This procedure involves taking three X-ray images of the knee from different angles to evaluate bone structure, joint alignment, and potential injuries. Patients typically receive this imaging after knee injuries, persistent pain, or when doctors suspect fractures or arthritis. Code 73562 charges can vary significantly between outpatient facilities and hospital settings, with potential billing differences of several hundred dollars depending on the care location.

Common billing errors
Common radiology billing errors include incorrect bundling of imaging procedures, where facilities separately bill components that should be included in comprehensive codes. CT and MRI studies frequently show charges above the benchmark when contrast administration (codes 36000-36299) is billed separately despite being included in the primary imaging code. Duplicate billing occurs when both screening and diagnostic mammography codes are submitted for the same visit, or when bilateral imaging procedures are coded as two separate unilateral studies rather than using appropriate bilateral modifiers. Another frequent error involves confusion between similar imaging codes, such as billing high-resolution CT scans when standard chest CT was performed, creating potential differences of several hundred dollars. Patients should verify that contrast injections aren't separately itemized for procedures already including contrast, confirm bilateral studies use proper coding rather than duplicate unilateral charges, and ensure screening versus diagnostic imaging codes match the actual clinical indication documented in their medical records.
What to check on your bill
When reviewing your radiology bill, first verify the CPT codes match the actual procedures performed—common codes include 70450-70470 for CT scans, 72100-72170 for spine X-rays, and 73000-73700 for extremity imaging. Check that technical and professional components are billed correctly; you should see modifier -TC for the technical component (equipment/technologist) and -26 for professional component (radiologist interpretation), or no modifier if both are included. Confirm the anatomical site and laterality modifiers are accurate—modifier -RT for right side, -LT for left side, and -50 for bilateral procedures when applicable. Review facility fees separately from physician fees, as these appear as distinct line items. Compare your charges against Medicare fee schedules or regional benchmarks, as charges above the benchmark may indicate potential differences worth investigating with your insurance provider or facility billing department.
