (S02.3- series), orbital foreign body (S05.4-, S05.5-), eye injury (S05.-), disorders of orbit (H05.- series), facial trauma (S00-S09), and pre-operative evaluation codes. The diagnosis must clearly justify why orbital imaging is medically necessary rather than observation or advanced imaging.

Do I need to use modifier 26 or TC when billing CPT 70190?

Yes, in split-billing situations. Use modifier 26 for professional component (physician interpretation only) and modifier TC for technical component (equipment/technologist services). In hospital settings, the facility bills with TC modifier while the radiologist bills with 26 modifier. In office settings where the provider owns the equipment, bill the global service without modifiers to receive the full $36.23.

How many RVUs is CPT code 70190 worth in 2025?

CPT 70190 has 1.12 total RVUs in 2025, consisting of 0.21 work RVUs, 0.89 practice expense RVUs (both facility and non-facility), and 0.02 malpractice RVUs. These values are from the CMS Medicare Physician Fee Schedule RVU25A released December 23, 2024.

When should I use RT or LT modifiers with CPT 70190?

Apply RT (right) or LT (left) modifiers when imaging only one orbit and laterality is clinically significant to the service and diagnosis. This is appropriate for unilateral trauma, foreign body in one eye, or pre-operative planning for single-orbit surgery. Bilateral orbital imaging typically does not require modifiers unless payer-specific rules mandate bilateral indicators.

Why would an orbital X-ray claim for CPT 70190 be denied for medical necessity?

Denials often occur because CT scanning has largely replaced plain X-rays for orbital evaluation in many clinical scenarios. Payers may consider orbital X-rays not medically necessary when more definitive imaging is appropriate, when clinical presentation doesn't warrant imaging, or when used for routine screening without symptoms. Strong documentation of appropriate use cases (initial trauma assessment, foreign body detection, cost-effective alternative) is essential to prevent denials.
